A study evaluated the use of comparability of vocational training qualifications by both employers and workers in the European Community. The appropriate equivalences (joint description and comparative survey of vocational training qualifications) had been published for 16 of a total of 19 sectors or occupational groups. All Euroadvisers (n=240) were sent a standardized questionnaire in 1993; 86 usable questionnaires were returned. (Euroadvisers are members of the European Employment Service System [EURES] network.) Usable telephone interviews with approximately 100 national coordinators were conducted. Findings indicated that national experts differed as to the level of usage of the comparability system. Counseling was primarily sought by workers, students, or institutions of vocational or further training; 49 of 90 interviewees were familiar with the system of comparability; and most interviewed experts used the publications in the Official Journal of the European Union and the information sheets on individual occupations or brochures on individual occupational fields for information about the system of comparability. About half felt that the way in which the information was available was very suitable for their guidance and placement activities. In the majority of cases, informational material was used as background material for job placement or career guidance. Direct use by workers and employers had been extremely low. Workers and employers were most interested in information about certificates and practical occupational requirements. (YLB)
