Please note: ISSEA is not currently open for general applications. Membership is limited and spaces are only made available if an existing vacancy arises. Should a space become available, ISSEA will open the process to interested schools via a formal tender announcement.

Unless such a vacancy is announced, the membership process remains closed.

When the application process is open, schools interested in joining ISSEA must follow the formal two-stage approval process, beginning with the submission of an application form and a letter of intent endorsed by the Head of School by the stated deadline.
