Susan M. Dynarski was quoted in a Wall Street Journal blog about the research comparisons of student performance at charter schools versus traditional schools. Though many charter schools use a lottery system to select students, the systems aren't standardized. "The states require the lotteries, [so there is] no reason they cannot be more standardized," Susan Dynarski told the Wall Street Journal. "It's such a waste! We have little randomized trials going on all over the country, and we could learn so much from them. [It] makes a researcher’s heart break."
