Research Discussion Paper – RDP 2021-06 What Is Driving Participation and Diversity Trends in Economics? A Survey of High School Students

1. Introduction

There has been a dramatic decline in Australia's Year 12 Economics enrolments of around 70 per cent over the past 3 decades (Figure 1). Alongside the decline in numbers, the gender balance has diminished from roughly equal numbers of male and female students in the early 1990s, to males outnumbering females two-to-one in recent years. In the state of New South Wales, for which more detailed data are available, the shares of students from low socio-economic backgrounds and regional locations have also fallen substantially (Figure 2).

The size and diversity of the Economics student population matters for both students and broader society. Economics at the high school level provides a basic level of economic literacy. While there is no one definition of economic literacy, it encompasses an ability to apply economics skills and frameworks to explain or debate much of the world in which we live – from understanding opportunity costs in our personal decisions, through to forming a view about the efficacy of economic policies. In New South Wales, and most other Australian states, the main opportunity high school students have to learn basic economic literacy is through the Year 11 and 12 Economics syllabus (Board of Studies New South Wales 2009).[1] The syllabus teaches fundamental macroeconomic and microeconomic frameworks and concepts, equipping students to engage with current economic issues. Other subjects touch on some Economics concepts, but arguably do not provide a generalised foundation of economic literacy.[2]

While there have been numerous studies of financial literacy relating to an individual's personal finances (e.g. Lusardi 2019), there is little evidence pertaining to economic literacy. In the Australian context, the Household, Income and Labour Dynamics in Australia (HILDA) Survey provides a financial literacy test that covers concepts that can also be considered as part of economic literacy (in particular, interest rates, inflation and money illusion). Using this test, only around half of Australian adults would be considered ‘financially literate’ (Preston 2020). This may be indicative of economic literacy more broadly. There is some evidence of adults declaring a desire for greater economic literacy; in a survey of UK residents, while nearly two-thirds of respondents had not studied any economics, three-quarters thought that economics should form part of the school curriculum (Lait 2017). Indeed, in the follow-up 2019 study, around half of the respondents wanted to increase their understanding of economics of the real world and know more about economics to help them make decisions in elections and referendums (Lait 2019).

As studying Economics is often the start of a pathway to a career in economics, the diversity of the student body ultimately shapes the discipline. Declining participation (relative to other subjects) and widening diversity gaps have also been observed for economics enrolments at Australian universities (Dwyer 2018). With economists playing an integral role in determining economic policies, there are wider social benefits when the pipeline of future economists is broadly representative of society. For example, May, McGarvey and Whaples (2014) find that male and female economists have different views on economic outcomes and policies, lending support to the notion that gender diversity amongst policymakers may be an important aspect in expanding the menu of public policy choices.

Qualitative evidence from the RBA's liaison with educators indicates that a number of factors may explain the decline in Economics enrolments. First, too few educators are equipped to teach Economics and too little relevant Australian economics content is available, providing school leaders with limited incentive to offer (or promote) the subject. Second, it has been reported that many students do not select Economics because they do not understand what it is and how it might be relevant to them. Indeed, until the COVID-19 pandemic, there had been a lengthy period in which Australian households were not exposed to a major economic contraction or the extensive economic reforms that were a feature of national debate in the 1980s and early 1990s, drawing less attention to the relevance of economics to everyday life. Third, the introduction of Business Studies to the New South Wales Higher School Certificate (HSC) in the early 1990s saw a large number of students take up the subject instead of Economics, with reports that Business Studies, which is more vocationally orientated, is perceived as being easier to learn and more helpful for employment (Figure 3).

Through this liaison, educators have provided valuable qualitative insights into some of the broad constraints on Economics enrolments. However, a comprehensive survey of students themselves was needed to gain quantitative evidence of the student demand-side factors contributing to the decline in Economics enrolments, and particularly the diversity trends. As such, the RBA commissioned a survey to ask students about how and why they choose subjects, as well as what is influencing their preference for Economics (in particular their perceptions of Economics).

The RBA-led survey also helps us fill a gap in the literature. It contains a unique primary source of data with which to examine the drivers of falling participation and diversity in economics.

Surveys (which vary in scale) of university students have found perceptions of economics to be largely negative (see Webber and Mearman (2012)). For students at Australian universities at least, economics is generally viewed as abstract, difficult, dull and boring, not relevant to the real world, lacking an ethical dimension, and not obviously associated with a high-profile profession or clear career path (Lewis and Norris 1997; Ward, Crosling and Marangos 2000; Azzalini and Hopkins 2002). At issue is the extent to which these perceptions are representative of high school students and have bearing on their subject selection.

