Data table
| Series | 2019 | 2021 | 2022 | 2023 | 2024 | 2025 | 2026 |
|---|---|---|---|---|---|---|---|
| ELA | 59.1% | 46.6% | 44.7% | 46% | 48.1% | 49.9% | 51% |
| Math | 47.6% | 20.8% | 25.3% | 21.3% | 22.4% | 21% | 19.9% |
| Science | 48.2% | 54.3% | 37.3% | 27.9% | 30.9% | 39.4% | 26.2% |
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.
