The Board of Directors of Pennsylvania Association of Independent Schools (PAIS) oversees the Commission for Accreditation . This Commission was formerly known as the Pennsylvania Association of Private Academic Schools, Inc. (PAPAS), founded as a non-profit association chartered by the Commonwealth of Pennsylvania in 1947, officially recognized by the Pennsylvania State Board of Education in 1948, and authorized to accredit school by the Private Academic Schools Act 1988-11. As a result of the merger of PAIS and PAPAS in 2006, PAIS is empowered by the Pennsylvania Department of Education to accredit private independent school in the state. Schools accredited by PAIS are accredited in lieu of licensure.
The PAIS Commission for Accreditation is recognized as a member of the NAIS International Commission on Accreditation. It has fully met the established criteria for effective independent school accreditation practices, exemplary standards, and models of successful accreditation policies and procedures - Criteria for Effective Independent School Accreditation Practices and is held accountable over a ten-year cycle to compliance, best practices, policies and procedures in the accreditation process. This serves two purposes: institutional improvement and quality assurance.
