Under the SERS umbrella there are 3 different plan options. Two "hybrid" plans where a portion goes to a defined benefit plan that features guaranteed monthly payments and a portion goes to a defined contribution plan where the amount of money you earn depends on the performance of your investments. The third option is a straight defined contribution/investment plan.
There are a few exceptions related to campus police including patrol officer, police specialist, police supervisor, police chief, or assistant police chief. View the campus police retirement page for the retirement plan options available to campus police.
