Education savings accounts are the fastest growing form of school choice. Five states have ESA programs — mostly for special needs students, but more than 95 percent of students in Nevada qualify for its program. Legislation has been introduced in 18 other states so far this year that would establish more ESAs.

With ESAs, the government puts funds into an account that parents can spend toward a variety of educational needs, often including private school tuition, tutoring, educational therapy and textbooks. It’s similar to, but more flexible than, school vouchers.
