Testing Teachers

Cliff Mass:

There has been a lot of controversy about whether student assessments should be used to evaluate K-12 teachers. The media is full of debate about this topic (e.g., Wall Street Journal) and the Seattle Times has had many editorials pushing for the use of assessments such as MAP to evaluate teachers. And several foundations, supported by rich contributors, like the League of Education Voters and the Gates Foundation, are pushing teacher evaluation through student assessments.
I would like to argue that using student assessments to evaluate teachers not only has issues, but is putting the cart before the horse. First, we need to test teachers in a robust way to evaluate their knowledge of the subjects they are teaching and only allow teachers with strong subject knowledge to teach.
