Located on one site in Ringwood East, the Early Learning Centre is co-educational, while girls and boys are educated in single-sex environments from Prep – Year 9.

Continued growth led to the need for larger and more modern facilities, and subsequently the school moved to its current campus of just over 50 acres (20 ha), at Ringwood East in 1953.

The schools facilities include a multi-function assembly and performance space, ELC, senior and junior libraries and information centres, science and technology laboratories, computer laboratories, established areas for visual and performing arts, a swimming pool and gymnasium complex and other sporting facilities.

The farm has been operational since the opening of the Ringwood campus of the school, and has since been very successful in local sheep competitions.

The Tintern Grammar houses are Butterss-Cross (after Agnes Cross, Headmistress 1911–1918), Gordon-Grant (after three former head prefects, all sisters), Mansfield-Mckie (after founder and first principal Emma Cook, whose maiden name was Mansfield), Somner-Stewart (after three sisters, two of whom were staff members) and Dann-Watt, after ex-student and Olympic Gold medal winning cyclist Kathy Watt.
