Additional Service Credit (ASC) for Former Employees

ASC is cost-neutral type of service purchase. It’s more expensive than other types of service credit. The cost is different for everyone because it is based on a highest average or last salary, earliest retirement date, age and other factors.

To buy ASC, you must: 

  • have already purchased all other service credit available to you such as withdrawn, waiting period or military,
  • have 10 years of ERS service credit (not counting military service credit and unused sick/annual leave),
  • purchase in one year increments unless you have already applied for retirement and only need months to reach retirement eligibility and
  • be actively contributing to ERS at the time of purchase.

Since former employees are not actively contributing to ERS, you are not eligible to purchase this service.
