The second edition of this ground-breaking book continues the mission of its predecessor: to provide a "best principles" and "best practices" overview of the counseling supervision process, one that is firmly rooted in the recent explosion of empirical research in this field. Sponsored by the Association for Counselor Education and Supervision (ACES), the presentation is targeted primarily at master's-level practitioners who want "how-to" applications of the research literature (with examples) rather than a comprehensive review of the supervision literature. The book can also serve as a useful supplement for more academic texts used for doctoral-level instruction in counseling supervision. Key changes in this new edition include greater attention to multicultural and diversity issues and new chapters on group supervision and on technology. Also new are discussion questions and vignettes meant to enhance application of key concepts in each chapter, as well as more sample materials and forms for practice.
