This book presents strategies for using systemic theory and evidence-based practice in schools to support students, the adults in their lives, and their wider communities. Beginning by introducing and explaining the Advocating Student-within-Environment (ASE) theory, each chapter then addresses a specific school-based issue, such as academic achievement, crisis, trauma, and resiliency, from a systemic and environmental lens.Practical and accessible, the chapters are filled with case examples, evidence-based interventions, and helpful tools to show how counselors can incorporate the approach into their practice.Extending beyond school and student problems, this text also explores greater system functioning, such as community outreach and state level intervention, discussing advocacy and political issues. This book is essential for school-based professionals who are looking for new ways to work with students, families, and their communities.It will also be of interest to mental health professionals who work systemically, such as marriage and family therapists and community counselors.
