St. Thomas Aquinas Catholic School is a fully accredited elementary/middle school with approximately 320 students in Pre-K - 8th grade, with two classrooms per grade. The school provides an environment rich in academic, spiritual and emotional learning.

The school day begins at 7:50 a.m. and ends at 2:10 p.m.

The curriculum consists of a basic course load designed to provide an effective foundation for higher learning. With a strong focus on language arts, math, and science, the curriculum also integrates religion, humanities, history, and foreign languages into the daily routine. In addition, physical education, art, and computer science classes are spread throughout the week. Upper grades are departmentalized, with an advanced track in the math department. Kindergarten students participate in a full school day comprised of a highly successful phonics based pre-reading program, an introduction to math concepts, simple science units, field trips, music, art, and religious education. Kindergartners are promoted to first grade with a high level of reading readiness. In recent standardized tests, including the Iowa Skill Tests, our students scored well above the national average. St. Thomas Aquinas graduates are accepted and excel at the most respected high schools in the area, including: Convent of the Sacred Heart, Fairfield Prep, Greens Farm Academy, Hopkins, Lauralton Hall, Notre Dame of Fairfield, Notre Dame of West Haven, Regis, St. Joseph High School, Sacred Heart Academy, and the Fairfield, Easton, and Westport public high schools.
