St Louis High School is very committed to providing students with the opportunities to study STEM subjects.

Science is a compulsory subject in Junior Cycle and then students can choose to study Biology, Chemistry and Physics up to HL in the Leaving Certificate. Applied Maths is also offered. Maths is offered up to HL in the Leaving Certificate with a high number of students taking this subject at this level. We encourage our students to participate in the BT Young Scientist Exhibition and also in SciFest, where we have met with great success over the years.

IT is provided as part of the Wellbeing programme in the Junior Cycle and students have the opportunity in Transition Year to experience the world of Coding.

Whilst Technology is not offered currently in Leaving Certificate cycle, it may be introduced in the coming years.

Many of our students have been successfully involved with the Trinity Walton Club.
