Three schools maintain a perfect record
This year's Sunday Independent School League Tables supplement marks the first time Irish schools have been analysed over a 10-year period and compared in terms of the number of students they send to college or university.
Just three schools have maintained a perfect record over that period - sending all of their students on to third level since 2009.
They are separated, marginally, by the fact some schools send more students to university instead of colleges or institutes of technology.
Presentation College Cork has become the first school to retain its position as the top-ranked school in the country (in terms of throughput to college) since the Sunday Independent began compiling data on schools four years ago.
This year it has held on to the top spot it wrestled away from Limerick's Glenstal Abbey last year.
Since 2009 it has maintained the enviable record or sending 100pc of its school leavers on to third level.
What's more, 83pc of its students have been placed in a university over the past 10 years - with many of them choosing to progress to the nearby University College Cork.
Presentation College Cork charges day-fees of €3,900 and boasts of educating history-makers - its alumni include actor Cillian Murphy, journalist Fergal Keane and a host of rugby stars including Ronan O'Gara, Peter O'Mahony and former Ireland manager Declan Kidney.
Two Dublin schools have also maintained a perfect record over the past 10 academic years.
Colaiste Iosagain in Stillorgan has sent all of its Leaving Cert students on to third level since 2009, with 79pc of them securing a place in a university.
It is the country's best performing non fee-paying school in terms of throughput to college.
St Mary's College, Rathmines, has followed suit. The Dublin 6 school has sent 61pc of its Leaving Cert student on to a university.
Cistercian College on the Tipperary/Offaly border, and Mount Anville School, Dublin 14, have fallen just short of making the 100pc club. Both schools had maintained a 100pc record for nine years and last year succeeded in sending 94pc and 97pc of their students on to third level.
Christian Brothers College in Cork city has done well to maintain the county's strong record of academic achievement, sending almost 100pc of its students on to third level.
In all, are were more than 18 schools who sent at least 99pc of Leaving Cert pupils on to third level in the past 10 years.
