The Occupational Information System (OIS) is a formal standardized system for the collection, analysis, and dissemination of occupational information that has been mandated by several major pieces of educational legislation. Designed to aid a wide audience--including direct participants in the labor market, persons whose job it is to help others prepare for the world of work, and planners and administrators--an OIS includes the following four data categories: occupational demand, occupational supply, occupational characteristics, and complementary information. A fifth component involves a procedure for interfacing and analyzing occupational supply and demand data. Because it is intended to be a user-oriented system, the OIS will be complemented with a comprehensive user education and training program. The State Occupational Information Coordinating Committee (SOICC), the body charged with coordinating the necessary resources to develop and implement an OIS, has the following four operational alternatives for OIS development: an information clearinghouse, a publication-producing OIS, a network of interrelated programs and systems, and a comprehensive computer-based system. (Concluding this report are a SOICC director's strategy for developing an OIS along with descriptions of agency programs and other data sources relevant to the OIS; occupational, industrial, and instructional classification structures; cross-code references; and OIS development aids.)
