Thomas Jefferson School (TJ) is a co-educational, non-sectarian, independent boarding and day school located in suburban St. Louis, Missouri. We educate a diverse and deliberately sized group of academically talented students spanning grades 7-12.
The best way to get to know TJ is by spending time on campus, meeting our students and experiencing our classes. See our community for yourself at one of our open houses, shadow days, or let us create the perfect visit just for you.
