The Difficulty of Evaluating Teachers

Colorado case study.

“It’s tough to measure the success of the law objectively, though no one seems to be claiming it had the dramatic effect that many hoped for back in 2010. Naturally, different stakeholders have different prescriptions for how to improve it. Dallman wants to reduce the role of testing; Stein says the rubric is too cumbersome; Boasberg argues there needs to be more room for subjectivity and professional judgment.”

Meanwhile, more Colorado high school graduates need remedial classes.

“The number of Colorado high school graduates who needed to take remedial classes in college . . .  increased slightly in 2015-16 over the previous year from 35.4 percent to 36.1 percent.”
