A new Iowa Career Education Inventory was developed to be technically sound and responsive to career education objectives defined in the Articulation Guide for Career Education. Four levels of the inventory were developed to measure instructional objectives of stages in career development: (1) awareness represented concepts taught in kindergarten through grade three, measured in third grade; (2) accommodation represented concepts taught in grades four through six, measured in grade six; (3) exploration represented concepts taught in grades seven through nine, measured in grade nine; and (4) preparation represented concepts taught in grades ten through twelve, measured in grade twelve. Each level included seven content domains. Self, Interpersonal Relationships, and Self and Society focused on understanding the relationship between personal and affective characteristics and career development. Decision Making Skills, Economics, Occupational Knowledge, and Work Values and Attitudes focused on the cognitive components of career development. Field test data should be further analyzed to examine the impact of forming composite scores. This instrument should be useful in assessing the appropriateness and effectiveness of integrating career education concepts into classroom instruction for grades three to twelve. (DWH)
