NASDSE Mission (adopted October 2015) NASDSE’s mission is to work with state education agencies to ensure that all children and youth with disabilities receive the educational supports and services they need from birth to be prepared for post-school education, career and independent living choices. NASDSE accomplishes its mission by establishing and maintaining relationships with those individuals and groups responsible for the development of policies, educational and other programs serving individuals with disabilities, and those responsible for implementation at the school, local district, state and national levels. NASDSE promotes leadership development through collaborative relationship building with these stakeholders based on its Leading by Convening initiative and strategies.
