TEPSAC helps ensure quality in private schools by monitoring and approving organizations that accredit the various non-public elementary and secondary educational institutions in the state of Texas.

The State Commissioner of Education recognizes the Texas Private School Accreditation Commission and its affiliated non-public schools. Since 1986, the Texas Education Agency, through the Commissioner of Education, has recognized the accreditation responsibilities of TEPSAC and its affiliated associations. (Subsequent to the establishment of TEPSAC, direct accreditation of non-public schools by the Agency was phased out and was discontinued after 1989.)

The relationship of TEPSAC with the Commissioner allows for the following activities related to accredited non-public schools:

• transferability of student credits earned in accredited nonpublic schools to Texas public schools as permitted by Texas Administrative Code, Title 19, Part II, Chapter 74.26 (a) (2)
• recognition of teacher service in accredited nonpublic schools for salary increment purposes in Texas public schools, as authorized in the Texas Administrative Code, Title 19, Part II, Chapter 153.1021(h)(8)
• acknowledgment of all accredited elementary and secondary nonpublic schools in the Texas The listing of all accredited non-public schools in the Texas School Directory

TEPSAC meetings held biannually with Agency liaisons to ensure the ongoing integrity and quality of the process.
