About Thomas Jefferson School

Welcome to Thomas Jefferson School (TJ), an international coed boarding and day school community for grades 7 to 12 located in suburban St. Louis, Missouri. Our core classical liberal arts curriculum appeals to students from St. Louis to Shanghai, Little Rock to Nowy Sacz. We are a community of diverse minds aspiring to the highest standards of scholarship. 

Our Mission

Thomas Jefferson School gives its students the strongest possible academic background through a classical education. Within a nurturing community, students develop a responsibility for their own learning and a desire to lift up the world with beauty and intellect.

The Best Choice for College Preparation 

Since 1946, Thomas Jefferson School (TJ) has provided students the best environment in which to develop true intellectual depth. We provide an unparalleled program that emphasizes community and responsibility and holds students to high expectations in every area of school life.

TJ students are truly diverse and can’t be categorized as any particular type. They share energy, independence, a passion for learning, and a commitment to preparing for college. TJ students connect with others who have the same desire to learn. TJ is truly a second home.

The formative teenage years are a critical time for developing cultural awareness and analytical thinking. The liberal arts, ideally suited for this time in life, give young people an education that is never out of date.

TJ students are remarkable. We consider it a privilege to work with them. Their impressive college-placement record is a result of their natural ability and their learning experience at TJ.
