Marian School, the primary section of St Mary's School for Deaf girls, is situated in the grounds of Dominican Convent in Cabra, Dublin 7. This modern purpose built school was officially opened in 1988 and caters for pupils aged four to fourteen years.

Children are admitted following an assessment by a team of medical and educational professionals. There is an ongoing assessment procedure to ensure that the students are making satisfactory progress.

The classrooms are equipped with either a group or radio aid system. This ensures that the students are exposed to amplified sound during the school day. Outside school the pupils wear individual hearing aids.
