Step-by-step explanation:
In the context of school training records, the duration for which individual student training records must be maintained by the school may vary depending on federal and state regulations, as well as local policies. However, as per the guidelines provided by the U.S. Department of Education, schools are typically required to maintain these records for a minimum of five years after the student has left the school or graduated.
