This chapter describes the contributions of school psychologists in the education of students with disabilities. School psychologists play a pivotal role in addressing students’ needs, particularly through their expertise in assessment, intervention, and collaboration within educational systems. Central to their work is the implementation of the Individuals with Disabilities Education Act (IDEA), which mandates that all students with disabilities receive comprehensive evaluations to determine eligibility for special education services. This legislative framework has shaped the field, positioning school psychologists as experts in assessing, identifying, and addressing the diverse needs of students with disabilities. Beyond evaluation, school psychologists provide a wide array of services that positively impact both individual students and the broader school environment. The National Association of School Psychologists (NASP) Practice Model guides their professional practices. School psychologists use data-based decision-making and evidence-based interventions to help ensure that students with disabilities receive the most effective support possible. Moreover, by fostering environments that promote both academic success and mental well-being, school psychologists are instrumental in creating educational experiences that are inclusive and culturally responsive. While school psychologists have the potential to improve educational experiences for students with disabilities, high student-to-practitioner ratios often limit the scope of their services. This chapter underscores the critical need for a broadened understanding and utilization of school psychologists to enhance outcomes for students with disabilities across educational settings.
