If you work a minimum of 20 hours/week for 20 or more weeks of the year with a NDPERS employer, are at least eighteen years of age, and filling a permanent regularly funded position, you must participate unless you are eligible to opt out or special provisions apply.
If you are an eligible part-time or temporary employee with a NDPERS employer, you may elect to participate at your own expense within the first 180 days of beginning employment.
Every month you contribute to your NDPERS retirement plan, you earn service credit.
Your lifetime, monthly benefit is calculated based on a formula. Some of the factors in the formula may differ for participants based on their enrollment and retirement dates.
