Which form or forms of civic engagement have the most potential to involve young people in a socially-just diverse democracy? At a time when civic engagement will benefit from conceptual clarification, this paper addresses this question and some of the issues it raises. It analyzes four forms of youth civic engagement for a socially-just diverse democracy. It examines each one according to analytic categories, compares their similarities and differences, and raises questions for futurework. It draws upon research in psychology, sociology, and other academic disciplines; and on intergroup relations, multicultural education, social work, and other professional fields. The expectation is that systematic analysis of these phenomena as a subject of study will contribute to the quality of their practice, and move discussion of civic engagement to the next level.
