Distinguished economist Helen Ladd and her husband, journalist Edward Fiske, studied the accountability system for charter schools in Massachusetts. They specifically addressed equity issues of access, fairness, and availability of a high-quality education, not test scores. They found considerable variation among charter schools, as one would expect. They also found that some charter schools had unusually high attrition rates and unusually high suspension rates. These should concern policy makers, whose goal is to offer better opportunities for disadvantaged students. Their aim in writing the paper is to alert policymakers to the value of an equity-oriented accountability system that goes beyond test scores.
