Educational effects of migrant student mobility are reviewed and issues and recommendations for educational continuity are offered for discussion by policymakers. Considerations for discussion of mobility are presented: continuity of age-grade level progression and education/social/health services; agency responsibility; communication requirements; uniformity of instruction; graduation requirements; assessment procedures; record-keeping; materials cross-match indexing; and coordination of instructional, counseling, and administrative components. Issues inhibiting educational continuity are identified: lack of integration of migrant educational services; need for bilingual instruction; ineffective parent advisory councils; lack of coordination among funding and service delivery agencies; problematic special education referrals; inadequate demographic data; interstate differences in competency testing and graduation requirements; inadequate records transfer; lack of communication among programs; and need for flexible programming, career guidance counseling, remedial classes, and uniform curriculum. Three recommendations call for research agenda developed by federal agencies to include needs studies, demographic data, migration patterns, nature of interschool communication, methods for meeting student needs; development of support services and remedial opportunities and innovative planning and administrative procedures; and a national interstate migrant student policy including uniform definitions of migrant students and reporting regulations, coordinated formulas for fund allocation, guides to agency and administrator responsibilities, and federal funding of program coordination and development.
