Academic achievement is central to a person’s ability to participate fully in community life, including earning a living as an adult. Historically, however, some students were excluded from rigorous instruction and assessments, further compromising their ability to realize their goals. ICI’s National Center on Educational Outcomes (NCEO) identifies important outcomes of education for students with disabilities, English learners and English learners with disabilities. Since 1990, NCEO has provided national leadership regarding the inclusion of students with disabilities, English learners, and English learners with disabilities in instruction and assessments. An affiliated project, TIES Center, is the national technical assistance center on inclusive practices and policies for students with the most significant cognitive disabilities. Inclusion in assessments is an ongoing commitment to work for the valued membership, active participation, and learning of each student with their grade-level peers, using a wide array of school community structures, practices, and supports.
