Description The Teachers' Retirement System of Oklahoma (TRS) is undertaking a comprehensive, multiyear modernization initiative to replace aging legacy systems—including full retirement of the ALICE platform—and transition to a unified, cloud-native environment. This effort centers on building MyPAS 3.0, a modern Azure-hosted pension administration system that integrates seamlessly with MyTRS and MyERS. TRS serves a large and diverse membership of over 210,000 employees and retirees across more than 600 school districts, career tech centers, colleges, and universities, making it the largest of Oklahoma's six state pension systems.
