In every ranking, the first thing we need to address are the ranking criteria, i.e. publications, student numbers/member of staff, employability etc.
UL is ranked 1st in Ireland for employability of his graduates. The average in Ireland is around 65% and UL scores more than 70% according to the latest data.
Taking into account the good ratio of staff to students, around 1700 staff to 17.000 students and the relatively small classes (ratio of teaching staff to number of students per course), UL is scoring very well in many metrics.
