Diverse Student Body:
Our students are truly diverse and can’t be categorized as any particular type, but they share common denominators – energy, independence, an interest in their own education, and a commitment to using their teenage years wisely to get ready for college and adulthood.

Here, they connect with others who have the same desire to learn. TJ is their second home.

Academic and social life being intertwined at Thomas Jefferson (TJ), teachers and students form bonds that extend beyond the classroom.

Our students’ admiration of and respect for their teachers derives not only from the faculty’s skills within their disciplines but also – and especially – from every teacher’s devotion to every student’s growth and success. Like capable parents, faculty members support and encourage students even while holding them accountable.

At Thomas Jefferson (TJ), boarding students from all over the U.S. and all over the world will form lasting friendships with their local peers. Likewise, day students will share space in the dorms and learn how to manage living with others – great practice for college.

If you are an American student, perhaps a classmate will invite you abroad, or if you are an international student, maybe you’ll be invited to spend part of a school vacation here in the heart of the United States.

The rooms at TJ, situated in cottages with their own outside doors and private baths (but with teachers around the corner) promote structured independence.

Boarding life makes TJ look more like a relaxed liberal-arts college than a regimented American high school. After the business-and-dress-code part of the day (the mornings with the academic solids), the casually attired afternoon schedule includes labs, sports, extracurricular activities, study halls (for younger students and students in grade trouble), and some more unscheduled time that you get to manage on your own.

Activities:
In the evenings and on weekends, a teacher or a resident assistant circulates on campus with a cell phone to help students focus on homework, enforce in-room times, and provide an adult presence.

If you get into grade trouble, your adviser (a teacher) will quickly intervene to put you in study hall or to develop a personal schedule for you or to make you seek out tutoring. If you’re in good academic standing, however, you have learned to manage your time well – which is exactly what college requires.