Furthermore, while there are many studies that examine aspects of the relationship between students' characteristics and subject or careers choices, the fields of study are broadly defined. Economics is rarely separately identified. For example, studies (some of high school students and others of university students) have utilised large-scale datasets to draw associations between study choices and student characteristics. (For key Australian examples, see use of the Longitudinal Survey of Australian Youth by Fullarton and Ainley (2000), Fullarton et al (2003) and Thomson (2005)). Relatedly, there are many studies that seek to explore subject selection as part of a student's decision-making process when choosing a career. They have little to say, though, about choosing economics – either as a subject or a career (see Alloway et al (2004); Gore et al (2017); Jung and Young (2019)).

Consequently, despite there being a large body of literature that draws on surveys of students at different stages of their learning, no published research in Australia or internationally has drawn on surveys of high school students' perceptions of economics, or what determines their decision to study (or not study) economics in senior high school. This paper addresses 3 key questions:

  1. Which school and individual characteristics are most strongly associated with choosing Economics?
  2. What are students' perceptions of Economics?
  3. What differences in perceptions of Economics exist by sex and socio-economic background?

The remainder of this paper is structured as follows. Section 2 describes the unit record survey data and administrative data that are used to estimate the model specifications that address our key questions. Section 3 describes each specification and the corresponding results, progressively controlling for more explanatory factors, shedding light on the scope for interventions and further avenues for research discussed in Section 4.

2. Data

2.1 Survey

The RBA collaborated with Ipsos to undertake the ‘High School Students’ Subject Selection Survey' of Year 10, 11 and 12 students in New South Wales in 2019. We chose to survey schools in New South Wales, rather than other states, as a rich set of school-level data is already available to the RBA about students in this state to supplement the analysis. There are also extensive permissions processes and logistical challenges that vary across the state education systems, which made it infeasible to survey multiple states in a timely way.

The overarching aim was to ensure that we generated a representative sample of the New South Wales Year 10, 11 and 12 student population for our analysis. The sampling frame (or relevant population) consisted of 770 schools in New South Wales after excluding institutions deemed out of scope or without approval to approach.[3]

The sample population was stratified at the school level to attain a sample with representative coverage of the government and non-government sectors, and metro and regional locations. A total of 51 schools completed the survey between July and September 2019.[4] The schools fall within 8 strata, covering school sector (government or non-government), school type (co-ed, all girls or all boys) and location (metro or regional) (Table 1).

Each participating school was asked to administer the survey to as many Year 10, 11 and 12 students as they were willing. Schools were more willing to administer the survey to Year 10 students, compared with the senior years (Table 2). A total of 4,826 students completed the survey. The survey was completed in class by students on computers or devices under the supervision of a teacher.[5] Responses identified as being from potential ‘skimmers’ (i.e. students who completed the survey in an implausibly short time) were excluded, yielding a final sample of 4,698 responses. The characteristics of the sample are broadly representative of the New South Wales (NSW) student population in terms of sex, school sector and geographical area (see Appendix A).[6] Of Year 11 and 12 students in the sample, 10 per cent study Economics, consistent with the state-wide figures.

The questionnaire design was informed by focus groups with Year 10, 11 and 12 students to ensure that the factors contributing to subject selection, and the drivers and barriers to selecting Economics, were adequately represented and in appropriate language.[7] For Year 10 students, questions related to their subject selection intentions for Year 11 and 12.[8] Students in Year 11 and 12 were asked to reflect on the reasons for choosing the subjects they did.

2.2 Administrative enrolments data

To enrich the unit record survey data, and establish the relative importance of school characteristics, we draw on administrative data provided by the NSW Education Standards Authority (NESA) for 2019. These data provide Year 12 Economics enrolments, the size of the total Year 12 cohort, the number of Year 12 subjects taught, and information about each schools sector (government or non-government), school type (co-ed, all girls or all boys) and location (metro or regional). The measure of socio-economic status used in this paper is the 2019 Index of Community Socio-Educational Advantage (ICSEA) score for each school.[9] (This score is derived from a number of variables including parental education and occupation, the school's location and proportion of Indigenous students.)

3. Empirical Approach and Results

3.1 Which school and individual characteristics are most strongly associated with choosing Economics?

To ascertain the school and individual characteristics that are most strongly associated with choosing Economics, we consider a number of model specifications (Table 3).

