I have recently written about the problems in trying to use student achievement data to measure teachers’ effectiveness.
But that doesn’t mean that I think teachers’ effectiveness should not be measured.
Indeed, I think it’s essential that it is.
People focus on just one of the uses to which measurement of teachers could be put: rewarding the successful and firing the unsuccessful. But if you’re interested in improving the practice of teaching, you must have a method of measuring teachers’ effectiveness.
