Together they enroll 654 students; Hedding has 376 and the high school 278. The clearest finding is that Hedding’s math result is well above its state benchmark.
Hedding stands out in 2025–2026 IAR math: 57% of students were proficient, 17 points above the state’s 40%; its ELA result was 3 points below the state.

Its lowest listed comparison was grade 9 PreACT ELA, 26 points below the state. Because the schools serve different grades and their test results are not directly comparable, these benchmarks should not be used to rank the schools against each other.
