Since 1971, HKIS has been continuously accredited by the Western Association of Schools and Colleges (WASC), an American accrediting organization covering California and the Pacific Rim. Accreditation is renewed with WASC every six years through a yearlong process of self-study analysis, and a visit and final report by a team of educators from the United States and Asian international schools. Improvement plans based on the findings of the school and the visiting team are folded into HKIS’s strategic and operational plans.
