The Occupational Requirements Survey (ORS) publishes job-related information on physical demands; environmental conditions; education, training, and experience; as well as cognitive and mental requirements. The job requirements reflect those necessary for workers to perform critical tasks in support of the critical job functions, and not the capabilities of individual workers.
Credentials include training time required as a condition of hiring, which often results in certifications, licenses, or educational certificates and are part of the education, training, and experience requirements.
The published estimates reflect the percentage of workers with credential requirements and the time necessary to obtain them.
Credential requirements include:
Certifications which are issued by a certification body, industry association, or professional association and acknowledge that occupation specific skills and abilities exist. Certifications expire if not renewed.
Educational certificates which are issued by an educational institution (or a training provider) and certify that an occupation specific program of study was completed. Educational certificates typically do not expire.
Licenses which are issued by a government agency and constitute a legal authority to perform a specific occupation. Similar to a certification, a license expires if not renewed.
Apprenticeships, vocational training, non-credit courses, and credit courses that do not result in a degree are included in credential requirements. These credentials are included in overall credential requirements but are not separately published. When workers are expected to obtain credentials to perform critical job tasks, these requirements are included in estimates.
Not all credentials are included in the ORS estimates. Instances where:
credentials are desirable but are not required,
credentials are part of the hiring criteria but are not associated with any critical job tasks, and
certificates of attendance or participation for training that is not vocationally relevant are not included in credential requirement estimates.
In 2022, 45.2 percent of civilian workers were required to have a credential where 5.7 percent had a certification requirement and 19.0 percent had a license requirement.
Among published occupational groups, credential requirements ranged from 10.8 percent of office and administrative support workers to 92.4 percent of healthcare practitioners and technical workers. (See Chart A.)
Estimates reflect the length of time necessary to obtain the required credentials. In some instances, the duration of individual credentials cannot be separated from other education, training, and experience requirements. For example, lawyers have degrees included as part of the criteria for obtaining licenses so there is no separate time from the degree requirement. When this occurs, it is included as concurrent time (published as no associated time) with the other education, training, or experience requirements as appropriate. (See Chart B.)
The percentage of workers with credential requirements are published along with the associated length of time necessary to obtain the credential when the time is separate from other education, training, and experience requirements. For example, a license was required for 100.0 percent of hairdressers, hairstylists, and cosmetologists. For 36.2 percent of these workers, obtaining a license required time in addition to other education, training, and experience. No associated time was required for 63.8 percent of hairdressers, hairstylists, and cosmetologists required to obtain a license.
Percentile estimates for associated time provide a range of time required to obtain the credential. For example, at the 25th percentile, electricians had 1440 days (about 4 years) associated with license requirements. While at the 90th percentile, the associated time for the license requirement was 1825 days (5 years). (See Table 1.)
