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.
