Data table
| Series | 2019 | 2021 | 2022 | 2023 | 2024 | 2025 | 2026 |
|---|---|---|---|---|---|---|---|
| ELA | 46.2% | 63.1% | 56.6% | 51% | 60.4% | 61.6% | 63% |
| Math | ≤5% | 7.7% | ≤5% | ≤5% | ≤5% | ≤5% | ≤5% |
| Science | 31.8% | 53.2% | 38.6% | 35.6% | 35.7% | 44.9% | — |
Testing paused in 2020. A dashed line in a shaded band means the exact value is suppressed for privacy — it is ≤5%. 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. High-school science isn’t published for 2026 yet. 2019 math reflects the larger PARCC-era Algebra 1 testing population and isn't comparable to later years.
Class size
Average class size by grade band over recent years, with the latest year measured against MCPS's published guideline.
