What makes Illinois different

  • Illinois does not issue CNA certificate numbers - employers verify you on the Health Care Worker Registry.
  • All three attempts must fall within 12 months of program completion, a tighter window than most states.
  • Aides listed through reciprocity from another state do not take the Illinois written test.

How to get certified in Illinois

  1. Complete an IDPH-approved training program (BNATP)

    Your program coordinator submits you on a roster.

  2. Create your INACE account

    You get an email and create your account with your email, SSN and date of birth - use a personal email.

  3. Pay and schedule

    Pay the $85 exam fee and choose a test date and site.

  4. Check your result on the registry

    Results post to the IDPH Health Care Worker Registry, which employers must use for verification.

Test day checklist

  • Accommodations for a documented learning disability must be requested at least 30 days before your test date.
  • If you need accommodations beyond extended time, choose a paper-based exam.

Registry and contacts

IDPH Health Care Worker Registry: 217-785-5133.

Federal minimums that apply everywhere

Federal rules set the floor for every state: nurse aide training must be at least 75 clock hours, including at least 16 hours of supervised practical training (42 CFR 483.152). States can require more. After you are certified, going 24 consecutive months without paid nursing-related work means retraining or retesting before you can work in a Medicare/Medicaid nursing home (42 CFR 483.35(d)).
