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.
Service credit may be prorated for Tier 1 members employed on a less than full-time basis. For Tier 2, 3, 5 and 6 members, part-time employment is credited as the lesser of:
number of days worked ÷ 260 days
annual earnings reported ÷ (State’s hourly minimum wage × 2,000)
Employers report days worked and earnings to us.
