Context: The school psychology program faculty are redesigning the course sequence required of M.A/Ed.S. in school psychology students and Ph.D. in education students with a specialization in school psychology. This redesign is occurring to provide students with high-quality training in contemporary best practices in assessment, prevention and intervention, consistent with (a) the National Association of School Psychologists’ (NASP’s) 2020 Professional Standards and (b) Delaware’s (DE’s) regulation requiring all schools to provide tailored, student-centered services within multi-tiered systems of support (MTSS). As a part of this curriculum redesign, faculty are proposing to revise or deactivate several courses and introduce select new courses. Specific Course Request: Since 2021, DE has required all public schools to implement MTSS for students’ academic, behavioral, and social-emotional skills (24 DE Reg. 663; 26 DE Reg. 837). This requirement is consistent with a broad and rigorous evidence base demonstrating the efficiency and effectiveness of research-based instruction, assessment, and intervention within a tiered service delivery framework. Many other states have formal requirements or recommendations for schools to implement MTSS, and MTSS implementation has been referenced in federal legislation, such as the Every Student Succeeds Act (2015), and in guidance documents, including numerous Dear Colleague Letters. Moreover, the NASP 2020 Professional Standards task school psychology graduate programs with providing explicit instruction, training, and supervision in MTSS, including the delivery of universal, targeted, and intensive practices as well as the coordination of systems change efforts to adopt, evaluate, and sustain MTSS. Presently, however, the school psychology program course sequence includes instruction and scaffolded fieldwork in MTSS only incidentally (e.g., during one class meeting in different courses). In addition, the current course sequence places undue emphasis on traditional models of individual assessment and intervention, failing to intentionally frame the role of school psychologists and other personnel as systems change agents within MTSS. We propose introducing a new course specifically on MTSS. We expect this course will best equip students with the conceptual and ecological foundations necessary to deliver and evaluate their assessment, prevention, and intervention practices in schools.
