Pearson Foundation Senior Fellow John Wilson writes in his John Wilson Unleashed blog in Education Week: How much longer are we going to continue down the path of absurdity seeking the promised land of teacher evaluations? Spending millions of dollars on complicated and convoluted systems that only demoralize teachers will eventually result in backlash from taxpayers and voters. Evaluating teachers on student test scores will inevitably prove once again that low income students do not test as well as affluent students and that effective teachers who want good evaluations will move to schools with higher income students. Coupling test scores of students to the evaluations of teachers who never taught those children will never hold up in court. The irony in all this is that there is an effective system for teacher evaluations, one that has been around since the 1980's. Peer Assistance and Review (PAR) programs have been the exemplar for strong teacher evaluation systems. Teachers trained to evaluate their peers are able to distinguish the inexperienced from the ineffective---a significant difference from other evaluation systems---and can help teachers improve their practice.
