SEE HOW TJ WORKS VISIT TJ

Our students don’t wait for answers.


At TJ, much of your learning happens through discussion. A book, math problem, or experiment might get things started, but you won’t spend class just listening. You’ll ask questions, disagree with a classmate, change your mind, and sometimes come up with the idea that gets everyone talking.


That continues through Outside Reading, or O.R. You tackle assigned reading on your own and write about it several times each week. Your teachers write back, helping you see what you’ve figured out and where you might be stuck. As the work gets harder, you begin to see how much you can do with it.


You get used to being asked, “Why?” and soon you’re asking it yourself. Having your own ideas is only the beginning. The fun is discovering how far you can take them.


 

 
 
Class ends. The conversation continues.
 

Serious work. Real ownership.


 

At most schools, every hour is accounted for. The schedule tells you where to be and the teacher tells you what to do. Then it’s on to the next class.


 

Classes at TJ don’t fill your entire day. Between them, you’ll have time to get your work done, meet with a teacher, spend time with friends, or dig into something that interests you. 


 

As you get older, you decide more of what to do with that time. You’ll learn to manage what’s expected of you while making time for the things that make school enjoyable. 


 

It comes down to a question most schools don’t give you much chance to answer: what do you do when it’s up to you? 


 

LIFE ON CAMPUS


 

The Thomas Jefferson difference

We are a

 
Home for Many Worlds
 

A small school can contain a surprising amount of the world. Your classmates may have grown up in St. Louis, Seoul, Nairobi, or Shanghai. You get to know people whose lives and experiences may be very different from your own.

 

Before long, those differences are simply part of everyday life. You discover what you have in common and how differently someone else can see the same thing. Here, a different perspective might be your roommate, your lab partner, or the person sitting next to you at dinner.

 

OUR COMMUNITY

 

A student at Thomas Jefferson School
At TJ, your report card tells you how you've grown, not just how you scored.


 

Teachers don’t just grade. They observe. Every term, in every class, you receive written feedback about the progress you’re making and where you still have room to grow. Your advisor brings those observations together, giving you a fuller picture of your experience at TJ.


 

Then you sit down together and talk it through. Not just the grades, but what has changed since the last time, where you might be getting stuck, and what comes next. After years of these conversations, you know yourself better as a learner. You know what challenges you, what helps you move forward, and when to ask for help.


 

By the time you’re thinking seriously about college, you’ve already spent years thinking about how you learn and who you’re becoming.


 

Parents see the difference, too. When we ask families what stands out about communication at TJ, our quarterly grade letters and the close relationships between faculty and families come up again and again.

STUDENT'S VIEWPOINT

“It is really cool to have a teacher recognize you for your hard work, and not just give you a letter grade, but express how well you did a specific project in their class.”

Every good thing at TJ starts with a conversation. We'd love to hear what brought you here.
