Data table

|---|---|---|---|---|---|---|---|
| ELA | 65.3% | 68.9% | 70.9% | 63.8% | 67.1% | 73.8% | 73.5% |

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

- Includes the board-adopted boundary change effective SY 2027–28: this school is projected to lose about 40 resident students then. Earlier years use current boundaries.
- This school enrolls roughly 350 more students than its own attendance area produces — it hosts a countywide or regional program (such as a magnet). Boundary studies count only resident students and so understate it; this forecast counts everyone in the building.
- Approved development near this school is expected to add roughly 80 students within five years (probability-weighted; approval does not guarantee construction).
