For use by educational planners desiring to match occupational supply and demand data, this report contains conversion tables intended to provide a bridge between the system used to classify occupations in the Bureau of Labor Statistics' National/State Industry-Occupation Matrix System and the system used by the Office of Education to classify occupational instructional programs. This report updates the information contained in "Tomorrow's Manpower Needs" Supplement 3 by substituting 1970 census data (occupational codes) for the 1960 base used in the earlier study. The first section outlines the characteristics of four occupational and educational classification systems: the Bureau of Labor Statistics (BLS) National/State Matrix system occupational classification; the Bureau of Census occupational classification; Dictionary of Occupational Titles (DOT) classification and codes; and the Office of Education (OE) classification. The next section describes the conversion tables including the source of data, and the construction, interpretation, and limitations of the table. The bulk of the report is the two sets of tables: (1) the Conversion of National/State Matrix titles to the vocational education classification system; and (2) vocational educational instructional programs and related National/State Matrix titles. The first lists National/State Matrix titles (e.g., each subheading under "professional, technical, and kindred workers") and corresponding 1970 census code, vocational education system code and program title, and DOT code and title. The second table then converts Matrix titles to OE instructional program codes and titles (e.g., "agricultural and biological technicians, except health") to chemical technology in the technical education program area.
