Do the effects of high-quality preschool last?

A:

Rob Grunewald, an economist with the Federal Reserve Bank of Minneapolis, has consistently found that not only is preschool a good thing for children in the short term, it also has sustaining “lower social costs, such as lower crime costs; and higher school achievement, educational attainment, and earnings. Average societal rates of return range from 7 percent to about 20 percent annually.” (Grunewald, 2016) The drop off in benefits is prevented, according to Grunewald, by ensuring children have access to high quality, full day preschool.
