Summary

Chaffee Junior-Senior High is a public high school serving grades 7-12 in Chaffee, Missouri, with 290 students. The school is part of the Chaffee R-II School District, which is ranked 320 out of 367 districts in the state and has a 1-star rating from SchoolDigger.

Chaffee Junior-Senior High has consistently underperformed the state average on MAP (Missouri Assessment Program) test scores, with only 11.5% of 8th graders proficient or better in Math and 4.7% proficient or better in English Language Arts, compared to state averages of 32.7% and 42.2%, respectively. The school's four-year graduation rate, while relatively high at 86.5% to 92.0%, still lags behind nearby high-performing schools like Jackson Senior High, which has a 95.5% graduation rate. Additionally, Chaffee Junior-Senior High has a high chronic absenteeism rate, ranging from 19.9% to 33.2%, significantly higher than the state average and nearby schools.

The school's performance has been declining over the years, with its statewide ranking dropping from 82 out of 404 schools in 2016-2017 to 322 out of 367 schools in 2024-2025. This suggests that the school is struggling to keep up with the academic standards and performance of other schools in the state. The high percentage of students from low socioeconomic backgrounds, with 52.76% eligible for free or reduced-price lunch, may be contributing to the school's academic challenges, as research has shown that students from low-income families often face additional barriers to academic success.
