DENVER (AP) -- Colorado lawmakers are trying to overhaul the state's teacher tenure system in the final 10 days of the legislative session.
One proposal has passed the Senate and is awaiting a House hearing.
Starting in 2015, teachers who have job protections now could lose them if their students don't improve for two straight years.
Principals would be judged on how their students and teachers are doing and would have to evaluate teachers yearly.
Teachers have been lobbying lawmakers against the bill. While some want to the current evaluation system changed, they worry about being judged by standardized tests and about principals who don't have enough time to give them feedback.
