This engaging and practical book addresses the multitude of ways in which school-employed psychological service providers such as school counselors, school psychologists, and school social workers, can support the learning, behavioral, and mental health needs of students in school settings. Psychology in the Schools offers vignette examples to apply content to real-world context and provides a variety of resources including worksheets and templates for practitioners to use in practice. Chapter content covers foundations in psychological services in schools (e.g., the hidden curriculum of school systems, professional standards of practice, consultation and collaboration, and assessment), an overview of social, emotional, behavioral, and academic supports across tiers of service delivery, and skills for practitioners to thrive (e.g., burnout prevention). This text is ideal for an upper-level undergraduate course or an introductory graduate-level course. Early career practitioners and supervisors alike can also benefit from the tools and resources that this book provides.
