Looking at grades, science is a signature strength: Biology End of Course was 75% proficient in 2025-26, far above the district's 45.63%. ELA is strong in grades 6 and 7 (60.95% and 62.18%), while 8th-grade math (36.28%) sits only slightly above the state average, making it the clearest academic soft spot. About 42.15% of students qualify for free/reduced lunch—the lowest among nearby schools—and per-student spending is $10,798, the highest in the group. However, the student-teacher ratio of 15.7 is also the highest nearby and has risen since 2022-23, a trend worth watching.
