Walker signed the bill privately Tuesday, along with another proposal designed to set tougher standards for new private schools that want to accept taxpayer-funded voucher students.
The report card bill requires private schools accepting voucher students to submit a variety of data to the state that they don't currently provide. That includes a host of demographic data, enrollment numbers and graduation rates.
The information, along with performance on state tests, will eventually be included on school report cards just like those released now for public schools.
A more expansive measure that included sanctions for failing schools failed to find enough support to pass the Legislature.
