Virginia 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."
