Chief among them has been this notion from state superintendent Tony Evers that the state’s new accountability system, known as state report cards, shouldn’t be used to determine which districts get vouchers.
Under Walker’s plan, districts with at least 4,000 students and two or more schools getting a D or an F under a new rating system would be eligible for vouchers. Evers — no fan of vouchers anyway — says the report cards were not intended for such use and need more refinement over several years.
But what was the purpose of spending more than a year working with a diverse group of education and business groups and state elected officials to create the report cards — which replaced the widely panned No Child Left Behind system — if not to use them to make consequential decisions about education?
On Thursday, Department of Public Instruction director of Education Information Services John Johnson called the report cards a “work in progress” that aren’t an appropriate tool for making a “major policy decision.”
Among their current limitations are that they are based on tests that are expected to change two years from now, they can’t show growth in high school student achievement, some schools weren’t rated, and there’s too little data to reliably identify trends in school performance.
Adam Gamoran, director of the UW-Madison-based Wisconsin Center for Education Research and a skeptic on voucher programs, agrees that the tool isn’t perfect and may well change, but “that doesn’t mean we shouldn’t use them now” to rate schools.
It’s also not as if DPI itself didn’t expect to use the report cards. Its budget request — which Walker didn’t include in his budget — included about $10.3 million over the next two years to replicate best practices from schools deemed high-performing by the report cards, as well as to help schools deemed low-performing by the report cards get better.

“Schools should not rely on only WKCE data to gauge progress of individual students or to determine effectiveness of programs or curriculum”.

A citizen, parent, voter and taxpayer might ask what the DPI has been
with state and federal taxpayer dollars since 2008?
