The document provides occupational information intended for use in elementary schools and possibly junior high schools. It lists occupations typically identified as being part of the 15 U.S.O.E. occupational clusters. Occupations listed are those that are most common to the cluster, and, generally, those common to Iowa communities. Four levels of occupations form the structural basis of the document: (1) self--those occupations directly affecting the student, (2) family or self--those occupations directly affecting the student's family through a service or product, (3) family or community--those occupations affecting the student indirectly, and (4) unknowns--those occupations unfamiliar to the student or dealing with more abstract types of work and products.
