The Senior School begins in Transitus (equivalent of Primary 7) and the essential philosophy is to offer all pupils the opportunity to follow a broad curriculum designed to provide challenge and stimulation, and which includes a wide range of academic subjects which are available right through to Advanced Higher level. Time is also allowed for Personal and Social Education, Religious Education and Physical Education.

Pupils are known and recognised as individuals and genuinely small class size throughout the School affords the opportunity for the academic needs and aspirations of each individual pupil to be met and usually surpassed, and for them to become successful in their learning. The small environment also allows each pupil a greater opportunity to make a significant and effective contribution to the wider life of the School, allowing each to develop self-confidence and responsibility in addition to academic success.
