A substantial body of research shows that when families can use state-sanctioned funds to pay for private school and other academic experiences, everyone wins. Students graduate high school and attain college degrees at higher rates, schools improve academic achievement and become more diverse, parents are satisfied, and taxpayers save money. A thorough literature review by the national organization EdChoice examines 175 rigorous studies of outcomes and impacts. A total of 151 studies show at least some positive effects, 12 find any kind of negative effect, and only 18 (about 10% of the total) find no visible impact one way or the other.
