U.S. education officials say three states have not fulfilled their promises to bring their teacher and principal evaluation systems up to federal standards. But Washington, Oregon and Kansas will have one extra year to finish the work.
The new teacher evaluation systems were part of the requirements for waivers from the federal education law known as "No Child Left Behind." If the states meet the waiver's requirements, they won't need to have every child meet state academic standards in reading and math by January 2014.
So far, 40 states and the District of Columbia have been granted a one- or two-year reprieve from the requirements of the U.S. education law that was passed more than a decade ago.
