PUNS can be completed for any individual in Illinois with a developmental disability who has an unmet service need anticipated in the next 5 years. After initially meeting with an Independent Service Coordinator Agent (ISC) the PUNS must be updated annually, anytime a need for service changes, when contact information changes, or when caregiver information changes. Failure to update annually with your ISC Agent will result in removal of your service need from the waiting list. Updating is often a quick process, and the only way to be selected for funding for services is to be on the list!
