The Operating Engineers Dual Enrollment Program combines trade union apprenticeship with college study. Young persons are "dually-enrolled" by meeting both the requirements for indenture as an apprentice and matriculation as an Associate Degree candidate. Apprentices may receive college credit for apprenticeship-related training classes and for supervised work experience, amounting to one-half to three-fourths of the credits needed for an Associate Degree. An Advisory Committee was established to assess and guide the activities of the Program. Model curriculums for dually-enrolled apprentices were formulated, and two successful types of dual enrollment programs (local and regional) were initiated, serving over 2,300 apprentice operating engineers. Data on current programs and apprentices were collected to provide an ongoing assessment of progress. Linkages between Associate Degree programs and 4-year degree programs were initiated and are being further developed. The Program will be continued under the sponsorship of the International Union of Operating Engineers. The body of the report includes (1) description of objectives and methodology of the project, (2) descriptions of program development, curriculums, and problems in the various local programs and in a regional program established in cooperation with Dickinson State College, North Dakota, (3) discussion of results in terms of enrollees and assessment by unions, contractors, and colleges, and (4) recommendations for the future of the program. Appendixes (half of the report) include samples of supplementary evaluation reports on individual projects; lists of work processes (tasks) for universal equipment operator, paving equipment operator, plant equipment operator, and heavy duty repairman; several degree program schedule outlines for dual enrollment programs; and a directory of universities and colleges offering programs in labor studies and in construction.
