This report synthesizes findings from CEP's (Center on Education Policy's) research on how the No Child Left Behind Act's school restructuring requirements are being implemented in Michigan, California, Maryland, Ohio, and Georgia. Document reviews and interviews with state officials were conducted in the five states, and case study research was carried out in 19 districts and 42 schools. Among the report's findings are that more schools have entered restructuring and many remain in that status for multiple years; the "any other" restructuring option is the most popular option in the states studied; and the five states varied greatly in the supports they offered restructuring schools.