Table 3: Model Specifications
Dependent variable Data Method Interpretation of coefficients
EconSchoolj = 1 if school j has at least 1 Economics student; 0 otherwise Year 12 enrolments for all NSW high schools; administrative data Probit The effect of school characteristics on the likelihood of a school teaching Economics, all else equal. May reflect factors from the supply side (school's inclination to offer Economics as a subject choice) and demand side (student's inclination to choose Economics).
EconShar e j = Econenrolment s j HSCenrolment s j where Econ enrolmentsj is the number of Economics enrolments and HSC enrolmentsj is the total number of Year 12 students (awarded a HSC)
EconSharej > 0if EconSchoolj = 1;
EconSharej = 0if EconSchoolj = 0
Year 12 enrolments for all NSW high schools; administrative data Heckman The effect of school characteristics on the proportion of students taking Economics, all else equal. Reflects demand-side factors (student's inclination to choose Economics).
EconStudentij = 1 if student i from school j is an Economics student; 0 otherwise
EconStudentij = 0 if EconSchoolj = 0
Year 11 and 12 students in all sampled schools; survey data (supplemented with administrative school-level details matched to the student record) Heckprobit The effect of individual and school characteristics on the likelihood of a student choosing Economics), all else equal. Reflects demand-side factors (student's inclination to choose Economics).

Utilising administrative data on all schools in NSW, we first examine the importance of school characteristics for whether or not a school teaches Economics (Table 4, column (1)). For a school to be teaching Economics, both supply and demand conditions must be met: (i) they offered Economics as a subject choice (i.e. they were not constrained by a teacher/resource shortage); and (ii) students selected Economics (i.e. enough students chose Economics to meet a minimum class size). As such, the coefficients in our first specification (column (1)) may reflect factors from both the school supply side and student demand side. We find that schools are significantly more likely to teach Economics if they have a higher socio-economic status, a larger Year 12 cohort, teach a larger variety of subjects, or are all boys. For example, a 100 point (i.e. 1 standard deviation) increase in ICSEA is associated with a 16 percentage point increase in the likelihood of studying Economics, holding all other variables at their means. All else equal, school sector (government versus non-government) and location (regional versus metro) are not significant factors in the likelihood of a school teaching Economics.

To isolate the student demand side we examine variation in the proportion of students who take Economics (Economics enrolments as a share of the Year 12 cohort) within schools that offer Economics.[10] We estimate a Heckman model to account for the selection effect of excluding schools where Economics is not offered. The size of the Year 12 cohort is used as an exclusion restriction. All else equal, larger schools are more likely to offer Economics, and we argue that the cohort size is unlikely to affect student demand for Economics. However, larger schools may offer a greater variety of subjects, which could affect student demand for Economics, so we include the number of subjects offered as an additional control in the selection and outcome equations. The Wald test of independence of the selection and outcome equations confirms the significance of a selection effect (Table B1).

Isolating the student demand side, we find that higher socio-economic status is associated with increased demand for Economics amongst students (Table 4, column (2)); this suggests that the higher likelihood of Economics being taught at schools with higher socio-economic status (Table 4, column (1)) is not just attributable to school supply-side factors. Non-government schools experience lower demand for Economics relative to government schools, holding socio-economic status and other characteristics constant. Relative to co-ed schools, all boys schools are associated with greater student demand for Economics, and all girls schools are associated with less.

A key contribution of the student survey data is the ability to isolate the individual student characteristics from the schools' characteristics that relate to students' demand for Economics. We do this using the sample of students at schools that teach Economics, accounting for sample selection. We estimate a probit model with sample selection (heckprobit), using the size of the Year 12 cohort as an exclusion restriction (Table 4, columns (3) and (5)). The Year 12 cohort size in this model is a series of dummy variables representing size categories (rather than a continuous variable as used in the school-level estimation).[11] Standard errors are clustered by school accounting for the stratified approach to sampling.

The heckprobit estimation fails to reject the null hypothesis of independence of the selection and outcome equations; this is surprising given the significant selection effect identified using the administrative data on the population of schools (Table B1). This may reflect the lack of variation from using dummy variables rather than continuous variables when identifying the selection effect, or the smaller sample of schools included in the survey sample (particularly for Year 11 and 12 students; Table 2), rather than an absence of selection.[12] As a comparison, the model is estimated as a probit (without sample selection) using the sample of schools where Economics is taught (Table 4, columns (4) and (6)).

