The tables below present information on adults' work credentials—that is, their certification and licensure status—as of 2012. These tables use data from the Census Bureau's Survey of Income and Program Participation (SIPP). Additional data on work credentials, as well as on other forms of adult education and training, will be available in 2016 or 2017, following the 2015 administration of a new NCES survey of adults. This new survey will replace previous NCES surveys on adult education that were administered from 1991 through 2005. For more information on the development of the new survey, see the GEMEnA website.
Data on adult education and training from the NCES adult education surveys conducted in 2003 and 2005 are available at the link on the left. In addition, information on adult skill levels is available from a national assessment of adult literacy (NAAL) conducted in 2003 and from an international adult skills assessment (PIAAC) conducted in 2012.
