Post-session data is collected and analyzed at all MEC Community Math Nights.  External research and evaluation teams have studied the impact of the MEC summer courses, leadership development work, work with administrators, and other project components since the inception of the model.  The success of the model has been documented in diverse settings.  Virtually all past and current participants, including parents, teachers, administrators, business leaders, university faculty, and other community members, highly value the MEC community engagement work. Ongoing research and evaluation informs MEC design, implementation and decision-making processes while guiding project review and collaborative planning.
