Missouri CNA Exam Prep: Requirements & Study Path
Supplemental study for Missouri nurse aide candidates on the Headmaster / D&S Diversified pathway. Confirm TMU scheduling, Candidate Handbook subject areas, skills tasks, and DHSS CNA Registry steps on official pages.
How CNA testing works in Missouri
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.
- Missouri nurse aide testing is administered by D&S Diversified Technologies (Headmaster). It is not Credentia NNAAP and not Prometric.
- Create and complete your record in the Missouri TestMaster Universe (TMU) portal, pay testing fees, then schedule knowledge and skill exams per the current Candidate Handbook.
- Knowledge exam: typically 75 multiple-choice questions in 60 minutes, drawn from Headmaster handbook subject areas. Passing is typically 80% or better; confirm live score wording in the current PDF.
- Skill test: you demonstrate assigned tasks from the Missouri skills list. Bold critical/key steps must be correct, and you must also meet the handbook's non-key step threshold. Confirm live task count and timing in the current handbook.
- After you pass both parts, registry status is commonly managed through Headmaster TMU and Missouri Department of Health and Senior Services (DHSS) CNA Registry pages. Confirm renewal and lookup steps on DHSS.
- MedCertPrep written practice is supplemental theme prep; Missouri subject areas and scored skills steps still come from Headmaster and DHSS materials.

Study on MedCertPrep
Missouri knowledge items follow the Headmaster Candidate Handbook subject areas (typically 75 questions in 60 minutes). MedCertPrep practice is NNAAP-structured supplemental prep for overlapping nurse aide themes (ADLs, safety, infection control, rights, reporting). It is not a Headmaster clone bank. Scored skills steps come only from the official Missouri handbook task list.
