The problems with just this 25 % policy, however, and as he writes, include the following: the «policy reflects the view that teachers are inadequately motivated to do their jobs;» this implies, without any evidence that only an arbitrarily set «25 % of a district's teachers deserve a raise;» this facilitates a «culture of competition [that] kills the collaboration that is integral to effective education;» «[t] he
idea that a single teacher's influence can be isolated [using VAMs] is absurd;» and just in general that this policy «reflects a
myopic approach to reform.»
