(TEPSAC). TEPSAC is a confederation of accrediting associations, of which ISAS is a member. TEPSAC’s primary purpose is to maintain standards of accreditation among its membership. These standards of accreditation are comparable to Texas Education Agency (TEA) standards and preserve the integrity of the member organizations and the schools they accredit. 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 such as the Independent School Association of the Southwest. St. Clement’s Parish School has been accredited by ISAS since 1984.

, dedicated to serving our Lord and Savior Jesus Christ by spreading His Gospel, and by teaching the history of mankind in relationship to God and His creation in a Christian community. Each student is recognized as a unique child of God.
