Yesterday's Vergara v. California ruling struck down tenure and other job protections for California's public school teachers, but California isn't the only state working to change its laws on how teachers are hired and fired. Nationwide, many states are doing away with teacher protections.

According to a recent report from the Education Commission of the States, a non-partisan group funded by state governments, an increasing number of states are putting more weight on teacher performance and less on seniority when deciding who gets tenure, who keeps it, and who gets laid off.

Kathy Christie tracks state education policies for the Education Commission of the States and joins Take Two to discuss state trends in teacher tenure laws across the country and what impact Vergara v. California might have in other states.
