Charlotte-Mecklenburg Schools (CMS) closed three middle schools and transitioned eight elementary schools to PK-8 schools in 2011. The Office of Program Evaluation (OPE) at the University of South Carolina collaborated with CMS on a three-year evaluation of the transition. The evaluation focused on the perceptions and impacts of the PK-8 structure on student attendance, achievement, and behavior. Over the course of the three-year study, OPE staff collected information from approximately 700 teachers, 600 parents, 145 students, and 30 administrators through surveys, focus groups, and interviews (numbers may represent single participants more than once).
