Hearing Instrument Dispensing Certificate Program

Welcome to the College of DuPage Hearing Instrument Dispensary Certificate Program. The Hearing Instrument Dispensary Certificate will prepare students for a career as a hearing healthcare provider and hearing instrument specialist. This program will prepare hearing healthcare providers to administer and interpret hearing tests, select and fit hearing aids, adjust physical and electroacoustic parameters of hearing instruments, and recommend assistive listening devices.

This program will help prepare students for the Illinois Department of Public Health Hearing Instrument Dispenser Licensing Written and Practical Exams.