These estimates imply that males are more likely to choose Economics than females, even when controlling for school characteristics. This clarifies that the greater prominence of males in Economics (Figure 1) reflects differences by sex, and is not just a product of confounding school factors. We also control for bilingual status, as a proxy for ethnicity, though this is not significant. We find there is a greater likelihood of males and students from a higher socio-economic background studying Economics, even when controlling for other student characteristics (Table 4, columns (5) and (6)). For example, these results are robust to the inclusion of variables for perceived interest in Economics, perceived understanding of Economics, and whether they take into account how well a subject scales for the Australian Tertiary Admission Rank (ATAR).[13]

We find that when controlling for perceived understanding and interest in Economics, the marginal effects of being male are reduced slightly but remain significant. This provides some indication that only part of the reason that males are more likely to study Economics than females is because they tend to be more interested or have a better perceived understanding of Economics. Including these variables also renders the marginal effect of school sector insignificant. A further analysis of differences in student perceptions is explored in the following section.

Overall, we conclude that students' demand for Economics is strongly associated with socio-economic background and sex, confirming that the aggregate picture of diversity in enrolments is not driven by any confounding factors that might have been at play.

3.2 What are students' perceptions of Economics?

A novel feature of the survey data is students' perceptions of Economics, regardless of whether or not they chose it, shedding light on the reasons for lower participation and diversity in Economics enrolments. We asked students to consider a range of statements about Economics, and to indicate the extent to which they agree or disagree with each on a five-point Likert scale (from ‘strongly disagree’ to ‘strongly agree’).

What positive perceptions do students have about Economics? Students typically believe that economics can be used for social good, isn't all about money and that an economics degree leads to a wide range of career options (Table 5). They also do not tend to believe economics is more of a career for men. Students typically believe they could do well at Economics in Year 11 and 12 and that it scales well for the ATAR. They perceive that Economics provides skills for everyday life. Interestingly, these positive perceptions are in contrast to findings from surveys of Australian university students (Lewis and Norris 1997; Ward et al 2000; Azzalini and Hopkins 2002).

What negative perceptions do students have about Economics? Students generally do not perceive Economics as interesting and have little desire to know more about it. Economics is perceived as having a heavier workload than most other Year 11 and 12 subjects. And while Economics is seen as providing skills and tools for everyday life, students generally indicated they prefer to study Business Studies because they think it will be more useful for their future and more interesting. These results are in line with insights from liaison and the revealed preference for Business Studies over Economics in enrolment data. While students perceive an economics degree to lead to a wide range of career opportunities, students are less likely to have a clear understanding of Economics (the subject) or the careers available if they were to choose Economics (as a subject).

3.3 What differences in perceptions of Economics exist by sex and socio-economic background?

To investigate what attitudes and beliefs may underpin the difference in likelihood of studying Economics by sex and socio-economic background, we consider a model with the dependent variable Perceptionij, which takes the values ‘1 – Strongly disagree’, ‘2 – Tend to disagree’, ‘3 – Neither agree nor disagree’, ‘4 – Tend to agree’ or ‘5 – Strongly agree’ for each perception statement. We estimate an ordered probit model with school-level and student-level variables. These questions are asked to Year 10, 11 and 12 students.

We find that females were less likely than males to ‘have a good understanding of what Economics is’, ‘find Economics interesting as a subject’ or ‘want to know more about Economics’ (Table 6). For example, males are 4 percentage points more likely than females to strongly agree with the statement ‘I have a good understanding of what Economics is’, holding all other variables at their means. Females are also less likely than males to feel ‘I could do well in Economics if I put my mind to it’ or ‘have a clear idea of whether I would be good at Economics’, and more likely to believe that Economics is ‘a risk to study because I don’t know what it is about'. Furthermore, female students perceived that teachers were less likely to promote Economics as a subject. Females were also more likely than males to perceive Business Studies as easier, more useful and more interesting than Economics. In terms of career development, females were less likely to have clear or positive perceptions of career opportunities from studying economics. However, females were less likely to perceive ‘economics is a career option for men more than women’. Importantly, these findings remained even when accounting for whether schools did or did not offer Economics in their schools.

Many of these trends were also present for students in schools with a lower socio-economic background (compared with higher socio-economic). In particular, students from a lower socio-economic background are less likely to feel ‘I could do well in Economics if I put my mind to it’ or ‘I have a clear idea of whether I would be good at Economics’. Students from a lower socio-economic background were also less likely to ‘have a good understanding of what Economics is’, or have a clear perception of career opportunities from studying economics. These students are more likely to believe that ‘it is a risk to study Economics because I don't know what it's about’.

