This article identifies characteristics of school districts that have been exceptionally successful in closing gaps in achievement among diverse groups of students, including students in challenging circumstances. Evidence for the paper was provided by 31 studies. These were studies, published in the past ten years, which reported original evidence about the association between one or more district characteristics and some valued set of outcomes, or described one or more practices within a district previously found to be high performing. Ten district characteristics are described and several implications for future policy, research, and practice are outlined. (Contains 1 table and 2 notes.)
