Best Public Schools in Zip Code 22066

Zip code 22066 (Great Falls, VA) is served by two outstanding public elementary schools — Forestville Elementary and Great Falls Elementary — both part of Fairfax County Public Schools, covering grades PK-6 with no middle or high schools in the zip code.

Both schools are elite by any measure. For the 2025-2026 school year, Great Falls Elementary is the current standout, ranking #12 out of 1,111 Virginia elementary schools (99th percentile, 5 stars) after climbing from #63 two years ago. It posts remarkably balanced proficiency rates of 93.8% in math, 94.9% in reading, and 95% in 5th-grade science, and it also has the lower student-teacher ratio (14.0 vs. 15.7) and higher per-student spending ($12,650 vs. $10,971). Forestville Elementary, meanwhile, has been the more consistent historical high performer, ranking #13 and #14 in the previous two years before slipping to #41 (still 96th percentile, 5 stars). It remains the only school in the zip code offering Algebra I at the 6th-grade level, with a perfect 100% proficiency rate, and it serves more students (571 vs. 513) while spending less per pupil.

The clearest difference between the schools lies in 5th-grade science and math. Forestville's 5th-grade science proficiency dropped sharply from 92.5% to 80.95% in one year, leaving a 14-point gap behind Great Falls (95%). Forestville also posts a 5th-grade math proficiency of just 85.37% versus Great Falls' 95%, which helps explain the rank swing. Both schools benefit from a very affluent, low-risk student population — only about 6-7% of students qualify for free or reduced-price lunch, and chronic absenteeism runs around 7.6-7.8% compared to 11.9% districtwide and 14.8% statewide. In short, families in 22066 have access to two exceptionally strong elementary schools; Great Falls currently holds the edge on overall rank, science, reading, and class size, while Forestville offers a proven advanced math pathway and a larger enrollment. Note that secondary schooling will require looking outside this zip code, as no middle or high schools are located in 22066.
