Gov. Pat Quinn and Republican Bruce Rauner (ROW'-nur) disagree on whether to impose a moratorium on new charter schools in Illinois.

The candidates for Illinois governor are facing off Monday in their final debate before the Nov. 4 election.

Rauner is a supporter of charter schools, where teachers usually are not unionized. He says "we need options for parents." Rauner and his wife have given millions of dollars to charter schools.

The businessman from Winnetka also supports voucher programs, which typically provide public funds to help pay private-school tuition.

Quinn says Illinois should impose a three-year moratorium on charter schools so the state can determine if they perform better than public schools.

The Chicago Democrat says: "We need to invest in public education."

He also opposes school vouchers.
