HB 1097 -- Public School Retirement System Sponsor: Denison This bill allows a retired teacher to work between 550 and 800 hours in a certified staff position without losing his or her retirement benefit under the Public School Retirement System. The teacher may earn up to 75% of the annual compensation for that position but will not contribute to the retirement system during the period of service. However, the district will be required to contribute the regular contribution percentage based on the wages earned. No service credit will be accrued by the person.Copyright (c) Missouri House of Representatives
