Teachers' Retirement System
The New York State Teachers' Retirement System (NYSTRS) was established by the Legislature in 1920 (chapter 503). In 1947 (chapter 820), the laws creating the system and enumerating the powers of its board of trustees were re-codified as Article 11 of the Education Law. This article, along with Section 177 of the Retirement and Social Security Law give the Board its principle authority to invest the system's funds.
