TJ Admissions by Middle School, 2017 to 2029: What Changed After 2020

Before 2020, the middle school a TJ applicant came from lined up with very different results. In the FCPS records we have for the Classes of 2017 through 2021, Rachel Carson applicants received offers 35.5% of the time on average, while Luther Jackson and Mark Twain applicants received offers 13.9% of the time. Since the admissions process changed, those gaps have narrowed. Carson's rate has come down, Luther Jackson's and Twain's have gone up, and schools like Longfellow and Rocky Run look much as they did before.

This post walks through what changed in 2020, how seats are now tied to middle schools, and what the school-by-school numbers show for the Classes of 2025 through 2029. Every rate here is the share of a school's applicants who received an initial offer, taken from FCPS public records.

What Changed in 2020

In the fall of 2020, the Fairfax County School Board replaced the old TJ admissions process. The old process started with an admissions test, and students who scored well enough moved on to a semifinalist round. A student's middle school had no bearing on how many seats were available to students like them.

The current process drops that admissions test. Applicants who meet the eligibility requirements, including at least a 3.5 unweighted GPA in core courses, are reviewed holistically. FCPS looks at the core GPA, the Student Portrait Sheet, the Problem-Solving Essay and the experience factors listed on its application page. The biggest structural change, and the one this post is about, is that seats are now tied to middle schools.

The Class of 2025, which applied during the 2020-21 school year and received offers in spring 2021, was the first class admitted this way.

How Seats Are Allocated by Middle School

FCPS presumptively allocates each participating public middle school a number of seats equal to 1.5% of its eighth-grade class. The base is the whole eighth grade, not the students who apply. Participating schools are the public schools in Fairfax County and the cooperating school divisions. From there, offers are made in order:

1. Applicants from each participating public school are compared with other applicants from the same school first. The strongest evaluated applications from that school fill its allocated seats.
2. If a school doesn't have enough eligible applicants to fill its allocation, the unfilled seats move to the unallocated pool.
3. Public-school applicants who didn't receive an allocated seat are then considered for the unallocated seats, along with private-school and homeschooled applicants. Those seats go to the highest-evaluated applicants in that group.

Two things follow. First, 1.5% is a starting point for a school, not a ceiling. A school can end up with more offers than its allocation because its applicants can also win unallocated seats. Second, FCPS doesn't publish how the 550 seats in a class divide between allocated and unallocated seats. Any split you see quoted is someone's estimate, not an FCPS figure. Our guide to the 1.5% rule covers the mechanics in more detail.

The Numbers, School by School

FCPS records give pre-2020 averages for ten middle schools. The table sets each one beside its average since the change and its most recent released rate. The averages since the change are averaged across the classes with released data, which isn't every class for every school. FCPS doesn't release a school's rate for every class, and we don't estimate the missing ones.

For comparison, the offer rate across all applicants has been between 18.1% and 21.6% in each class since the change. For the Class of 2029, FCPS made 550 offers to 2,605 evaluated applicants, or 21.1%.

Where Rates Fell

Rachel Carson shows the largest drop. Its applicants received offers 35.5% of the time under the old process. Since the change, its rate has stayed in a fairly narrow band, from 17.1% for the Class of 2025 to 23.5% for the Class of 2027, and it was 23.0% for the Class of 2029. Carson was above the overall rate in four of those five classes, but it's no longer in a different range from everyone else.

Kilmer's Class of 2029 rate of 12.0% looks like a steep fall from its old 22.1%. The yearly numbers are less tidy than that. Kilmer came in at 12.6% for the Class of 2026, then 31.8% and 31.0% for the next two classes, then 12.0%. Averaged across those four classes, it's 21.9%, almost exactly where it was before. Looking only at the latest year would give you the wrong picture.

Where Rates Held or Rose

Longfellow is the clearest case of a school that held its position. Its old average was 32.1%, and its Class of 2029 rate was 33.6%, the highest of any middle school in the Class of 2029 records. Its average since the change, 26.6%, is lower than before but still the highest of these ten schools.

Rocky Run averaged 23.7% under the old process and came in at 24.7% for the Class of 2029. Its average since the change is a little lower, at 20.2%, because three of its five classes came in between 16.7% and 18.9%. Frost went the other way: its 19.0% for the Class of 2029 is its lowest since the change, but its 23.1% average is slightly above its old 22.4%. Lake Braddock was 15.0% before and 15.0% for the Class of 2029, with a 16.2% average in between.

The two schools at the bottom of the old list both moved up. Mark Twain went from 13.9% to 21.1% and 21.4% in the two classes with released data, right next to the overall rate of 21.6% in both of those years. Luther Jackson also started at 13.9%. Its average since the change is 24.7%, but that's pulled up by a 41.1% rate for the Class of 2028. Its other two released classes were 15.7% and 17.2%, much closer to where it was before.

The Pattern Across Schools

Side by side, the old averages for these ten schools ran from 13.9% to 35.5%. Since the change, the averages for the eight schools with released data run from 16.2% to 26.6%. Schools that used to sit well above the overall rate have come down toward it, and the two lowest have come up.

The seat allocation is one likely reason. When each school's applicants are compared with one another first, a school with many strong applicants fills its own allocated seats and then sends the rest of its applicants into the unallocated pool, where they compete with everyone else. The records can't separate that effect from the other changes made at the same time, like dropping the admissions test, so we'd treat it as part of the explanation rather than all of it.

Langston Hughes and Thoreau are in the old records, at 21.7% and 26.8%, but FCPS hasn't released a school-level rate for either one since the change. We can't say how they moved.

Why One Class Can Mislead

A school's rate in a single class depends on who applied from that school that year, so it moves around. Kilmer went from 31.0% to 12.0% in one year. Luther Jackson went from 41.1% to 17.2%. Neither change means the school suddenly got better or worse at preparing students for TJ.

When you look up your own school, the average across the classes with released data is a steadier guide than any single year. Neither number is a forecast for your child, because both describe groups of students who have already applied.

What It Means for Your Family

Your middle school decides who your child is compared with first. At a participating public school, the first comparison is with classmates applying from the same building, for that school's allocated seats. If that doesn't produce an offer, the second comparison is with the whole unallocated pool.

What decides both comparisons is the application itself. Every eligible applicant has cleared the same 3.5 GPA floor, and grades among applicants are tightly bunched, so the Student Portrait Sheet and Problem-Solving Essay carry much of the weight. That's where preparation time pays off, and it's the same work whether your school's latest rate was 12.0% or 33.6%.

We don't see anything in these records that would justify changing middle schools for TJ purposes. The gaps between schools are smaller than they used to be, and a single year swings too much to plan around. You can see the full class-by-class history for your school on our middle school pages.
