More and more cities and states are using surveys to collect information about school climate from students, teachers and parents. These surveys have the potential to shed light on critical aspects of the learning environment, and they are being incorporated into a growing number of public and privately funded education initiatives. The US Department of Education's Safe and Supportive School grants, for example, support survey efforts in 11 states, which are gathering input about student engagement and safety, among other issues. The Research Alliance for New York City Schools has been working with the NYC Department of Education (DOE) to review and enhance its School Survey--the largest in the nation--since 2010. This work has resulted in several concrete improvements to the NYC School Survey, and has pointed to a variety of lessons for other cities that are engaged in similar efforts. This brief summarizes findings to date, and presents both the Research Alliance's and the DOE's reflections about the process of improving the School Survey. It outlines the Research Alliance's specific recommendations for changes to the NYC School Survey and next steps for analysis and improvement, as well as a set of broader lessons that have emerged from the work. This brief also includes a note from Lauren Sypek, the DOE's School Survey Director, reflecting on the process of collaborating to improve the School Survey as well as some of the changes that have been made to the survey as a result of this partnership.
