Ranking the Palmetto State’s Public & Private School Systems Using the Latest Academic Data
For families choosing where to live, schools are often at the top of the list. While no single metric tells the whole story, standardized test scores, student-to-teacher ratios, graduation rates, and college readiness provide a strong picture of educational quality.
Using the latest available 2025 South Carolina Department of Education SC READY and SC PASS assessment data, district report cards, graduation outcomes, and teacher-to-student ratios, we’ve ranked South Carolina’s strongest educational counties.

Methodology
This ranking is based on the latest available 2025 South Carolina Department of Education data, including SC READY and SC PASS assessment results, district report cards, graduation rates, teacher-to-student ratios, and college readiness indicators. Because South Carolina reports standardized testing by school district rather than county, county rankings were developed by evaluating the collective performance of the districts within each county. Private school rankings are based on institutional reputation, accreditation, college placement, academic offerings, and educational outcomes, as no statewide accountability testing system exists for South Carolina’s private schools
