TRANSPARENCY TUESDAY | When North Carolina releases annual school accountability results, one of the most visible measures is each school’s School Performance Grade. It provides an overall assessment of performance outcomes from the previous school year by combining two measures: student achievement and academic growth.
ACHIEVEMENT represents 80% of the School Performance Score, and GROWTH represents the remaining 20%.
The resulting School Performance Score is converted to a letter grade:
A: 85–100 | B: 70–84 | C: 55–69 | D: 40–54 | F: Below 40
Because achievement accounts for four-fifths of the calculation, the overall grade is influenced much more heavily by how students performed than by whether they met or exceeded expected academic growth. The School Performance Grade provides a useful summary of performance, but it does not tell the whole story.
