Trident Academy began as a Saturday-only tutorial program in a Charleston area church room. The program quickly became recognized for its value in educating students with reading, spelling, and math difficulties, thus initiating the incorporation of the school in 1972.

With the help of the founding families, Trident Academy received guidance from notable individuals and organizations, including Dr. Lucia Karnes. Dr. Karnes studied directly under June Orton and her husband, Dr. Samuel T. Orton, a pioneer in learning differences research. Trident Academy was also involved in the beginning stages of forming the Orton Society, now known as the International Dyslexia Association.

The College of Charleston and The Citadel subsequently developed a Master of Arts in Teaching Special Education program to help further educate Trident Academy teachers in learning differences education. Trident Academy has aligned with Orton-Gillingham International to provide teacher training and instructional resources.

Trident Academy admits students of any gender, sexual orientation and identity (including transgender status), race, color, religion, national and/or ethnic origin, and provides students with all rights, privileges, programs, and activities generally accorded or made available to students at the School. In accordance with applicable law, it does not discriminate in the administration of its education policies, admission policies, scholarship and loan programs, and athletic and other school administered programs. Similarly, Trident Academy prohibits unlawful discrimination based on disability. However, consistent with Trident Academy’s mission, it is the admission policy that to qualify for admission consideration, students must have diagnosed learning disabilities and/or certain communication disorders and meet certain threshold criteria as evidenced by their professional testing documents.
