The Migrant Student Information Exchange (MSIX) is the technology that allows states to share educational and health information on migrant children who travel from state to state and who, as a result, have student records in multiple states' information systems. MSIX works existing migrant student information systems that states currently use to manage their migrant data to fulfill its mission to ensure the appropriate enrollment, placement, and accrual of credits for migrant children nationwide.

The use of MSIX improves the timeliness of school enrollments, improves the appropriateness of grade and course placements, and reduces incidences of unnecessary immunizations of migrant children. Further, MSIX facilitates the accrual of course credits for migrant children in secondary school by providing accurate academic information on students' course history and academic progress. Of key importance, states are able to notify each other when a migrant student moves to a different state.
