Are students receiving the accommodations that enable them to meaningfully access assessments, and show what they know and can do? Through a variety of grants and partnerships, the National Center for Educational Outcomes (NCEO) seeks to make instruction and testing more accessible to students with barriers to learning. It conducts knowledge development activities and provides technical assistance on accessibility and accommodations. The Center is responsible for organizing and implementing an assessment task force for the National Deaf Center on Postsecondary Outcomes, for example, which aims to increase the number of Deaf individuals who are admitted to and thrive in postsecondary training, without remedial coursework. An NCEO affiliate known as the TIES Center focuses on the inclusion of students with the most significant cognitive disabilities in general education classes and addresses the development of communicative competence and other accessibility issues for K-8 students in inclusive settings.
