Assessment is a process used to collect information about student learning and development to improve educational programs and demonstrate their effectiveness. It involves screening, diagnosing, determining program placement and instructional evaluation. When assessing students with special needs, different types of assessments and accommodations must be made to account for their unique needs and abilities. An Individualized Education Program (IEP) is created for each student with special disabilities and outlines accommodations, goals, services and placement designed to meet their individual needs.
