Final answer:
Roe's field-by-level classification of occupations categorizes occupations based on six fields and six levels.
Step-by-step explanation:
Roe's field-by-level classification of occupations categorizes occupations based on six fields and six levels. The six fields include service, business contact, organization, technology, outdoor, and science. The six levels represent the complexity and training required for each occupation. They range from Level 1 (unskilled) to Level 6 (professional and technical). For example, a waiter would be classified as a Level 2 occupation in the service field, while a physician would be classified as a Level 6 occupation in the science field. This classification system helps individuals understand the different levels and fields of occupations and the skills and education required for each.
