Analysis / Class size
Class size vs MCPS targets
Reported class sizes run below MCPS's own targets in every category
Raw class sizes are hard to interpret because MCPS uses different targets by level, grade band, and Focus/Title I status. This page compares reported averages with MCPS's published targets.

Class-size trend
Average class size by school year, back to 2017-2018 (earlier years from the Schools at a Glance books). Years through 2022-2023 are greyed: the 2023-2024 reports redefined secondary class size (English/Other jumped ~7 students in a single year at every school — a definition change, not a real one), so the two spans are not comparable. Within the greyed span the story is real, though: elementary class sizes dropped sharply in 2020-21 and stayed low for three years — the low 2022-2023 point was the third year of a COVID-era regime, not a one-year outlier — and the comparable 2023-24 → 2024-25 years show a partial rebound that still sits below pre-pandemic levels.

Elementary lines follow a fixed cohort — schools grouped by their 2025 Title I / Focus designation — averaged across kindergarten and grades 1–5. Secondary is the average of English and other academic classes. Averages of school-level class-size averages, not individual sections.
Category summary
Each category's average compared with its published target. No category's district-wide average exceeds its MCPS target; cells shade deeper teal the further below target they sit. Elementary uses different targets for general and Focus/Title I schools; secondary uses the published base targets, and course mix makes “Other” less comparable than English.
Elementary
| Target group | Kindergarten | Grades 1–3 | Grades 4–5 |
|---|---|---|---|
| General | 18.8(-6.2) | 20.2(-6.8) | 22.8(-6.2) |
| Focus / Title I | 16.5(-2.5) | 18.0(-7.0) | 22.3(-4.7) |
Secondary
| Level | English | Other |
|---|---|---|
| Middle | 24.0(-6.0) | 23.2(-9.8) |
| High | 24.1(-5.9) | 22.9(-10.1) |
Each cell is the average class size, with its gap to the MCPS target in parentheses (the target itself is the average minus the gap). Every category is under target; deeper teal is further below, and the palest cells — kindergarten — sit closest to the target line, which is why a few kindergarten schools still land above it.
Kindergarten: low targets, wide spread
Kindergarten classes average 2–5 students below target, like every other category, yet about 8% of kindergarten schools land above target, versus 0.3% across all other categories combined. The reason is statistical rather than crowding: kindergarten has the district's lowest targets (19 and 25), sitting only about one standard deviation above the average class, and the widest school-to-school spread. With the target line that close to the middle of the distribution, the highest few schools clear it while the typical school sits well under.
School explorer
One row per school, searchable and sortable. Each cell is the average class size with its gap to that school's published target in parentheses; ▲ marks a grade or subject above target. The comparison is against MCPS's own target, not a ranking of school quality: an average just above target does not mean every class is over, and it can shift year to year with enrollment.

Limitations
- MCPS class-size guidelines are targets/formula inputs, not hard caps.
- Elementary Grades 1 to 3 is compared to a target range because School Profile data combines grades that MCPS targets separately.
- Secondary English is more comparable than the broad secondary Other category, where course mix varies by school.
- The MCPS class-size page notes an additional secondary adjustment for schools with higher FARMS rates, but the threshold is not published there, so secondary comparisons use the base guideline only.
