In May 1995 the Oklahoma State Legislature passed, and the Governor signed, Senate Bill 479 which says in part,

Private and parochial schools may be accredited and classified in like manner as public schools, or, if an accrediting association is approved by the State Board of Education, by procedures established by the State Board of Education to accept accreditation by such accrediting association, if application is made to the State Board of Education for such accreditation.

In October 1995 the Oklahoma State Board of Education approved the application of the Oklahoma Private School Accreditation Commission to oversee the work of individual private school accrediting agencies. Subsequently, several accrediting agencies petitioned OPSAC for approval.
