School psychologists are a critical part of the school team that ensures quality, genuinely accessible education for all students. National Association of School Psychologists' (NASP's) "Ready to Learn, Empowered to Teach: Guiding Principles for Effective Schools and Successful Students" (2015) foundational policy document recommends that educational policies and practices be led by a series of guiding principles. Specifically, the six "Ready to Learn, Empowered to Teach" guiding principles call for: (1) high expectations within a rigorous, comprehensive for all students; (2) safe and supportive learning environments that are conducive to learning; (3) access to comprehensive school-based mental and behavioral health services and adequate staffing levels of school psychologists and other professionals; (4) family and community engagement to support student success; (5) systems to recruit and retain properly trained and prepared professionals; and (6) accountability systems that reflect a comprehensive picture of school and student success. This research summary provides examples of how school psychologists support these principles, and how their services link to research and policies regarding improved outcomes for students.
