Rodney and Frances Duron, parents of the current chancellor, Denny Duron, founded the school in 1980 as a small kindergarten to eighth grade school. Their vision was to establish a school that would offer families of Shreveport an affordable private school, a school that welcomed a diverse student population and a school that stressed excellence in academics, the arts and athletics. The high school was added as a second campus in 1989. Evangel has grown from 21 graduating seniors in 1990 to over 100 seniors in 2001. The school currently has approximately 600 students.

As of Spring 2005, Evangel Christian Academy is the only school in Caddo Parish, public or private, to have earned SACS accreditation for grades K-12th. Evangel Christian Academy is a state approved (K(5)-12) school through the Louisiana State Department of Education. It offers students of all ages a challenging curriculum, preparing them for higher education and for life.
