At the core of the Bishops academic system are two fundamental notions: first, class size is restricted to 28 except in special cases; second, staff are engaged in order to contribute to the teaching in just one subject, which means that they are able to devote their energies in just one direction and become even greater experts in their field. Where possible each staff member has his or her own dedicated classroom, fully equipped as the needs of the subject dictate, and serving not just as a teaching venue but as a subject-specific environment. This also means that members of staff are easy to find in the event of queries or a need for clarification or extra help.
