Since 1917, PSERS has been serving the public school employees of the Commonwealth of Pennsylvania. The number of individuals we serve has grown from 37,000 in 1919 to more than 600,000 today. Balancing stability and growth through prudent investment policies, PSERS' assets have grown from $6 billion in 1982 to approximately $53.5 billion as of June 30, 2017. PSERS is a defined benefit plan, a qualified trust under Section 401(a) of the Internal Revenue Service Code. To serve the increasingly complex retirement needs of our members, PSERS continues to initiate and to expand its active and retired member programs and to enhance return through a safe yet agile investment policy.
