National Center on Assessment and Accountability for Special Education
The purpose of the NCAASE (The Center) is to develop and test various approaches for measuring the achievement growth of students with and without disabilities.
The Center’s focused program of research on reading and mathematics achievement growth is based on existing sets of longitudinal achievement data for students with and without disabilities from North Carolina, Arizona, Oregon, and Pennsylvania.
To help examine the accountability purposes for which states are using their assessment data, NCAASE partners
with measurement and statistics experts, assessment and special education leaders in academia and in state departments of education, lead psychometricians, and a National Advisory Panel.
