St. Theresa Catholic School is fully accredited by the Florida Catholic Conference and recognized by the National Council for Private School Accreditation. The Florida Catholic Conference Accreditation Program was adopted by the Florida Bishops during the 1970-1971 school year. This program was developed by state diocesan educational leaders in consultation with school pastors and principals.

The standards of this accreditation program are derived from sound educational research and influenced by Catholic educational philosophy which integrates faith and values with life and learning. These standards assist schools in working through a dynamic self-evaluation process which promotes accountability and on-going excellence. Further, these standards, by serving as a basis to ensure quality in the schools, justify the faith that parents and others have placed in them.
