Final answer:
Students usually need to complete all required training before working in a public capacity; this ensures competency and adheres to regulations. In terms of U.S. labor statistics, individuals working part-time, including students and senior citizens, are considered employed.
Step-by-step explanation:
The question addresses whether a student can work publicly without completing the necessary technical instruction and practical training for the service a patron is paying for. If we refer to general labor standards and practices, the answer would most commonly be No, they must complete all required training before working in a public capacity. Regulations in various fields require that individuals are properly trained to ensure competency and safety in their work. This typically encompasses an assessment of the student's ability to perform tasks within a practicum and the character traits needed to be successful in their field, as well as an understanding of how the practicum fits into their overall educational journey.
Regarding U.S. labor statistics, a person is considered 'employed' if they are working part-time, even if they are out of school. A full-time student working 12 hours a week at a college cafeteria is also considered employed. Similarly, a senior citizen who receives social security and a pension and is working as a greeter at Wal-Mart is counted as employed. Being in the labor force depends on active participation in work, regardless of age, student status, or additional sources of income.
