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.
