Understanding TJ Admissions.

Since 2021, TJHSST moved away from a single standardized test toward a holistic review. There's no one "TJ test" to cram for โ€” FCPS looks at academic performance, a problem-solving essay, and a student portrait sheet, with seats allocated across all FCPS middle schools.

๐Ÿ“‹

Holistic Review

No single admissions test. Students are evaluated on GPA, coursework, and a written application โ€” meaning consistent strong performance matters more than one test day.

๐Ÿง 

Problem-Solving Essay

A required essay where students work through an open-ended STEM problem, showing their reasoning process โ€” not just a final answer.

๐Ÿ—’๏ธ

Student Portrait Sheet

Teacher-completed ratings on problem solving, curiosity, and persistence โ€” built over years of classroom performance, not a single application.

๐Ÿซ

Middle School Seat Allocation

A portion of seats are allocated proportionally across FCPS middle schools, so being a strong applicant relative to your school's pool matters.

Everything the TJ application requires.

Strong math foundations are essential at every stage of TJ prep. But preparation goes deeper โ€” we cover all components of the holistic application.

๐Ÿงฎ

Advanced Problem Solving

AMC-style, competition-style, and TJ-style problems. Students learn to approach unfamiliar challenges with structured, logical reasoning.

โœ๏ธ

Experiential Essay

The essay that separates accepted students. We help students find authentic stories and write them with clarity and confidence.

๐Ÿ”ฌ

STEM Problem-Solving Essay

TJ's problem-solving prompt tests how students approach and communicate complex challenges โ€” a skill we develop over months.

๐Ÿ“š

Math Foundation Mastery

Pre-algebra through algebra โ€” built deep, not just memorized. Students who truly understand math perform better on every TJ component.

โšก

Speed & Accuracy Training

TJ-level problems require both mastery and efficiency. We train for speed with accuracy under real time pressure.

๐Ÿ—‚๏ธ

Student Portrait Sheet

We help students present their identity, interests, and accomplishments authentically and compellingly for the SPS.
