How the 1.5% Rule Works at Sandburg
Every participating public middle school has TJ seats set aside for it, equal to 1.5% of its eighth-grade class. Sandburg had 694 eighth graders in the 2024-25 school year, which works out to about 10 seats.
Sandburg applicants compete with each other for those seats first. Anyone who doesn't get one moves into a second round with applicants from every other school. The seat count is an estimate. FCPS uses the current eighth grade, doesn't publish how it rounds, and moves any seats a school can't fill into the open pool.
In other words, your school decides who your child is compared with first. It doesn't decide the outcome. More on how the 1.5% rule works.
What Separates Applicants
Everyone in the pool has at least a 3.5 GPA, and the spread at the top is small. For the Class of 2029, students who got offers averaged a 3.96. Students who didn't averaged a 3.88. More on what the GPA data shows.
With grades that close, a lot rides on what your child writes on test day: the Student Portrait Sheet and the Problem-Solving Essay. Students get noticeably better at both with practice and good feedback, and that's the part of this you can actually work on.

Questions Parents Ask
What percentage of Sandburg Middle School applicants get into TJ?
For the Class of 2029, 16.7% of Sandburg applicants got offers, compared with 21.1% of all applicants. Sandburg has landed between 16.7% and 28.2% in each of the five classes with data since the 2020 admissions change.
How many TJ seats does Sandburg Middle School get?
About 10. FCPS sets aside seats for each participating public middle school equal to 1.5% of its eighth-grade class, and Sandburg had 694 eighth graders in 2024-25. It's an estimate, because FCPS uses the current eighth grade and doesn't publish how it rounds.
Does going to Sandburg Middle School make it easier or harder to get into TJ?
Not in a way you can count on. Sandburg applicants compete with each other first for the school's share of seats, and anyone who misses out gets a second look alongside applicants from every other school. The offer comes down to your child's own application.
What actually decides a TJ offer?
FCPS looks at core GPA, the Student Portrait Sheet, the Problem-Solving Essay, and experience factors. Every eligible applicant has at least a 3.5 GPA, so grades don't separate students much. For the Class of 2029, students who got offers averaged a 3.96 and students who didn't averaged a 3.88.
Where These Numbers Come From
Offer rates come from Fairfax County Public Schools' responses to Virginia public records requests, including the Class of 2029 admissions summary and request VFOIA-11221. They are rounded to a tenth of a percent, and when FCPS withholds a number to protect student privacy, we leave it blank instead of estimating it. Eighth-grade enrollment comes from the Virginia Department of Education's fall membership count for the 2024-25 school year. Seat estimates are 1.5% of that number, rounded. FCPS describes the process itself on its freshman application page, which is the final word if anything here differs.
