Full membership is open to any individual who is the head of an independent UK school which educates girls within a single-sex environment for all or part of the 4-18 age range. Your school must be fee-charging, in all or in part; your governing body must be a member of AGBIS; and you (the Head) must be a member of ASCL or NAHT.
NB. GSA carries out accreditation visits for all prospective members and requires you to provide an inspection report. It is a condition of membership that you attend the New Heads’ Induction course. If you are the Head of a diamond school, when you become a member whoever is in charge of girls’ education in your school is eligible for complimentary membership.
