Based on the procedures, materials, and resources used in "A Study of the Feasibility of Vocational Modules", this manual is one of the products of the study. Since guidelines for feasibility studies in the areas of public services that relate to human behavior are not clearly defined, it is hoped that this manual will guide, support, and lessen the efforts of other practitioners contemplating such studies. Procedures used by the Navajo Division of Education and American Institutes for Research in designing a vocational education curriculum for a community school serving Indians in Navajo, New Mexico, are generalized for more universal use. The major tasks selected as fundamental to a feasibility study are: (1) determination of goals and conditions; (2) identification of people and agencies; (3) analysis of resources available; (4) review of previous studies; (5) use of advisory committee(s); (6) collection of data; (7) analysis of data; (8) interpretation of data; (9) formulation of conclusions and recommendations; (10) statement of feasibility; and (11) time/task/responsibility chart. These tasks are fully described. Attention is given to the problems encountered; suggestions for solving the problems are provided. (NEC)
