The purpose of this legislation, known as the "Parity for Tribal Educators Act," is to ensure that employees working at tribally controlled schools can access retirement benefits similar to those available to federal employees. Specifically, it aims to allow these educators to participate in the Federal Employees Retirement System (FERS) and the Thrift Savings Plan (TSP). Key provisions of the Act include the classification of employees at tribally controlled schools as federal employees for retirement purposes.
