This paper focuses on two aspects of gender inequality in Irish higher education: inequality in participation by gender and inequality of performance by gender, institution and subject. We use a rich set of data from the Higher Education Authority of Ireland which detail inter alia enrolment in institutions of higher education--Universities and Institutes of Technology--and record the class of degree received by graduating students, by subject and gender. The first aspect was the participation of women. Although more women enrolled as full-time undergraduates in universities than did men, the reverse was the case in the Institutes of Technology. This had much to do with the subject structure of universities vis-à-vis the Institutes of Technology in tandem with the subject preferences of women and men. The second issue was inequality in performance. A major conclusion of this paper is that "after" enrolment there was little difference between the success rates of women and men in receiving first-class degrees in the different subjects but there was considerable difference between the institutions.
