Summary:
ZIP code 46041 covers Frankfort, Indiana, and includes two public high schools with different grade spans: Frankfort High School (grades 9–12, 922 students, part of Community Schools of Frankfort) and Clinton Prairie Junior-Senior High School (grades 7–12, 497 students, part of Clinton Prairie School Corporation). Together the listed enrollment is about 1,419 students, though Clinton Prairie's count includes grades 7 and 8. Because the schools serve different grades, the fairest comparisons are SAT 11th-grade and Biology End-of-Course scores, graduation rate, chronic absenteeism, free/reduced lunch, per-student spending, student-teacher ratio, and school rankings.
Clinton Prairie is the stronger performer on most of those shared measures. Its 2025–2026 school rank is 140 of 415 (66th percentile, 3 stars) versus Frankfort's 319 of 415 (23rd percentile, 1 star), and its district rank is 132 of 374 (3 stars) versus 248 of 374 (2 stars). Clinton Prairie also posts a higher graduation rate (94.4% vs. 92.1%; state 89.7%), lower chronic absenteeism (12.8% vs. 21.6%; state 16.7%), lower free/reduced lunch (44.87% vs. 53.8%), a lower student-teacher ratio (12.2 vs. 14.4), and higher per-student spending ($13,936 vs. $10,295). It leads on shared exams as well — for example, 2025–2026 SAT EBRW of 46.99% vs. 30.7% and Biology EOC of 54.62% vs. 34.3%. Clinton Prairie's own rankings have slipped, from 78 of 432 (82nd percentile, 4 stars) in 2023–2024 to 140 of 415 in 2025–2026, and its scores also declined year over year.
Frankfort's bright spots are its graduation rate, which is above the state average, and a modest ranking improvement from 353 of 432 (18th percentile) in 2023–2024 to 319 of 415 (23rd percentile) in 2025–2026, though it stays in the bottom quartile with a 1-star rating. Its chronic absenteeism of 21.6% is well above both the state (16.7%) and its own district (10.8%), making the high school an outlier locally. Frankfort's SAT and Biology proficiency also remain well below Clinton Prairie and, for SAT, below the state. The resource and demographic gaps — more free/reduced lunch participation and lower per-student spending at Frankfort — line up with the outcome gaps, but the data does not show that one causes the other.
