This First Look report provides selected key findings on adults' attainment of nondegree credentials (licenses, certifications, and postsecondary certificates), and their completion of work experience programs such as apprenticeships and internships. This version of the report corrects an error in three tables in the originally released version (September 2017). The row header for occupational field in tables 1, 2, and 5 had incorrectly described the estimates as restricted to employed adults. This version corrects that error to specify that the estimates are for adults who were ever employed. All estimates presented in the original report remain unchanged.
