Previous research has indicated significant variation between schools in the proportion of their students who go on to higher education. However, relatively little attention has been paid to the specific school characteristics influencing application and entry to tertiary education. This paper sets out to analyse the individual and school factors which influence the transition to higher education in the Irish context. The paper draws on a large-scale study of 4,400 students within 108 secondary schools in the Republic of Ireland. Almost three-quarters of the students in the sample applied for a higher education course. However, schools varied in the application rates of their students. These differences are found to be related to the background characteristics of students (in terms of gender, social class and prior ability) along with the institutional habitus of the school. It is found that school factors associated with increased college application rates do not necessarily appear to yield higher rates of college entry but rather that successful entry to tertiary education is related to general academic effectiveness in the school.
