A study was conducted to determine the licensing and certification procedures for major State and national agencies and occupational governing bodies throughout the country. The project focused on two objectives: (1) Compilation of self-study programs leading directly to certification or licensing, and (2) development of general and specific information about licensing and certification procedures for those occupations in which vocational competence is determined through examination. The survey was conducted by mail, soliciting information on both independent study courses leading to licensure or certification and the licensure or certification procedures themselves. Information was solicited from State governmental agencies, home study schools, colleges and universities, companies, labor organizations, professional and trade organizations, and other groups and individuals. The most consistent finding was the general inconsistency among both licensing and certification agencies across States in their procedures, policies of reciprocity, and prerequisites. Information collected showed a disarray of licensing and certification procedures and policies that must be seen as impenetrable to those seeking direct ways of demonstrating their occupational competence. Evaluation of the information collected revealed that very few independent study courses lead to recognition of achievement through award of certificate, license, or academic degree. Tentative conclusions derived from the project work are discussed in detail. (TA)
