TJHSST Semifinal Round

Out of the students who apply to Thomas Jefferson High School of Science and Technology, about one third pass the first round November admissions exam and take the SIS/Essay test in February. For the Class of 2022, over 3,000 students — a number predicted to increase — applied and about 1,100 students were semifinalists. Of those, only 480 are admitted each year.

In order to stand out from the crowd, Principia’s TJ SIS/Essay classes focus on telling your unique story and on writing in a clear, concise, and logical way. We’ll cover the importance of structure, grammar, and concision as well as implement time management strategies including outlining, revising, and proofreading.

Principia offers TJ SIS/Essay classes over the summer and in the winter after the first round exam.

The SIS (Student Information Sheet)

Contrary to its name, the SIS is not a simple form that students fill out. The SIS involves 3 personal questions that are intended to reveal the applicant’s experiences, interests, and goals. Each response is limited to 1650 characters.

In our students’ essays, we encourage incorporating both self-reflection and future aspirations, connecting past experiences and career goals that coincide with TJ’s own mission and beliefs.


The Problem-Solving Essay

Officially, the TJ Admissions Office calls it a “problem-solving essay,” which consists of a math or science problem or a combination of both. We prepare our students for all possibilities; either way, it’s one essay with a maximum of 3700 characters.

One thing to keep in mind: TJ has already tested your math and science knowledge in the first round exam. What they’re looking for here is not only your ability to solve a problem but the ability to clearly explain your thought process and to demonstrate knowledge on a deeper level, making real-world connections and ethical considerations.

Teacher Recommendations

In addition to the SIS/Essay test, semifinals must also submit two teacher recommendations — one 7th or 8th grade math or science teacher and one 7th or 8th grade teacher of their choice.

According to the Admissions Office, “The form asks the teacher to reflect on his/her experience with you in the classroom, whether an applicant has particular traits important to the mission and goals of the school, and how an applicant may contribute to the learning environment at TJHSST.”
