Full- and Part-Time Service Credit

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.

For Tier 2 members, part-time employment is credited as the lesser of:

number of days worked ÷ 260 days


annual salary reported ÷ (State’s hourly minimum wage × 2,000)

Employers report your days worked and salary to us.
