Book excerpt: A School Counselor's Guide to Small Groups: Coordination, Leadership, and Assessment provides practicing school counselors, school counseling supervisors, school counselor educators, and counselors-in-training with the knowledge and tools they need to effectively implement and lead small groups within school contexts. The book features two distinct sections. The first section includes 10 mini-chapters designed to help readers consider how to use their group leadership skills to support group implementation. The second section provides readers with more than 50 small-group session plans divided into four key categories: anxiety, social skills, decision-making, and grief. The session plans include instructions for implementation, a list of materials needed, discussion ideas, recommended grade levels, American School Counselor Association (ASCA) Mindsets and Behaviors, and learning objectives. The second edition features new chapters and activities, coverage of new group leader skills, and sidebar activities to stimulate reflective practice, including case studies, supervision questions, advice from the authors, and more. The text has been updated to reflect the fourth edition of the ASCA National Model: A Framework for School Counseling Programs. A School Counselor's Guide to Small Groups is co-sponsored by The Association for Specialists in Group Work. It is a vital and highly applicable resource for practicing counselors and counselors-in-training.
