Voucher supporters say private schools continue to outperform most public schools, while opponents say they're harming education in Indiana. But both sides agreed they could use more data on voucher recipients.
Republicans first signed off on the voucher law in 2011 and it was recently upheld by the Indiana Supreme Court, which found it did not amount to the state subsidizing certain religions. Lawmakers approved a modest expansion of the voucher program earlier this year and likely will consider further expansion when they return for their 2014 session.
The study of the vouchers was added to this year's program expansion amid concerns a more extensive plan could become a budget-buster for Indiana.
