Teacher Bonuses Don't Help Test Scores Vanderbilt study says pay raises have little effect 17 comments Comments (Getty Images) (User Submitted) – The way to increase test scores is not to give bonuses to teachers, say researchers at Vanderbilt University. A three-year study found that offers of bonuses as high as $15,000 did little to change results. The report leaves open the question of what will increase test scores, but it casts doubt on the notion of merit pay, one of the solutions being pushed by the Obama administration. “I think most people agree today that the current way in which we compensate teachers is broken," says the lead researcher. "But we don’t know what the better way is yet.” The American Federation of Teachers agrees with the study and says training is one of the key factors that needs to be improved.
