The Association of Public Pension Fund Auditors (APPFA) was established in 1991 by four internal auditors from public pension funds in Colorado, Illinois, New York, and Wisconsin.

Since then, APPFA has grown to over 100 member organizations, including the largest public employee retirement systems in 40 states and Canada. Its members are comprised predominately of public employee retirement systems, including state, municipal, and teacher plans. The membership meets twice annually in the spring and fall seasons. APPFA is a non-profit, tax-exempt 501(c)(3) organization incorporated in the state of New York.
