SchoolDigger rankings have improved at several schools, but the trend is not universal. From 2023–24 to 2025–26, Chinle Junior High School rose from the 16th to the 46th percentile, while Chinle Elementary School and Tsaile each gained 9 percentile points. Many Farms slipped from the 80th to the 76th percentile. Student-teacher ratios do not show a simple connection with results: Many Farms has a 10.8:1 ratio and leads ELA, while Chinle Elementary has a 17.4:1 ratio and results above the state in both subjects. Chinle High’s reported graduation rate is about the same as the state’s, at 80% versus 80%, but its dropout rate is higher: 8% versus 5%.
