III. Major Events

WASC and IB visit schools on a five-year cycle. In anticipation of the last visit in February of 2013, we underwent an 18-month self study. A comprehensive report was published including recommendations from the visiting committee. Below are the 2018 WASC / IB (PYP, MYP, DP) reports. We also completed a substantive change report with WASC after the Kwansei Gakuin Educational Foundation merged with the Senri International School Foundation, and we started our international boarding program, the Global Futures Program:
