MILWAUKEE (AP) -- Supporters of a Milwaukee school-voucher program say they're not deterred by test results showing that kids in those programs perform worse than students in public schools do.

The test results were released Tuesday by the Wisconsin Department of Public Instruction. They show that voucher students are nowhere near their public school counterparts.

Gov. Scott Walker says the overall voucher program is "exceptional." He says the priority should be to give more money to the top-performing schools.

State Rep. Robin Vos says the test scores don't tell the whole story. The Rochester Republican says some of the students came from poor schools and are still catching up, and that graduation rates are a better measure.

The Wisconsin Association of School Boards says the state should stop investing in a program that yields "questionable results."
