Exiting Ineffective Teachers Policy
South Carolina requires that only teachers who have met all state requirements teach in core academic areas. The state does allow certified out-of-state teachers who do not meet the state's licensure requirements to teach for one year under a temporary certificate, provided they are not teaching one of the core subject areas, defined as "English, reading or language arts, mathematics, science, foreign languages, civics, government, economics, history, geography, and the arts."
South Carolina recognized the factual accuracy of this analysis.
Research has shown that "the difference in student performance in a single academic year from having a good as opposed to a bad teacher can be more than one full year of standardized achievement." See E. Hanushek, "The Trade-Off between Child Quantity and Quality," The Journal of Political Economy 100 No. 1 (1992): 84-117. Hanushek has also found that highly effective teachers can improve future student earnings by more than $400,000, assuming a class of 20. "The Economic Value of Higher Teacher Quality."