The finding that students who are female (compared with male) and from a lower socio-economic background (compared with higher socio-economic) are less likely to ‘have a good understanding of what Economics is’ is one possible reason for differences in other perceptions about Economics. If this were the case, it would imply that interventions that increased understanding would be an efficient way to eliminate gaps in perceptions more broadly. To further investigate the relationship between understanding and perceptions, we re-estimate the regressions controlling for students' perceived understanding of Economics.

Some of the differences between sex and socio-economic background are no longer statistically significant once accounting for perceived understanding (see results with (a) superscript in Table 6). In particular, accounting for a lower perceived understanding of Economics eliminates the sex difference in the desire to ‘want to know more about Economics’, students' perceptions of teachers promoting Economics as a subject, and perceptions that ‘an economics degree leads to a wide range of career options’. Similarly, controlling for a lower perceived understanding of Economics eliminates differences between students from different socio-economic backgrounds in clarity of career opportunities from studying economics.

There still remains, however, a gap to be closed. Females are less likely than males to ‘have a clear idea of whether I would be good at Economics’ or ‘have a clear idea of the careers available to me if I were to study Economics’, and students from a lower socio-economic background are less likely to feel ‘I could do well in Economics if I put my mind to it’. It remains that females and students from a lower socio-economic background are more likely to believe that it is ‘a risk to study Economics because I don't know what it's about’ and have favourable perceptions of Business Studies. Furthermore, students from a lower socio-economic background are less likely to report that teachers at their school promote the study of Economics. And it also remains that males are more likely to find Economics interesting, controlling for a lower perceived understanding of Economics.

To shed light on whether the nature of the topics included in the Year 11 and 12 Economics syllabus appeal more to males than females, the survey gave students a list of Economics topics (based on the Economics syllabus) and asked them to select the 2 that were most interesting. The data reveal that females and males do differ in the topics they find most interesting (Figure 4). In particular, female students were more likely to cite ‘identifying problems’, whereas male students were more likely to cite the ‘share market’.

4. Discussion and Implications

This paper provides an evidence base for those engaged in Economics education – and the economics profession more broadly – to promote participation and diversity in the study of Economics. The results may also inform how educators and career advisors communicate with students about subject choices in general and Economics in particular.

High school students in our Australian survey typically have positive perceptions of economics as a field; they think that economics is used for social good and not just all about money. This implies that the core elements of economics have broad appeal. However, the perceptions of Economics as a Year 11 and 12 subject tend to be negative; for example, that Economics is not interesting, has a heavier workload than most other Year 11 and 12 subjects, and is less useful than Business Studies. A challenge in increasing overall enrolments in Economics is to build interest, relevance and understanding to motivate high school students to study Economics.

We find that socio-economic status is the key school characteristic associated with the likelihood of a student studying Economics, while sex is the key student-level characteristic. That is, students are more likely to study Economics if they are male or in a school with a higher socio-economic status. Differences in perceptions between both students of different socio-economic backgrounds and sexes reveal underlying attitudinal factors that are reflected in the divergent likelihood of studying Economics.

Importantly, females (compared with males) and students from a lower socio-economic background (compared with higher socio-economic) are less likely to perceive they ‘have a good understanding of what Economics is’. A greater perceived understanding of what Economics is about also reduces some of the sex and socio-economic differences, such as the desire to know more about Economics, perceptions of teachers promoting Economics, and clarity of career opportunities. This implies that one possible intervention to address diversity deficits in Economics is to improve students' understanding of what Economics entails. Further research may test various informational interventions to establish which content and medium work best to improve perceived understanding of Economics.

Even controlling for perceived understanding, however, females are less likely to ‘have a clear idea of whether I would be good at Economics’ and students from a lower socio-economic background are less likely to feel ‘I could do well in Economics if I put my mind to it’. Without data to control for actual academic ability, it is not clear whether these differences reflect accurate assessments of ability, opportunity to do well or a lack of confidence (for a given level of ability). Nevertheless, this result implies that interventions that only provide information (i.e. increase understanding of what Economics is) are not enough to equalise perceptions and participation in Economics. Further research, that disentangles actual ability to do well in Economics from perceived ability to do well, would shed light on the relative merits of interventions that focus on developing relevant skills and those that focus on boosting confidence in the skills already held.

