Grace Preparatory Academy (GPA) is a private, college-preparatory Christian school located in Arlington, Texas, United States. Founded in 1992, it offers programs for Kindergarten through Twelfth Grade students drawn from the Dallas/Fort Worth metroplex. It is the founding member of the National Association of University-Model Schools and is accredited by the Southern Association of Colleges and Schools.

In the spring of 1992, a group of parents met to share their vision for a new model of education that blended the best of their individual public, private, and home-school model experiences. They incorporated the school on December 18, 1992; and held its first day of classes on August 16, 1993. In 2005, the National Association of University Model Schools (NAUMS) — which was founded as the outreach arm of GPA — became a separate entity, and GPA also became accredited with the Southern Association of Colleges and Schools (SACS).

GPA was the first to implement the educational model known as the University-Model School (UMS) which combines two elements of educational success, the professional classroom instruction of a teacher and the at-home mentoring of a parent, into a unified, college-like program. Students attend classes on campus two to three days per week, and instruction continues at home on the rest of the week.

GPA secondary students compete with other non-public schools in athletic and academic events as a member of the Texas Association of Private and Parochial Schools. Athletic teams include Baseball, Boys' Basketball, Girls' Basketball, Cross Country, Track & Field, Football, Golf, and Volleyball. Academic teams compete in Academic/Speech, Art, and Music. Extracurricular organizations include: Cheerleading, Journalism, Spanish Club, Fellowship of Christian Athletes, and Robotics Club.
