How do you provide more time and financial incentives for professional development with limited resources?
It has been estimated that significant improvements in education over a 20-year period could lead to as much as a 4 percent addition to the gross domestic product, or over $400 billion in today's terms (Hanushek, 2003; National Center for Education Statistics [NCES], 2002). In contrast, "high school dropouts are far more likely to be tax consumers than taxpayers, use welfare and public health services, and commit crimes. Researchers estimate that each high school dropout costs society about $209,000 over the course of his or her lifetime" (Wise, 2008, p. 9; see also Levin, Belfield, Muennig, & Rouse, 2007). Multiply this amount by the 1.2 million U.S. students who drop out of high school each year (Editorial Projects in Education, 2007), and you see that the lack of a good education can be costly.
