Thomas Jefferson School (TJ) is a co-educational, non-sectarian, independent boarding and day school located in suburban St. Louis, Missouri. We educate a purposefully diverse and deliberately sized group of academically talented students spanning grades 7-12.
In our tight-knit, nurturing community, students embody our mission by "developing a responsibility for their own learning and a desire to lift up the world with beauty and intellect."

At TJ, Learning Goes Beyond the Classroom
Read MoreAt TJ, we strive to give our students an awareness of the larger community beyond their school and their individual social circles. To that end, all students complete a required number of service hours by the beginning of their senior year, and TJ's annual All-School Service Learning Day provides an opportunity for students along with faculty and staff to join in acts of service together. By helping others and participating in activities that do not provide monetary rewards, students gain a sense of responsibility for themselves and for the world in which they live. -
