Summary:
ZIP code 47905 in Lafayette, Indiana, is served by a single public high school — Jefferson High School — which enrolls 2,042 students in grades 9–12 as part of Lafayette School Corporation. Because it is the only high school in this ZIP code, it is the sole option for local families, and there is no other area school to compare it against.
Jefferson High School graduates 87.7% of its students, just 2.0 percentage points below the state rate of 89.7% and exactly matching its district — a relative strength compared with its test scores. Chronic absenteeism, though, stands at 26.3%, above the district's 24.6% and well above the state's 16.7%, meaning roughly one in four students is chronically absent. About 57.98% of students receive free or reduced-price lunch, a sign of significant economic need in the student body. Proficiency is below state levels in every comparable subject: SAT Math at 17.17% versus 25.6% statewide, SAT Evidence-based Reading and Writing at 44.64% versus 51.9%, and ILEARN Biology at 30.66%, down from 36.4% the previous year.
In state rankings, the school has held 2 stars for three straight years while its percentile slipped from 47 in 2023–2024 to 39 and then 37 in 2025–2026. Resource inputs are substantial, at $14,112 per student and a 14.2 student-to-teacher ratio. The encouraging signs are year-over-year gains of 1.15 percentage points in SAT Math and a narrowing gap with the state in reading and writing. Families should weigh the near-state graduation rate against weaker math and biology proficiency and an absenteeism rate that lags the state.
