Heritage Covenant Schools operates legally in the state of Tennessee by virtue of its membership in the Tennessee Alliance of Church Related Schools. Membership in TACRS in no way denotes state control of Heritage Covenant. The school is exempt from state accreditation and does not refer to itself as being accredited.

Heritage Covenant is classified by the Tennessee State Department of Education as a Category IV, Church-Related School, Exempt from Accreditation.

Because HCS is not accredited, students transferring to an accredited or public school from Heritage Covenant Schools may be required to take pre-placement tests. Graduates of Heritage Covenant High School are generally not affected by the accreditation status and are accepted at colleges and universities. However, students who score below average on ACT or SAT college entrance exams may be required to take the GED before admission.

Heritage Covenant graduates have been accepted at nearly every major university in the Southeast as well as the United States Military Academy at West Point and the Juilliard School of Music in New York.
