Catholic School Inspection (CSI) previously named "Section 48 Inspections", conducted under Canon Law and Sections 48/50, aims to report to and advise the Diocesan Bishop on the quality of religious education and the Catholic life of the school. It also informs parents, carers, and the wider community about the school’s religious education standards and celebrates its role as a Catholic community. Inspections are carried out by nationally trained inspectors from the Catholic Schools Inspectorate.

There are three judgement areas:

• Catholic Life and Mission
• Religious Education
• Collective Worship

Sacred Heart was inspected in June 2026 and was judged 'outstanding' overall.
