The Association of Classical and Christian Schools (ACCS) accreditation measures how well schools are consistently implementing a Christian and classical philosophy of education throughout the entire school organization from school board oversight to classroom pedagogy, including student participation, conduct, and development, staff training, parent-teacher relations, operational and financial policies, community support, and the overall spiritual demeanor in the school classrooms. Accredited schools integrate Scripture throughout their school's curricula and demonstrate conformity with the Trivium in their teaching.

When schools are accepted as accreditation candidates by ACCS, they gain a partner who is committed to helping these schools improve through the accreditation process.

Regent Preparatory School is recognized by the Oklahoma State Department of Education.
