The Vocational Instructional Materials Acquisition System (VIMAS) was developed in Florida to facilitate the establishment of competency-based vocational programs through dissemination of instructional mateials. VIMAS is a comprehensive system of components which work interdependently from the identification of needs to the dissemination and diffusion of the products. System components include decision making; needs assessment and prioritization; search for existing materials or reproducing materials; dissemination and diffusion of materials; and evaluation and revision of the VIMAS system. Hundreds of vocational teachers and supervisors were involved in developing these components and defining the competency-based characteristics of the materials that were to be entered into the system. The system is geared to acquiring both curricular and instructional materials, which makes it possible to deliver comprehensive packages of materials that, with some modification for local needs, could form the basis for the core of an instructional program; such a core could eliminate a great deal of additional work to develop materials. A cost analysis of 10 VIMAS projects showed that Florida acquired materials which cost original developers $3,408,053 for $261,858 by using VIMAS procedures--approximately 7.5 percent of the cost of developing the materials.
