This report presents data on adults' training and education in the United States as of 2016. The report focuses on nondegree credentials and work experience programs. Nondegree credentials include two types of work credentials--certifications and licenses--and postsecondary educational certificates. A certification is an occupational credential awarded by a certification body--such as a professional association or certifying board--based on an individual demonstrating through an examination process that he or she has acquired the designated knowledge, skills, and abilities to perform a specific job; examples include Cisco certified network associate (CCNA) certification and medical technician certification. A license is an occupational credential awarded by a government agency that constitutes legal authority to do a specific job; examples include a medical license and an electrician's license. A postsecondary educational certificate is similar to a degree; it is a credential awarded by an educational institution based on completion of all requirements for a program of study, including coursework, assessment, or other performance evaluations. In this report, only certificates awarded below the bachelor's degree level (i.e., subbaccalaureate certificates) are counted. These certificates are typically awarded in occupational fields, such as administrative support, computer graphics, culinary arts, and HVAC. Work experience programs include internships, co-ops, practicums, clerkships, externships, residencies, clinical experiences, apprenticeships, and similar programs. Characteristics of the adults who earn these credentials and complete these programs are also presented, including sex, race/ethnicity, age, level of education, labor force and employment status, earnings, job sector, and occupational field. The data for this report come from the Adult Training and Education Survey (ATES), administered as part of the 2016 National Household Education Surveys Program (NHES:2016). The ATES collects information from noninstitutionalized adults ages 16 to 65 who are not enrolled in high school.
