A common approach to describing the credentials required for occupations is to cite whether workers hold an educational degree beyond a high school diploma--that is, whether they hold a postsecondary degree. Using a postsecondary degree as a measure of occupational credentialing, 45 percent of labor force participants (adults who are working or looking for work) had this type of credential in 2016. This Data Point uses data from the Adult Training and Education Survey (ATES), administered as part of the 2016 National Household Education Surveys Program (NHES:2016). ATES:2016 collected information from a nationally representative sample of over 47,000 adults ages 16 to 65 who were not enrolled in high school. ATES focuses on nondegree credentials and training, including certifications, licenses, postsecondary certificates, and work experience programs. Data from the new ATES:2016 allow for a more expansive analysis of credentials; in addition to measuring degrees, the ATES identifies adults who have nondegree credentials--that is, subbaccalaureate educational certificates (hereafter, "certificates") and the two work credentials of certifications and licenses (e.g., Cisco Certified Network Associate [CCNA], cosmetology license, medical license). When these types of credentials are considered in addition to postsecondary degrees, 58 percent of labor force participants had a credential beyond high school completion in 2016.
