National Longitudinal Study of the No Child Left Behind Act of 2001

The National Longitudinal Study of the No Child Left Behind Act of 2001 (NCLB) is a four-year longitudinal evaluation of the district and school level implementation of the NCLB, the most recent reauthorization of the Elementary and Secondary Education Act (ESEA). Together with our partners, AIR is exploring the implementation of four key components of NCLB: accountability, teacher quality, choice, and resource allocation. A report of these findings was delivered to Congress in 2007.
