CHEYENNE, Wyo. (AP) — Gov. Matt Mead has signed a bill advancing Wyoming's effort to help make its public school students better prepared for college and careers.

The measure begins the first phase of implementing an education overhaul process initiated by the 2011 Legislature. Lawmakers say the effort will require additional work by the Legislature next year.

The law establishes a system to measure progress of student academic growth and grade public schools on how well they are educating their students. School administrators would be held accountable for underperforming schools.

Mark Higdon, of the Wyoming School Boards Association, says the law won't be a burden on schools although he says much work remains to be done on education accountability.
