State spending for Indiana’s school voucher program grew to $153 million for the 2017-18 academic year to help more than 35,000 students attend private schools. The 7-year-old program, known as school choice, allows students to use state money to pay for tuition at non-public schools. A recent Indiana Department of Education report shows that this year marks a record high for the number of students using vouchers who have never attended an Indiana public school.
