Students experiencing difficulties in learning in regular classes and sitting examinations regardless of the cause, are supported through Learning Support. It includes support for students with significant learning difficulties, mild intellectual disabilities, language disorders and behaviour needs.

Students do not need a formal disability diagnosis to access support through these resources, including students with autism spectrum disorders or mental health disorders who have lower level needs.

The Learning Support faculty at Xavier High School also oversees the educational needs of English as a Second Language (ESL) students, students of Language Backgrounds Other Than English (LBOTE) and students on the Catholic Aboriginal Support Assistance Program.
