Drawing on in-depth research at an urban elementary school, Posey-Maddox examines parents' efforts to support the school through their outreach, marketing, and volunteerism. She shows that when middle-class parents engage in urban school communities, they can bring a host of positive benefits, including new educational opportunities and greater diversity. But their involvement can also unintentionally marginalize less-affluent parents and diminish low-income students' access to the improving schools. In response, Posey-Maddox argues that school reform efforts, which usually equate improvement with rising test scores and increased enrollment, need to have more equity-focused policies in place to ensure that low-income families also benefit from--and participate in--school change.
