Data table
| Series | 2019 | 2021 | 2022 | 2023 | 2024 | 2025 | 2026 |
|---|---|---|---|---|---|---|---|
| ELA | 90.6% | 61.7% | 87.3% | 87.4% | 88.4% | 91.1% | 86.5% |
| Math | 89.4% | 56% | 74% | 78.7% | 81.1% | 84.6% | 81.4% |
| Science | 81.3% | 79.2% | 76% | 72.9% | 59% | 73.2% | 72.2% |
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.
