Higher education inequality: do graduate outcomes differ by socioeconomic status?

In earlier posts in this series on inequality and higher education, I have suggested that the SES participation differences are largely driven by prior academic performance and that different SES groups seem to experience higher education in much the same way, but low SES students are less likely to complete their degrees. In this post, I will look at outcomes for the students who do complete their degrees.

First, are there differences in rates of getting a job? The 2017 Graduate Outcomes Survey finds that there are small differences. About four months after completing their bachelor degree, 73.6 per cent of high SES graduates who were looking for full-time work had found it, compared to 70.3 per cent of low SES graduates. However, of those who were working full time low SES students were slightly less likely to report not fully using their skills at work than high SES graduates (27.1 per cent compared to 28.9 per cent). It is difficult to say whether there is any direct SES effect in these results, as employment outcomes differ substantially by field of education, and SES differences in discipline choices could explain the results.

The Graduate Outcomes Survey also looks at starting salaries in the first full-time job after completing an undergraduate degree. Again, we find a small SES difference: the median starting salary for high-SES graduates in 2017 was $61,000, and for low SES graduates it was $60,000. This does not tell us whether there is any direct SES effect (such as not being able to access social networks to find professional jobs) or whether other factors such as discipline explain the result. A study using an earlier first year out survey had a limited control for discipline, as well as controls for weighted average marks, gender, and various other factors. It found no negative salary effect for low SES students, using a geographic measure of SES.

One possible cause of SES differences is that low SES students tend to attend the less prestigious universities, reflecting the school results issues reported in an earlier post. For example, 7.5 per cent of the University of Sydney’s students are low SES on a geographic measure, compared to 26.2 per cent of Western Sydney University students.

In theory, university attended should affect starting salaries. There are well-known differences in entry requirements between universities, which employers may take as a more reliable measure of ability than university marks, and employers may assume that the more prestigious universities have better teaching (can attract better staff, have more to spend – although student satisfaction surveys don’t support this conclusion). The first full-time job is when employers have to make greatest use of proxy indicators of potential, since most new graduates lack a track record in full-time skilled employment. Consistent with this, nearly 40 per cent of graduate employers say they have preferred institutions, mostly Group of Eight universities.

In practice, however, many studies have found no or small starting salary differences by university or university grouping (eg here, here, here, here and here). What course you take matters much more to your income than what university you attend. Read More »
