Sacred Heart exists for the primary purpose of providing Catholic children from the parish of Thornlie with a Catholic Education.
Thus enrolment priority or preference is given to:
- Catholic students from Sacred Heart Parish.
- Siblings of Catholic students already enrolled in the school.
- Catholic children transferring from outside Sacred Heart Parish.
- Siblings of non-catholic students.
- Non-catholic students from other Christian denominations.
- Other non-catholic students.
