Data table
| Series | 2019 | 2021 | 2022 | 2023 | 2024 | 2025 | 2026 |
|---|---|---|---|---|---|---|---|
| ELA | 81.2% | 69.7% | 80.8% | 75.1% | 80% | 81.8% | 83.3% |
| Math | 74.3% | 36.7% | 51.1% | 48.6% | 54.3% | 54.6% | 59.9% |
| Science | 75.4% | 71.4% | 69% | 52.7% | 55.8% | 60.9% | 65.4% |
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.
