Addressing one of education's most divisive issues, President Barack Obama on Saturday called for capping standardized testing at 2 percent of classroom time and said the government shares responsibility for turning tests into the be-all and end-all of American schools.

Students frustrated over a new standardized test are walking out of schools around New Mexico in protest. 

A bill in the Nevada Legislature would allow schools to hold off on standardized tests until students have a certain number of instructional days under their belt, rather than taking a one-size-fits-all approach with the test date.
