Summary:
ZIP code 40342 has one high school, Anderson County High School, serving grades 9–12, so families have no other local high school in this list to compare it with. In 2025–2026, the school’s six-subject proficiency average was 45%, compared with 39% statewide and 43% in the Anderson County district. The clearest overall finding is that the school’s average was about 6 percentage points above the state’s.
Anderson County High School is the sole local result, not a top or bottom performer relative to other schools in the ZIP code. It exceeded its district in all six tested subjects, by 1–3 percentage points. Against the state, its strongest results were Reading, at 67% proficient versus 49% statewide, and Mathematics, at 54% versus 40%. It was also ahead in Science by 6 points and Social Studies by 2 points. The exceptions were Writing and Editing and Mechanics, each 3 points below the state. So its overall advantage does not mean it leads in every subject.
Results improved across all six subjects from 2024–2025 to 2025–2026: the school’s average rose 8 points, from 37% to 45%, while the state average remained about 39%. Reading had the biggest school gain, up 19 points, and Mathematics rose 13 points. SchoolDigger ranked the school 80th of 262 schools, in the 69th percentile with 4 stars, up from 148th of 254 and 2 stars the prior year; in 2023–2024 it ranked 85th of 290 with 4 stars. Strong academic results coexist with an attendance concern: chronic absenteeism was 26%, compared with 24% statewide and 23% in the district, even as the graduation rate was 97% versus 94% statewide. The school enrolled 1,157 students, had a 17.8 student-teacher ratio in 2024–2025, and 44% of students were free/reduced lunch eligible that year; these are useful context, not explanations for results.
