Welcome from the Director of Admissions
Thank you for your interest in Thomas Jefferson School (TJ)! Our internationally recognized boarding and day school is home to a wide array of students, faculty and staff. We like to think of ourselves as a small place that thinks big. TJ students are bright, capable, and enjoy learning. Intelligence is definitely a good thing here!
Extraordinary things happen in our campus community. Our day and boarding students find this the kind of place where anything is possible. We do our best to help students learn about themselves just as much as they learn in the classroom. Words you will hear around here quite a often are Challenge, Independence, and Community. These are all traits we want our students to learn and know. View our Student Prospectus to learn more.
Since 1946, TJ has delivered the best in a liberal-arts, college preparatory curriculum, and as such, our students consistently score in the top 2% of SAT scores nationwide. Our track record of excellence consistently sets us apart from peer day and boarding schools. Students and faculty interact in and out of the classroom and our small class sizes foster an environment where class room discussions are encouraged and expected. Clubs, organizations, sports, and many other activities help our students become leaders. Excellence is our motto, and our aspiration.
I value your interest in our school, and appreciate the time it takes to participate in our admissions process. I look forward to getting to know you, and invite you to get to know us by scheduling a tour of campus and/or attending one of our Open Houses (October 25, 5-7pm | November 15, 10-noon). If you haven't already done so, please submit an inquiry to ensure that you will receive our admissions event communications. See the school in action by liking us on Facebook at or on Instagram.
Again, thank you for your interest in TJ! I cannot wait to get to know your family.
Erin Walsh, Director of Admissions and Communications
