It is the Gates Foundation that can take a great deal of the credit for this teacher evaluation movement across the country that has influenced the model in our state and that has also led to states basing up to 50% of the evaluation on student test scores. Much of what we read today about public education is the result of studies done by foundations and the resultant influence on policy makers. Much of the commentary is negative and much of what is driven by the new accountability movement is questionable. I like this recommendation from the Times editorial that calls for better balance between studies and policy.
Though Gates is moving away from his earlier advocacy for test scores, he is not backing away from finding answers to what ails public education. From this recent study and his comments, student perception surveys have replaced test scores in providing leverage in teacher evaluations. I don't know that teachers will like this any more than using test scores as measures of their worth in the classroom..
