Frederick Hess fears that focusing on the most disadvantaged students hinders the development of their more advanced peers:
Gap-closing strategies can be downright unhelpful or counterproductive when it comes to serving most students and families, and so can turn them off to education reform altogether. Longer school years and longer school days can be terrific for disadvantaged students or low achievers, but may be a recipe for backlash if imposed on families who already offer their kids many summer opportunities and extracurricular activities. Policies that seek to shift the "best" teachers to schools and classrooms serving low-achieving children represent a frontal assault on middle-class and affluent families. And responding to such concerns by belittling them is a sure-fire strategy for ensuring that school reform never amounts to more than a self-righteous crusade at odds with the interests of most middle-class families.
