There is no local top or bottom school to compare: with only one school listed, Limestone is both by default, not a demonstrated leader or laggard among nearby schools. Within its results, science is the strongest subject relative to the state, with a 34% school average versus 48% statewide, a 14-point gap; math is weakest, at 24% versus 39%, a 15-point gap.

Graduation is a relative bright spot at 91%, about 1 point above the state’s 90%; chronic absenteeism is higher, at 29% versus 24% statewide.
Test results declined from 2024–2025 to 2025–2026: the school’s nine-result average fell from 36% to 33%, while the state average shifted by less than one point. The average gap widened from about 12 to about 14 percentage points. SchoolDigger’s statewide standing also fell, from the 53rd percentile and 3 stars in 2023–2024 to the 37th percentile and 2 stars in 2024–2025, then the 23rd percentile and 1 star in 2025–2026.
