What stands out at Midlands Stem Institute
Midlands Stem Institute is a high-poverty, mid-sized charter combined-grade school in Winnsboro, South Carolina, enrolling 306 students.
Class loads run heavy: 18:1 is larger than about 91% of South Carolina schools and 26% above the 14.3:1 state mean, so each teacher carries more students than is typical.
Its free-meal eligibility rate of 88.5% lands close to the South Carolina typical range, neither a high- nor low-need campus by this measure.
Enrollment of 306 puts it in the smaller third of South Carolina schools by headcount.
Its Resource Investment Index trails 98% of the 1,214 South Carolina schools with a score on record, one of the lower results on this measure.
Among 260 similarly sized, similarly resourced-need South Carolina schools statewide, it ranks #256, in the lower tier once campus size and economic need are matched.
Its student body is led by White (56%) and African American (39%) (diversity index 53/100).
Counselor coverage runs a bit thin, about 306 students per counselor, somewhat past the ASCA-recommended 250:1 benchmark.
Chronic absenteeism is elevated: 39.2% of students missed 10% or more of school days (2021-22 Civil Rights Data Collection).
The surrounding Charter Institute at Erskine spends $6,927 per pupil, 52% below the South Carolina average, a leaner-resourced district than most.