We also find that males are more likely to find Economics interesting (even controlling for perceived understanding). This may reflect an inherent difference in interest in economics between the sexes. Or it may reflect that the nature of the topics included in the Year 11 and 12 Economics syllabus appeal more to males than females; we find evidence that specific topics of interest do differ between the sexes. Further work may examine how well the Economics syllabus aligns with the interests of female students.

While this paper examines data for NSW students, future research may investigate perceptions of Economics according to the stage at which students are exposed to it (with the stage at which economics content is introduced to students varying by state, with some including it as a compulsory part of the junior high school curriculum). Further work may also evaluate the effectiveness of interventions at different stages of learning.

5. Conclusion

This paper has established novel quantitative evidence of the factors contributing to the decline in high school Economics enrolments and the accompanying fall in diversity of the Economics student population. This evidence base, and resulting interventions, are a stepping stone to promoting economic literacy amongst the population and cultivating a pipeline of future economists who are more representative of society.

We also thank Gabrielle Penrose for guidance on the analysis, and members of the Reserve Bank of Australia's Educators Advisory Panel and Susan Slocum for input into the survey design. Permission to survey students was provided by the NSW Department of Education (through the State Education Research Applications Process) and eight Catholic diocesan authorities within New South Wales; while formal permission was not required, a letter of support was provided by the Association of Independent Schools of New South Wales Limited. Ethics approval (by a Bellberry Limited Human Research Ethics Committee) was obtained to administer the survey. We are also grateful to NSW Education Standards Authority for providing administrative enrolments data. Our code and the survey questionnaire are available in the online supplementary information accompanying this paper.

Footnotes

We distinguish between Economics (the Year 11 and 12 subject) and economics (the field) throughout the paper by capitalising the former. [1]

For example in New South Wales, the Year 11 and 12 Business Studies syllabus touches on exchange rates and interest rates in the context of businesses' financial management strategies, and economic conditions as a factor affecting consumer choice (Board of Studies New South Wales 2010). Standard Mathematics covers financial mathematics skills, which cross over with economic concepts, such as interest rates (NSW Education Standards Authority 2017). In Years 7 to 10, students may have an introduction to economics through the Commerce elective (NSW Education Standards Authority 2019); this is an avenue by which students may gain basic economic literacy, though the economics component has only become a core part of the elective since 2019. [2]

Schools deemed out of scope included distance education providers, TAFE (an Australian vocational education and training provider), international school campuses and schools without enrolment figures. Approvals were not obtained from the Catholic education office for all dioceses, and therefore 19 schools had to be excluded from the population. [3]

All 770 schools in the sampling frame were given the opportunity to participate in the survey (i.e. were sent a pre-approach letter, followed by a recruitment phone call). A total of 90 schools were recruited, with 51 completing the survey. Fourteen schools expressed a willingness to participate but were unable to do so within the allocated fieldwork periods and 25 schools declined to participate post-recruitment. The most common reasons for declining post-recruitment included being unable to find a teacher to facilitate the research, or students being bound by other commitments that prevented completion within the specified fieldwork period. [4]

The average time taken to complete the survey was 10 minutes. [5]

The analysis uses an ‘imputed sex’ variable (male/female) for respondents who reported non-binary genders or preferred not to identify their gender, to be consistent with the enrolments data (which are in terms of male/female). While the student survey asked about gender, the sample size for non-binary genders or those who preferred not to identify their gender was too small to run separate analyses. [6]

The hypotheses generated from previous RBA analysis and liaison were too expansive to explore in a questionnaire. Furthermore, it was possible that some factors had yet to emerge. Groups were also used to glean any specific language used by students. [7]

At the time of completing the survey, however, about a third of Year 10 students had already selected their subjects and 85 per cent had already started the subject selection process. [8]

The administrative data available do not allow us to identify schools where Economics was offered but not taught due to a lack of student demand. We instead take Economics being taught (at least one Economics student enrolled) as a proxy for Economics beings offered. [10]

In matching the school-level information to the survey dataset, it was necessary for the HSC cohort size and number of subjects taught variables to be collapsed into 5 categories to prevent identification of individual schools in the dataset (a requirement of the ethics approval). [11]

When we exclude the variable that controls for number of subjects, the results are qualitatively similar. [12]

The importance placed on ATAR scaling relates to students' responses to what they consider when selecting subjects in general; see Livermore and Major (2020) for more details on factors students consider when selecting subjects. The results are also robust to the inclusion of controls for the other subjects studied. [13]
