Improving low-achieving schools is a critical challenge facing urban education. Recent national policy shifts have pressed states to take an expanded role in school improvement efforts. In 2009, a federal grant competition called Race to the Top (RttT) compelled states to improve their capacity to implement ambitious education reform agendas. Drawing on the theory of organizational capacity, the study sampled five RttT winning states' plans to support improving low-achieving schools. Findings indicate that states sought to build capacity to productively enact an expanded role and focus resources and expertise toward school improvement initiatives.
