The Friedman Index measures how much educational choice families really have in each state, and scores each state from 0 to 100. To achieve a score of 100, a given state must meet each of the following three criteria: “All Students,” meaning 100% of the students in the state are eligible and funding is available for all, “All Options,” meaning students are able to participate in an education savings-style program (ESA) and families have the opportunity to use the taxpayer funds in their child’s account for tuition as well as educational goods and services outside of schools, and “All Dollars,” meaning choice students receive the same amount of funding as public school students (sans federal funding), on average.
