Basic Plan

For ERS Tier 1 Members

(Sections 70-a, 71-a and 75)

Full- and Part-Time Service

Full-Time Employment

If you join the Retirement System on the day you begin employment with a participating employer and work on a full-time, continuous basis, we calculate your retirement service credit by subtracting your beginning date of employment from the date you actually leave paid employment.

Part-Time Employment

Service credit for Tier 1 members employed less than full-time may be prorated.
