The purpose of this study was to determine to what degree public school districts with heavy migrant populations utilize the services of the Migrant Student Record Transfer System (MSRTS), and to identify and describe some factors which may influence future use of the MSRTS in 5 states. An original questionnaire was developed and administered by mail to school districts participating in the MSRTS and to those school districts identified as potentially eligible and not participating in the MSRTS. Responses to questionnaire items were analyzed using chi-square and analysis of variance. Descriptive data were also presented. The school districts were divided into 3 groups: Group I--using MSRTS and having a terminal physically located in the district; Group II--using MSRTS but not having a terminal; and Group III--potentially eligible for participation and lacking terminals. Findings concluded that there were significant differences in high, medium, and low usage among the groups and that the size of the school district was not a factor. (Author/PS)
