Welcome to TCA

Trinity Christian Academy is a University-Model School in O'Fallon, Missouri.


University-Model schools become the educational solution for many parents because they combine the best attributes of home schooling and traditional Christian education.

Students attend school two or three days per week, where they receive the academic expertise of accredited teachers and the social environment and structure of a school. On other school days students complete assignments in their “Satellite Classrooms” under your character-building influence.

University-Model Schools provide a quality, cost-effective, college-preparatory education. Please refer to the National Association of University-Model Schools website for more information.


At Trinity Christian Academy, our goal is to deepen faith, build character and develop strong academics.


In our small classes, your child will be nurtured and encouraged to develop his or her unique learning style.

Who attends TCA? 

  • Home-schooling families interested in the university-model so their children can attend classes and work at home

  • Families who want to disciple their children without the full home-school load

  • Families who want to train their children to think with a Biblical worldview and a rich classical knowledge

  • Christian families looking for a more affordable option
