Iowa CNA Exam Prep: Requirements & Study Path
Supplemental study for Iowa nurse aide candidates. Knowledge commonly runs through Headmaster TMU (Credentia remote optional). Skills stay with Iowa community colleges or Health Tech Associates under DIAL. Confirm your route before you register.
How CNA testing works in Iowa
Typical vendor path: Headmaster / D&S Diversified. MedCertPrep is independent exam prep, not a state registry. Use the official resources section for eligibility, fees, and skills wording.
- Iowa splits knowledge and skills across different providers. Knowledge (written) registration commonly runs through Headmaster / TMU (community colleges proctor on-site; remote options include Headmaster or Credentia). Skills are not Headmaster or Credentia: take them at an Iowa community college or Health Tech Associates. Confirm your route on the DIAL CNA page before you register.
- Iowa nurse aide competency evaluation is overseen by the Department of Inspections, Appeals, and Licensing (DIAL). Complete a 75-hour approved training course, then pass both the written (knowledge) and skills exams before listing on the Iowa Direct Care Worker (DCW) Registry.
- Headmaster Iowa Candidate Handbook (confirm the live PDF): knowledge exam is typically 70 multiple-choice questions in 60 minutes. Passing is typically 70% or better. Subject-area counts come from the Iowa test plan in the handbook.
- As of January 2026, community colleges serve as knowledge proctor sites while Headmaster handles registration, payment, and records for that path. Credentia remains an alternate remote knowledge option listed by DIAL.
- DIAL materials commonly allow three attempts per exam part; after three failures on either part you typically must retake the 75-hour course and start a new testing cycle. Confirm live attempt wording on DIAL pages.
- After both parts pass, DIAL places you on the DCW Registry (allow about two weeks). Stay active with qualifying employment reporting for long-term care work.
- MedCertPrep written practice is supplemental theme prep. Iowa knowledge subject areas come from the Headmaster handbook; scored skills steps come from your Iowa skills testing site materials, not from this app.
