Data table

|---|---|---|---|---|---|---|---|
| ELA | 47.6% | 50.6% | 56.7% | 48.3% | 51.4% | 55.6% | 59.5% |

Testing paused in 2020. A dashed line in a shaded band means the exact value is suppressed for privacy — it is ≤5%. Science scoring changed twice (2019 pre-MCAP scale; 2021 three bands, two pooled administrations; four bands from 2022), so science points before 2022 aren't comparable to later ones. Science swung sharply statewide between 2023 and 2026 (down, then back up, one grade at a time); those moves likely reflect the state assessment, not school-level change. High-school science isn’t published for 2026 yet. 2019 math reflects the larger PARCC-era Algebra 1 testing population and isn't comparable to later years.
Class size
Average class size by grade band over recent years, with the latest year measured against MCPS's published guideline.

- Includes the board-adopted boundary change effective SY 2027–28. Because this school hosts a large countywide program, its figures follow the board's adopted projection rather than a boundary ratio.
- This school enrolls roughly 575 more students than its own attendance area produces — it hosts a countywide or regional program (such as a magnet). Boundary studies count only resident students and so understate it; this forecast counts everyone in the building.
