The Western Association of Schools and Colleges (WASC), a 501(c)(3) organization, is recognized as one of six regional associations that accredit public and private schools, colleges, and universities in the United States.
  
The Western region covers institutions in California and Hawaii, the territories of Guam, American Samoa, Federated States of Micronesia, Republic of Palau, Commonwealth of the Northern Marianas Islands, the Pacific Basin, and East Asia, and areas of the Pacific and East Asia where American/International schools or colleges may apply to it for service.
 
In June 2007, Escondido Charter High School was granted a six-year term of accreditation with a midterm review by the Western Association of Schools and Colleges (WASC).
 
In February 2010, a two-member WASC team visited our campus and met with school leaders and teachers. They concluded that ECHS had made significant progress in implementing the School-wide Action Plan. The term of accreditation was extended to June 20, 2013.
