Blackman High School reports 2,301 enrolled students to the National Center for Education Statistics (NCES) alongside 124.0 full-time-equivalent teachers, producing a 17.7:1 student-teacher ratio. That figure sits 13% above the Tennessee state mean of 15.6:1, signalling larger average class loads than peers in the same state.

The school offers 20 Advanced Placement courses, a stronger academic pipeline indicator than enrollment alone. Counselor coverage works out to roughly 575 students per counselor, above the ASCA-recommended ceiling of 250:1. Chronic absenteeism — missing 10% or more of school days — stands at 15.7% according to the 2021-22 Civil Rights Data Collection.
On the finance side, the surrounding Rutherford County spends $11,822 per pupil district-wide, below the Tennessee average of $12,324 and below the national average of $19,490.
