Mitcham Girls High School is a progressive learning community. It understands the need to evaluate its own performance regularly so as to bring about changes which benefit students.
In 2011, after an extensive consultation process, and review of teaching and learning processes, the school was accredited by the Council of International Schools (CIS).
CIS is a non-profit membership organisation which provides services to primary and secondary schools, higher education institutions and individuals that share these ideals:
To achieve this goal, our members must infuse their programmes and offerings with international and intercultural perspective so that students can move forward with the attitudes and understanding that will provide them with a solid base wherever their studies or work may take them. Primary and secondary school members must further commit to undertaking an ongoing external quality assurance process to enhance student learning.
