NLTS 2012 is the third and most recent study in the NLTS series and is still ongoing. The NLTS 2012 includes sampling data and survey data collected in 2012–2013 from approximately 12,000 youth ages 13–21 and their parents, of which about 10,000 are students with IEPs representing each of the federal disability categories. Among youth with an IEP are students who represent each of the disability categories recognized by IDEA 2004, and among youth without an IEP are students with a plan developed under Section 504 of the Rehabilitation Act.
