St. Philip Catholic School is accredited by the Texas Catholic Conference Education Department (TCCED) and recognized by the Texas Education Agency of the State of Texas.

The Texas Catholic Conference Education Department (TCCED)coordinates and supervises the accreditation of all Catholic schools in the State of Texas through the Texas Catholic Conference Accreditation Commission. The accreditation is reported to the Texas Private School Accreditation Commission (TEPSAC), the joint association established to review and approve the principles, standards, and processes of various accrediting associations. Nonpublic schools accredited by a TEPSAC approved association are recognized by the Commissioner of Education as accredited schools and are listed in the official Texas School Directory published annually by the Texas Education Agency (TEA). This acknowledgement ensures student credits earned in these accredited, nonpublic schools are recognized by the state of Texas and other educational institutions and that teacher service in these schools is recognized for salary increment purposes in Texas public schools. Accreditation of nonpublic schools under this arrangement became effective February 12, 1986. Accreditation of nonpublic schools directly by TEA ceased after May 31, 1989.
