A random sample of 60 ninth grade students from each of four schools in suburban areas of Chicago was obtained to ascertain student interest in vocational education, more specifically in applied biological and agricultural occupations, by means of a Career Interest Inventory. Mean item scores were obtained in order to make a comparison between scales on the Inventory. Interest in applied biographical and agricultural occupations compared favorably with industrial and health-oriented occupations. Implementation of a program in applied biological and agricultural occupations was deemed feasible because more than 10 percent of the students expressed interest in animal science, agribusiness, plant science, forestry, agricultural mechanics, and agricultural resources. Courses common to several areas should be developed, taking into account high interest in occupational areas involving forests, air, water, and recreation. Student interest in related business and office occupations was strong for most areas of specialization on the Inventory. Tables display the data. (AG)
