This paper considers the factors that impact on student success in first year science mathematics courses at the National University of Ireland Maynooth (NUI Maynooth). These factors include previous performance in the subject, attendance at lectures and tutorials, the number of assignments submitted, and attendance at the Mathematics Support Centre (MSC). The results of this initial study will be used to identify behaviour patterns that lead to successful completion of first year courses. The findings will help mathematics departments to target support initiatives in areas which are most likely to improve student learning. (Contains 1 table.)
