Inside the Classroom: A Rigorous STEM Curriculum
What sets TJ apart academically isn’t just the difficulty of its coursework — it’s the depth and specificity. Students don’t just take generic science and math classes; they dive into highly specialized areas that most undergraduates don’t encounter until their junior or senior year of college.
The IBEST Program for 9th Graders
All incoming freshmen at TJ begin their journey with the Integrated Biology, English, and Science of Technology (IBEST) program. This interdisciplinary course sequence bridges scientific inquiry with writing and communication, establishing a strong foundation for the research-heavy years ahead. IBEST prepares students to think like scientists from day one — forming hypotheses, analyzing data, and presenting findings clearly.
Advanced Placement (AP) Course Offerings
TJ offers an extensive suite of Advanced Placement (AP) courses across every academic discipline, including AP Calculus (AB and BC), AP Physics, AP Chemistry, AP Biology, AP Computer Science, AP Literature, AP U.S. History, and many more. With 100% student participation in AP exams and pass rates well above the national average, TJ students arrive at college with a significant head start.
Unique Course Highlights
Beyond standard AP fare, TJ offers courses you simply won’t find at a typical high school: DNA Science (hands-on molecular biology and genetic engineering), Marine Biology (oceanographic study with lab and field components), Robotics & Engineering (design, build, and program functional robotic systems), Astrophysics (stellar phenomena, cosmology, and space science), Quantum Physics & Optics (modern quantum mechanical principles), Neuroscience (the brain, behavior, and neural systems), Oceanography (Earth’s ocean systems and marine environments), Research Statistics (applied statistical methods for scientific work), and Computer Systems (architecture, operating systems, and low-level programming).
This breadth of specialized coursework allows students to pursue genuine academic passions rather than following a one-size-fits-all track.
The TJHSST Research Experience: Learning Through Discovery
If one feature defines TJ above all others, it’s the school’s commitment to authentic scientific research. This isn’t science fair preparation — it’s serious inquiry conducted in professional-grade facilities alongside real mentors from industry and academia.
The Mandatory Senior Research Project
Every TJ student must complete a Senior Research Project before graduating. This capstone experience requires students to identify an original research question, conduct an independent investigation over the course of their senior year, and present findings to a panel of scientists and engineers. Many students pursue their projects in partnership with mentors from universities like George Mason, George Washington University, or institutions in the broader Washington D.C. metro area, as well as government agencies and private-sector research firms.
The senior research project is not a formality. It produces publishable-quality work, and many TJ students go on to submit findings to prestigious national competitions as a direct result. It is perhaps the single most powerful differentiator between a TJ education and nearly any other high school experience in America.
State-of-the-Art Research Labs
TJ is home to 15+ specialized research laboratories, each equipped with professional-grade instruments and overseen by faculty with real expertise in those fields.
Astronomy Lab — Equipped with telescopes, spectroscopes, and access to remote observing platforms, supporting research in celestial mechanics, stellar classification, and astrophotography.

Beyond the Classroom: TJ3Sat & TJREVERB
Perhaps no single achievement illustrates TJ’s research culture better than TJ3Sat — the first CubeSat (small satellite) ever designed, built, and launched by high school students. Developed entirely by TJ students under faculty guidance, TJ3Sat was launched into low Earth orbit aboard a NASA rocket, where it successfully transmitted data. The project demonstrated that high school students, given the right environment and support, can contribute meaningfully to the aerospace industry.
TJREVERB is another student-led engineering initiative at TJ, continuing the school’s tradition of tackling ambitious, real-world technical challenges. These projects are not outliers — they reflect a school culture where student ambition is taken seriously and given the resources to flourish.
TJ’s admissions process is competitive, selective, and — in recent years — the subject of significant legal and policy debate. Here’s what you need to know.
Who Can Apply? Eligibility Requirements
TJHSST is a regional magnet school serving a consortium of Northern Virginia jurisdictions. To be eligible to apply, students must be currently enrolled in 8th grade and attend school in one of the participating jurisdictions: Fairfax County, Arlington County, Loudoun County, Prince William County, the City of Falls Church, the City of Fairfax, the City of Manassas, or the City of Manassas Park. Students must also have a cumulative GPA of 3.5 or higher and have completed or be currently enrolled in Algebra 1 (or a higher-level math course). Students with disabilities and English language learners are encouraged to apply and considered under the holistic review process.
Step-by-Step Application Guide
The admissions process has evolved significantly in recent years, moving away from a standardized admissions test toward a holistic review model.
Step 1: Check Eligibility — Confirm the GPA and Algebra 1 requirements are met, and that the current school is in a participating jurisdiction.
Step 2: Complete the Student Portrait Sheet — The core of the TJ application. Students describe their interests, experiences, and motivations in their own words, capturing a full picture beyond grades alone.
Step 3: Write the Problem-Solving Essay — A short essay in response to a prompt that assesses critical thinking, creativity, and the ability to communicate reasoning — skills central to success at TJ.
Step 4: Submit Academic Records — Official transcripts confirming GPA and math coursework.
Step 5: Experience Factors Review — The holistic review considers socioeconomic background, English language learner status, special education history, and other contextual factors.
Step 6: Regional Seat Allocation — A portion of seats are reserved for students from each participating jurisdiction, ensuring geographic diversity.

Understanding the Admissions Statistics
Historically, TJ’s admit rate has hovered around 10–20%, making it one of the most selective public high schools in the nation. In recent years, approximately 480–550 students are offered admission from a pool of several thousand applicants.
In 2021, FCPS eliminated the previous standardized admissions test in favor of the current holistic model, in part to address demographic diversity concerns. This change was challenged in federal court, and courts have upheld FCPS’s authority to design its own admissions criteria. The debate over equity and academic selectivity continues, and families should consult current FCPS guidance for the most up-to-date policy information.
What hasn’t changed is the fundamental standard: TJ is looking for intellectually passionate, academically strong students who are genuinely excited about STEM.
