Psychological Sense of School Membership (PSSM), developed in 1993, is one of the measures to ascertain the degree to which students feel a sense of school belonging. Students rate the extent to which they agree or disagree with statements, such as "People here notice when I'm good at something." In 2003, the Centers for Disease Control and Prevention held an international convention where the Wingspread Declaration on School Connections was developed as a group of tactics to increase students' sense of belonging and connection with their school.
