There are a limited number of spaces in the English as an Additional Language (EAL) Program for students who meet the qualifications for admission. Learning support is available for students who function well in the classroom but have some learning differences.

All applications are considered on a case-by-case basis.

The Head of School reserves the right to accept, or not, any application for admission based on space availability and the degree to which Seisen’s educational program can meet the identified needs of the applicant.
