The Council for Advancement and Support of Education (CASE) Insights on Alumni Engagement survey, CASE's first global survey, recently closed its fifth cycle of data collection. The survey is a mechanism for institutions to learn how to assess the engagement of their alumni in four areas-- communication, events, philanthropy, and volunteering. These observations include higher education alumni engagement by graduation cohort. How do the modes and levels of engagement change as alumni mature and the number of years since graduation increases? This report also examines modes of engagement by region. Each CASE region has an engagement profile specific to its culture and practices, highlighting the diversity of CASE's global membership.
