On 8 April, 2016 enrollment was over 1000 students(with a roughly 50:50 ratio of boys and girls, aged 12 to 18) and a teaching staff of more than 70.[2] As of 2024, these numbers have increased to over 1200 students and more than 80 staff.[1]
The school operates the Transition Year, the Leaving Cert Applied, and the Leaving Cert Vocational Programs. Students also pursue programs in physical education and religious studies.[citation needed] Adult education is promoted at Scoil Mhuire, which is one of the largest adult education schools in the country.[1]
