>> that's a great question, there's been efforts by states before namely in florida to insert much more of teachers effectiveness into how he or she was evaluated and nothing happened. so these state efforts are a first attempt. and what colorado did cannot be underestimated or underplayed. it is rather amazing what that state pulled off across not just performance, because there are 12 states that are now looking at putting teacher evaluations, standardized test scores into teacher evaluations. so that's not unique. but what did happen in colorado that was unique was how clearly they committed to making teachers effectiveness a factor in every stage in the teacher's career. >> kate walsh, thank you. >> and now to the fastest three minutes in news. we go down to the wire with odd pest control and a pole dancing awareness campaign.
