Group counseling is an effective intervention when working in a school setting. In this article, the authors discuss the different kinds of groups offered in schools, types of group interventions, strategies to use in forming groups, and how to collaborate with others in the school. Because leading groups in schools is a specialized skill, the authors suggest that group leaders form collaborative relationships with others in the school, allot sufficient time for group counseling, advocate to change policies that might preclude groups in schools, and work with students and teachers to honor the time allotment dedicated to group counseling. © 2009 Wiley Periodicals, Inc.
