During the 1978-79 school term, Jackson Christian sought accreditation through the Southern Association of Colleges and Schools. The self-study was conducted by the faculty and administration in the fall and then evaluated by a visiting committee from the Southern Association. Accreditation was awarded to the school in 1979 making Jackson Christian the first SACS accredited school in Jackson, Tennessee.

In the fall of 2009, Jackson Christian decided to add another layer of accreditation credibility from the National Christian School Association. The National Christian School Association (NCSA) established the Accreditation Commission over 30 years ago. The mission of the Commission is to establish and maintain academic and spiritual standards that are designed to produce high-quality, Christ-centered education on the pre-college level. In partnership with Cognia (AdvancEd), NCSA is able to provide joint accreditations that are nationally and internationally recognized to all our member schools.

In the fall of 2017, Jackson Christian sought to receive STEM certification from Cognia (AdvancEd). Completing the standards and producing evidence of excellence in STEM initiatives, Jackson Christian was recognized in 2018 as the first independent school in Tennessee to achieve STEM certification.
