How Competitive Is TJHSST Admission from Rocky Run?

While the general TJHSST acceptance rate hovers around 15–17%, Rocky Run students often match or exceed this benchmark. That said, your main competition isn’t just from across Fairfax County—it’s from within your own school.

Internal Competition

  • Many students at Rocky Run are highly motivated, often enrolling in advanced math and participating in outside enrichment.

  • TJ’s 1.5% rule means only a set number of offers go to each middle school based on its 8th-grade enrollment. You’re being compared to your own classmates.

Quota Considerations

  • TJHSST uses quotas to ensure fairness across all schools.

  • Being in a high-performing middle school like Rocky Run means you’re in a strong environment—but also facing strong competition.

  • To succeed, you’ll need to differentiate yourself not only on academics but through holistic strengths.


How to Maximize Your Chances from Rocky Run

1. Academic Excellence Is the Baseline

TJ doesn’t admit students based on grades alone, but strong performance is essential.

  • Take Algebra I by 7th or 8th grade. Geometry or Algebra II by 8th is even better.

  • Aim for near-perfect grades, especially in math and science.

  • Join summer programs, math circles, or STEM competitions to deepen your learning.

2. Stand Out in the Student Portrait Sheet (SPS)

The SPS is TJ’s holistic review tool—used instead of test scores to assess fit and readiness.

  • Be authentic. Your voice and experiences should come through.

  • Show your thinking process, your curiosity, and your ability to reflect.

  • Avoid clichés—explain why you care about STEM and how you’ve pursued it in a unique way.

3. Master the Problem-Solving Essay (PSE)

This short essay is where many students lose traction.

  • Practice explaining your reasoning clearly. Don’t just solve—think aloud in writing.

  • Use logic that flows: “First, I…” → “Then I…” → “Therefore…”

  • Show creativity but stay grounded in realistic problem-solving.

4. Demonstrate Real STEM Engagement

TJ looks for students who go beyond the classroom.

  • Join Rocky Run clubs: MathCounts, Science Olympiad, Robotics, or Coding Club.

  • Compete in AMC 8, STEM fairs, or even host your own initiative or project.

  • Document personal learning—coding projects, science experiments, or writing about technology trends.

5. Make Strategic Use of the Quota System

The 1.5% rule ensures every school gets representation—but it also means:

  • Only a few top Rocky Run students will get offers.

  • You must go beyond good grades—be memorable, creative, and focused in your application.

  • Emphasize your unique story, not just your résumé.
