Home Home < Retirement and Savings Plans < University of California Retirement Plan (UCRP) < Service Credit Generally, you earn one year of service credit for a year of full-time work. Part-time or variable-time work earns a proportionate amount of service credit. For example, a member who works 50% time for one year receives one-half year of service credit. You cannot earn service credit for overtime or other work outside your normal, regular appointment.
