There are no official statistics published by the Irish government about the performance of secondary schools in Ireland.
It is hard to compare schools without any data to use . The Sunday Times (Irish Edition) usually compile a League Table of schools based on the numbers of pupils getting into Third Level courses.
It's not an ideal method of comparison - but until teachers and the government agree on publishing exam results it's all we have.
Here are the top 20 "Best" Schools in Ireland - based on the percentage of final year pupils getting a place at University. The figure on the right is the percentage of students getting a place at Universty in 2014
