A study examined the comparative effects of major types of career information resources currently available to secondary school students on students' career awareness and career decision making. Twelve schools representing six different types of delivery systems and two levels of poverty comprised the study sample. Evaluated during the study were computer-based, experience-based, materials-based, instruction-based, publications-based, and minimal-resource delivery systems. A special instrument was designed and administered to over 100 students in each school, and interviews were conducted with from 11 to 19 students in each school. The major finding of the study was that there were no clearly discernable effects attributable to the resources available at the schools. There were also no effects attributable to the poverty level of the schools. Various recommendations were made to encourage students to use appropriate resources more frequently and effectively than they do now. Among these were calls to establish a curriculum for career decision making, to use experiential materials and programs, to improve resources for educational planning, to test materials on samples of students, and to improve computer systems.
