Data table
| Series | 2019 | 2021 | 2022 | 2023 | 2024 | 2025 | 2026 |
|---|---|---|---|---|---|---|---|
| ELA | 41.6% | 20% | 36.9% | 39.9% | 36.2% | 36% | 34% |
| Math | 38.3% | 15.4% | 21.6% | 29.4% | 21% | 24.4% | 24.7% |
| Science | 25.9% | 24.3% | 19.1% | 16.3% | 16.2% | 18.6% | 20% |
Testing paused in 2020. 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.
Class size
Average class size by grade band over recent years, with the latest year measured against MCPS's published guideline.
