The main building is purpose-built. Accommodation for senior school students was enhanced by the acquisition of the Convent House in 1991.
In order to deliver the needs of the modern secondary school curriculum, the school has a number of specialist rooms - for the sciences, information technology, and art. The school also has a hardcourt area and a playing field.
The school caters for the whole age range of compulsory education and, in addition, has a kindergarten and reception class for 4 year olds in the junior section. There is a growing Sixth Form in the senior section.
Pastoral care is the concern of all staff but especially of form tutors.
St Gerard's has a broad intake but no special needs provision
The two inspections carried out in recent times (1994, 2001) have spoken highly of the happy, secure environment, the effective learning atmosphere and the exemplary behaviour of pupils.
The school operates both an anti-bullying policy and a complaints' procedure, copies of which are available from the school secretary on request.
