Data table
| Series | 2019 | 2021 | 2022 | 2023 | 2024 | 2025 | 2026 |
|---|---|---|---|---|---|---|---|
| ELA | 63.4% | 71.3% | 60.2% | 60.7% | 64.3% | 68.1% | 73.2% |
| Math | 12.3% | ≤5% | ≤5% | ≤5% | 11.9% | 5.4% | ≤5% |
| Science | 81.8% | 57% | 34.6% | 44.1% | 47.8% | 58.4% | — |
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.
