How to read these scores
What is SC READY?
SC READY is the statewide standardized test administered by South Carolina public schools.
What does "% Meets or Exceeds Expectations" mean?
It is the share of students at the school who performed at grade level or above on the test, summed across the top two of four performance levels. A higher number is better.
What does 76.6% mean for English Language Arts at Charleston Development Academy?
It means about 76.6 percent of students tested at Charleston Development Academy performed at grade level or above on the SC READY English Language Arts test in 2024-25. The statewide average for South Carolina that year was 59.7%. The other students fell into the lower performance levels.
How is the state average calculated?
It is a weighted average, not a simple average of each school's number. We multiply each public school's score by how many of its students tested, add those together for all schools in South Carolina, and divide by the total students tested that year. This way a big school with 1,500 students counts more than a small school with 50 students, which is the right way to ask "how did the typical student do this year?". District and county averages on this page use the same method, just scoped to that district or county.
Where does this data come from?
South Carolina Department of Education, South Carolina College- and Career-Ready Assessments (SC READY). School-level All Students subgroup from the SCDE Data Files. Headline metric is the cumulative "Meets + Exceeds Expectations" rate (top 2 of 4 SC READY performance levels: Does Not Meet / Approaches / Meets / Exceeds).
How often is it updated?
SC READY is administered once a year (spring). Results are released by the state in the summer or early fall. We refresh this page after each annual release.
