Summary

Cosby Elementary School is a K-8 school serving 429 students in the rural mountain community of Cosby, Tennessee, within the Cocke County Schools district. The school earns a 3-star rating for 2025-2026, ranking in the 64th percentile of Tennessee elementary schools, a slight dip from its 4-star, 75th-percentile showing the previous year.

Math is the school's standout subject, with 53.1% of students proficient compared to 44.9% for the district and 43.0% statewide. Middle-grade results are especially strong: 6th graders post 62.2% proficiency and 8th graders 61.5%, both roughly 20 points above state averages. Science (51.0%) and social studies (53.7%) also outperform district and state benchmarks. The school is notably effective with economically disadvantaged students, whose performance ranked in the 88th percentile statewide in 2024-2025. English Language Arts, however, remains a significant concern at 34.5% proficiency, well below the state's 40.6%. Most telling is the steep drop from 3rd grade (55.6%) to 4th grade (28.3%), with weak scores persisting through 8th grade.

Cosby compares favorably to several nearby schools, outperforming Northwest Elementary School and Edgemont Elementary School in nearly every subject. Yet Smoky Mountain Elementary School, just 3.5 miles away, posts stronger results across all subjects, and Grassy Fork Elementary School edges Cosby out in math, science, and social studies. The school also operates efficiently, spending $12,764 per student in 2024-2025, far less than Jones Cove Elementary School ($28,788) or Del Rio Elementary School ($19,823). Chronic absenteeism is 19.1%, better than the district average of 26.2% but slightly above the state's 18.3%. If Cosby can address its post-3rd-grade reading slump, it has the potential to climb firmly into the top quartile of Tennessee elementary schools.
