NASP is a constituent member of the National Council for Accreditation of Teacher Education (NCATE) and although NCATE accredits units (such as colleges of education), not programs, it does provide "national recognition" status to NASP-approved programs located in units accredited by NCATE.
NASP is affiliated with NCATE, which accredits educational units rather than specific teacher education programs.  However, NASP-approved programs located within NCATE-accredited units receive national recognition.
