Nationally recognized research from the Cleveland parental school choice program has shown that parents who exercise school choice are much happier with their child's school and much more involved with their child's education. Two studies of Milwaukee's parental school choice program have found that students randomly selected to enter school choice programs outperformed similar students who applied for the program but lost a random lottery and had to return to public schools. Participants in Florida's McKay Scholarship Program for Students with Disabilities have enjoy smaller class sizes and experience significantly fewer behavioral problems and instances of bullying. In Milwaukee, an empirical study found that private schools participating in the parental school choice program had dramatically higher graduation rates than the Milwaukee public schools – 64% graduated from private schools, compared to a 36% graduation rate in public schools.
