This issue of "Focal Point" explores how the increasing emphasis on using evidence-based practices and a "system of care" approach is driving changes in jobs and roles related to children's mental health. Articles in the issue describe how agencies and providers of services and supports have responded to these changes by creating new types of positions or by redefining existing roles. The articles also focus on training and other workforce development activities that are required to support these kinds of changes in the workforce.

Walker); (2) Direct Support Services in Children's Mental Healthcare (Tim Penrod); (3) Direct Support: How It Works (Interview); (4) Implementing "Incredible Years": Reflections on Changes in the Clinician's Role in an Evidence-Based Practice (Cate Drinan); (5) Implementing "Incredible Years": Implications for Supervisors and Administrators Working with an Evidence-Based Practice (Kathryn Falkenstern); (6) Implementing "Incredible Years": An Evaluation Perspective on an Evidence-Based Practice (Michele Limpens and Linda Magnuson); (7) Family Partners in Systems of Care and Wraparound (Trina Osher and Marlene Penn); (8) Changes at The Bridge: Promoting Family Voice in Residential Treatment Programs (Margaret Crowley and Nancy Bishop); (9) Early Childhood Mental Health Consultation: A Developing Profession (Mary Dallas Allen, Eileen M.
