Trinity School caters for pupils between the ages of 11 and 19 and currently has approximately 1025 students on roll, including 108 in the Sixth Form.

Shaw House originally formed part of the school however it is now managed by West Berkshire council and is used as a conference venue and public attraction.

In September 2015, a new ASD Unit was opened, a 25 place local authority resource for students on the Autistic Spectrum.

When pupils join Trinity School they are placed in one of four houses,: Dragon (blue), Griffin (yellow), Pegasus (purple) and Phoenix (green).

This resource caters for students who have an Education and Health Care Plan (EHCP) for Autism Spectrum Disorder and, without specialist intervention would struggle in a mainstream school.
