ESSA regulations require states to post on their report cards information about teachers with emergency or provisional credentials. South Carolina does not award emergency or provisional credentials, thus that metric is not listed.

Note: The method for calculating prime instructional time was adjusted for 2025 school report cards. Comparing 2025 prime instructional time to prior years is not appropriate.
