Data table
| Series | 2019 | 2021 | 2022 | 2023 | 2024 | 2025 | 2026 |
|---|---|---|---|---|---|---|---|
| ELA | 63.1% | 56.5% | 66.8% | 74.8% | 74.5% | 67.6% | 64.6% |
| Math | 66.4% | 52.5% | 54.3% | 57.8% | 60.7% | 58.7% | 53.3% |
| Science | 67% | 76.9% | 65% | 61% | 50.3% | 51.5% | 56.8% |
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.
