The study examined the effectiveness of Philadelphia's Renaissance Schools Initiative after one year of implementation. The Renaissance Schools Initiative, which began in the 2010-11 school year, aimed at improving low-performing schools by providing new management, additional resources, and new educational strategies. The study reported that students in grade K-8 Renaissance Schools had higher math achievement, reading achievement, and attendance rates than students in comparison schools. This study does not meet the What Works Clearinghouse (WWC) evidence standards because the Renaissance schools and comparison schools did not have similar achievement levels in the year before the Renaissance Schools Initiative began. Therefore, any changes in student achievement or attendance cannot be attributed solely to the implementation of the Renaissance Schools Initiative.
