This 2012 randomized controlled trial examined the effects of the New York School Choice Scholarships Foundation Program on the college enrollment outcomes of 2,600 first- to fifth-grade New York City public school students. The voucher program provided private school vouchers to public school students from low-income families. This is a well-implemented study, and the research meets WWC evidence standards without reservations.
In this 2012 study, researchers examined the impacts of four different types of teacher incentive strategies on student math achievement in nine K–8 public schools in Chicago Heights, Illinois. The four types of incentives experimented with the idea of “loss aversion,” the preference to avoid loss rather than acquire gains, and individual and team responsibility. This study is a well-implemented randomized controlled trial, and the research meets WWC evidence standards without reservations.
