Mrs DeVos has put money and effort behind vouchers, which parents can spend at private schools, and charter schools—public schools operating autonomously. In Michigan, her home state, the results have been poor. In a state where test scores have declined over the past decade, 80% of charters are below the state average in reading and maths. This is partly because Michigan ignored lessons from elsewhere.
贝琪•狄维士投入资金和精力推行学卷,家长可以在私立学校和特许自主办学的公立学校使用。但在她的家乡密歇根的成绩并不理想。在一个考试成绩已经连续十年下降的州地区,已经有八成的特许学校在阅读和数学上的成绩低于州平均水平。这其中部分原因是密歇根没有吸收其他地区的经验教训。
ese is to exercise oversight. Milwaukee, the city in Wisconsin where school-choice was pioneered, began by allowing virtually anyone to open a school. This invited chancers, including a convicted rapist and a man who used taxpayers’ money to buy himself a pair of Mercedes-Benz cars. As a result, Milwaukee is now more careful about who can start a school. So is Massachusetts, which has some of the best charters in the country. Michigan, in contrast, has favoured quantity over quality: the state is home to three of the ten school districts with the highest share of charter students in America.
