Keystone Schools completed the WASC (Western Association of Schools and Colleges) accreditation process in 2018. Its institutional quality was confirmed on international platforms. Once the WASC accreditation process is fully completed, Keystone Schools will be the only private school in Turkey to be internationally accredited. KIS will acquire the same institutional standards as the world's best universities — UCLA, Cal State, CalTech, UC Berkeley, and Stanford.
WASC is one of six regional accreditation institutions authorized by the American government to evaluate and improve the education quality of schools, colleges, and universities. WASC has included institutions in California, Hawaii, and the Pacific states since 1962. Having started to receive applications from higher education institutions outside the United States, WASC can include only those institutions that have passed a challenging qualifying process in candidacy status.
The accreditation process is carried out by a commission of independent experts, including experienced educators. In this process, it is evaluated that a student-oriented education approach has been established in accordance with the principles of "good management, self-development, and sustainability." Kilittaşı Schools meeting these standards demonstrates that the school is recognized not only nationally but also on a global scale.
Through accreditation, Kilittaşı Schools graduates receive an education held to the same academic standards as these world-class institutions
