Scoil na Tríonoíde Naofa encourages the pursuit of excellence in academic study.  STN has a very good reputation for academic achievement and strives to ensure that the education provided continues to meet the ever-changing demands of our time.  We have an excellent teaching staff who set the highest of standards for behaviour and intellectual development.  We pride ourselves on our broad curriculum which ensures that each student has the opportunity to identify his/her strengths.

All Junior and Leaving Certificate subjects are offered initially at Higher level with the option of Ordinary level if the need arises.

First Year groups are not streamed. Classes are divided into equal mixed ability groups.  After First year, classes in Irish and Maths are divided in accordance with the levels taken by students.  Classes in other subjects remain mixed ability.  However, management reserves the right to stream in other subject areas if the need arises.
