Student school enrollment patterns within six school districts in Texas, California, and Florida were reviewed to determine whether students classified as children of migratory agricultural workers were missing school and having their education disrupted because of their lifestyle. Using the Migrant Student Record Transfer System (MSRTS) forms, school history records, student cumulative files, and other documents pertaining to migrant program enrollment, data on school enrollments, attendance, achievement, and participation in special programs were collected for 811 migrant students, selected from the MSRTS universe of migrant students enrolled between September 1, and December 31, 1981 at each location. Representing 56% current migrants and 44% former migrants, the 811 students ranged in age from 5 to 19, with about half aged 10 or younger and two thirds enrolled in grades K-6. Data pertaining to student arrival and departure dates were collected in Washington and Michigan, two of the largest migrant receiving states. The migrant program's legislative history was also reviewed. Findings indicated that about 40% of the migrant student population within the six districts had a continuous school experience, generally within a single school district, and migrated only during the summer, over holiday breaks, or before initial school enrollment.
