What did abolishing university fees in Ireland do?

University tuition fees for undergraduates were abolished in Ireland in
1996. This paper examines the effect of this reform on the socioeconomic
gradient (SES) to determine whether the reform was
successful in achieving its objective of promoting educational equality. It
finds that the reform clearly did not have that effect. It is also shown
that the university/SES gradient can be explained by differential
performance at second level which also explains the gap between the
sexes. Students from white collar backgrounds do significantly better in
their final second level exams than the children of blue‐collar workers.
The results are very similar to recent findings for the UK. I also find that
certain demographic characteristics have large negative effects on
school performance i.e. having a disabled or deceased parent. The
results show that the effect of SES on school performance is generally
stronger for those at the lower end of the conditional distribution of
academic attainment.
