Adult Level Tables

This section presents information on adults' work credentials—that is, their certification and licensure status—as of 2012. Additional data on work credentials, as well as on other forms of adult education and training, will be available in 2018, following the 2016 administration of a new NCES survey of adults. 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 and 2014.

Below are links to the major topics of this section. In addition, all NCES tables can be searched with words or phrases, using the Tables and Figures Search.
