The chairman of the Indiana Senate Education Committee says any proposals to expand the state's private school voucher system will have to be first approved by the Indiana House.

Republican Sen. Dennis Kruse of Auburn says his committee won't vote as planned Wednesday on a bill that would make it easier for siblings of those already in the program to also receive vouchers.

The proposal has faced some opposition because it would sidestep a requirement included in the 2011 law that all students spend at least a year in in public schools before becoming eligible for the subsidies toward paying private school tuition.

Kruse says he wants to see whether the House will approve a broader bill that would completely end the one-year waiting period.
