CNA — Certified Nursing Assistant in Illinois
IL Dept. of Public Health — Health Care Worker Registry
Illinois is unusual: instead of a national vendor (NNAAP/Prometric/Headmaster), the CNA written competency exam is administered by Southern Illinois University (SIU) Carbondale through INACE, under the Illinois Department of Public Health. The test is in English, scored pass/fail (the cut score isn't publicly disclosed). The fee is a flat $85 that covers a 12-month testing period, with 3 attempts in those 12 months. Aides are listed on the IDPH Health Care Worker Registry. Our practice bank is trilingual for study support; the Illinois exam is in English.

Vendors, fees, pass marks and language options vary by state and change over time — fields marked “To confirm” are not yet source-verified, and you should always confirm with your state's nurse aide registry before testing. We never imply you can take the exam in a language your state does not actually offer.
