Trinity Lutheran Classical School, as an educational service of the Trinity Lutheran Church LCMS congregation, accomplishes the mission of the congregation. The congregation's mission is to preach and teach God's Word, confess the faith of the Book of Concord, and live in faith toward God and in love toward one another.

Trinity follows a long tradition of Lutheran Schools that provide excellence in education. Trinity uses a Classical approach to education which strives for academic excellence, behavioral discipline, Christian content, and direct instruction methodologies. Classical Education is based on the understanding that a child develops intellectually in different ways at different ages of their life. Therefore, his/her education should correspond to the different stages of his/her intellectual development. All subjects are taught using a variety of textbooks and methods, but teachers strive to teach everything from a Christian viewpoint.
