Focusing on the roles of organized interest groups and cooperative alliances in constructing a migrant/mobile education system, this paper analyzes the major policy struggles encountered in building the migrant education program during its first 14 years and points out the program's direction for future growth. After a discussion of the basic problems in migrant education, the paper focuses on the impact of various national religious groups, voluntary and professional organizations, and the farm lobby on the development and passage of migrant education legislation. The paper reviews some of the problems and challenges encountered in building an effective delivery system for migrant/mobile education, e.g., identification and recruitment of migrant students and program coordination and continuity. Next, there is a discussion of the struggle over policy control from 1966 to 1974 and the mobilization of support from sources both external and internal to government. The next section highlights the confrontations involving migrant education between 1975 and 1978. The conclusion points out that migrant education must now expand more vigorously into the secondary and postsecondary education fields and indicates the likely areas of confrontation. (CM)
