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. 

What our students have to say

More from Maria and Justin:

“I truly didn’t believe that I would actually have a chance to come from Poland to Thomas Jefferson School in the first place, and when I got the news, I was really happy, but then a bit scared. When I finally came, everyone was so nice and I knew I would have a lot of fun with my roommate because of the way she approached me, as a bit crazy but super-nice and positive person. I was also a bit scared of classes that are taught in English, which isn’t my native language. I didn’t expect that I would adapt to this place so quickly, but TJ is a place where everyone feels comfortable and safe. Coming here gave me the opportunity to experience a lot, expand my language skills and make friendships that will hopefully last for a long time.”

“TJ continuously astounds me in its dedication to the student. The teachers treat you and teach you like you know something, and that quality facilitates the magnificent education I am receiving. The students are even better: any person can walk up to a TJ student and have a thought-provoking, stimulating, and intelligent conversation with them. There’s nothing better than a community like TJ’s.”

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.
