How to Get Your CNA Certification in Wisconsin (WI): 2026 Guide

Wisconsin uses Headmaster for both its nurse aide registry and testing — a combined delivery model that keeps registration, scheduling, and renewal in one place. Every candidate must complete a 102-hour, state-approved training program before sitting for the two-part competency exam.

This guide explains what Wisconsin requires, how the Headmaster/TMU system works, how much it costs, where you can test, and how to keep your certification active.

Who oversees CNA certification in Wisconsin

The Wisconsin Department of Health Services (DHS), Office of Caregiver Quality sets the rules for nurse aide training, testing, and registry status. D&SDT–Headmaster LLP is the contracted vendor that runs both the Wisconsin TestMaster Universe (TMU) testing platform and the Wisconsin Nurse Aide Registry (WNAR). You will use a single TMU account at wi.tmutest.com to schedule exams, view results, update your demographics, and renew your certification.

Training programs in Wisconsin

Wisconsin requires completion of a DHS-approved Nurse Aide Training and Competency Evaluation Program (NATCEP). The state’s 102-hour requirement exceeds the federal 75-hour minimum and includes:

Classroom/lab instruction in infection control, resident rights, safety, communication, basic nursing skills, personal care, and the aging process.
At least 16 hours of supervised clinical training in an approved nursing facility.

Programs are offered by technical colleges, community colleges, high schools, nursing homes, home health agencies, and private CNA schools. Full-time programs usually run 4–8 weeks; part-time or evening options can take longer. Before enrolling, confirm the program is on the DHS-approved list so your completion is accepted in TMU.

Tuition ranges from $800 to $1,600, plus textbooks, scrubs, supplies, background checks, and exam fees. Some employers sponsor training or pay for testing, so ask about reimbursement when you apply for CNA jobs.

The Wisconsin CNA exam: Headmaster details

The Wisconsin Nurse Aide Competency Exam has two parts. You must pass both to be listed on the WNAR.

Knowledge test

The knowledge exam is computer-based and has 75 multiple-choice questions. You have 60 minutes to finish, and you must score 71% or better to pass. Questions come from 12 subject areas defined by DHS and federal regulations, including Aging Process and Restorative Care, Basic Nurse Skills, Care Impaired, Communication, Data Collection, Disease Process, Infection Control, Mental Health, Personal Care, Resident Rights, Role and Responsibility, and Safety.

An audio/oral version is available if you need questions read aloud. Select it when you schedule; it adds a small fee.

Skills test

The skills demonstration exam asks you to perform 3 or 4 randomly selected tasks from Wisconsin’s approved skill list within 30 minutes. Tasks are drawn from 17 possible skills, including vital signs, hand hygiene, oral care, perineal care, catheter care, transferring a resident with a gait belt, and range-of-motion exercises.

To pass, you must correctly perform all key steps and at least 80% of all non-key steps in every assigned task. You may correct a step during the test if you tell the RN Test Observer and demonstrate the correction before time runs out.

Scheduling

Your training program enters your initial TMU registration. You then log in to wi.tmutest.com, confirm your demographics, pay with a Visa or MasterCard, and select a test event and location. You can reschedule up to one full business day before your test date. If you do not show up or arrive late without notice, you forfeit your fee.

Where to take the test in Wisconsin

Headmaster schedules regional test events across Wisconsin, often at technical colleges, training program sites, and community locations. Test dates and seats are posted in the dynamic scheduler inside TMU. Many training programs also host in-facility test dates for their own graduating students.

Common testing areas include:

Milwaukee — frequent testing, large candidate volume
Madison — regular regional sessions
Green Bay — periodic scheduled events
Eau Claire — scheduled through programs and regional calendar
La Crosse — limited dates; plan ahead

Because seats fill up, schedule as soon as your instructor confirms your training completion date. If you do not see a convenient date, check back regularly or call D&SDT–Headmaster at (888) 401-0462.

Scheduling and what to bring on test day

Before test day, log in to wi.tmutest.com and confirm that your first and last name match your government-issued photo ID exactly. You must pass both exam parts within one year of finishing training or repeat a DHS-approved program.

You must bring a non-foreign, government-issued, signed, unexpired, photo-bearing ID. Accepted examples include a Wisconsin driver’s license or state ID, signed U.S. passport, permanent resident card, employment authorization card from USCIS, tribal ID from a federally recognized tribe, or U.S. military ID. Only original IDs are accepted; photocopies, screenshots, digital wallet cards, or expired IDs will make you a no-show.

Arrive in full clinical attire: scrub top and bottom (any color), closed-toed shoes, and long hair pulled back. A standard watch is allowed; smartwatches and fitness trackers are not. Be at the test site waiting area 20 minutes before your scheduled start time. If your test starts at 8:00 a.m., check-in begins at 7:40 a.m. Plan for the visit to take up to 4 hours if taking both parts.

After you pass: Wisconsin certification and renewal

Once you pass both the knowledge and skills exams, your name is added to the Wisconsin Nurse Aide Registry and you are eligible to work as a CNA. Official results are usually available in your TMU account after 7:00 p.m. Central Time on the day the test is scored.

To remain eligible to work in a federally certified facility (Medicare/Medicaid certified nursing home, home health agency, or hospice), you must renew your federal eligibility every 24 months. You can renew if you worked at least 8 hours for pay as a nurse aide during the previous 24 months, under the supervision of an RN or LPN. Self-employment and private-duty work do not count.

Renewal begins 90 days before your certification expiration date. You will receive email and SMS reminders. Log in to TMU, enter your work hours and employer, and your employer verifies the information through a secure link. If verified, your federal eligibility is extended for another 24 months.

If you do not meet the work requirement, your federal eligibility lapses and you must pass both exam parts again to regain it. You may still be listed as state-only eligible and work in state-licensed facilities that do not require federal certification.

Common pitfalls specific to Wisconsin

Headmaster runs both testing and the registry. You need a TMU account for scheduling, results, demographic updates, and renewal.
Name mismatch. If your ID does not match your TMU name of record exactly, you will be turned away as a no-show and forfeit your fee.
Wrong attire. You must wear scrubs and closed-toed shoes. Otherwise, you cannot test.
One-year deadline. You must pass both exam parts within 12 months of completing training or restart a state-approved program.
Out-of-state pre-approval. If you trained in another state, apply through TMU and receive DHS/Headmaster pre-approval before scheduling the Wisconsin exam.
Expired or digital ID. Only original, signed, unexpired, non-foreign government photo IDs are accepted.
No-show policy. Missing your exam without notifying Headmaster at least two full business days in advance means you lose your fee.

FAQ

How long does it take to become a CNA in Wisconsin? Most people finish training in 4–8 weeks, then schedule the exam within the next few weeks. From starting class to registry listing, many candidates complete the process in 2–4 months.

Do I have to complete a training program, or can I challenge the exam? Wisconsin generally requires completion of a DHS-approved NATCEP. Some nursing students, graduate nurses, and out-of-state CNAs may qualify for alternate routes, but these still require DHS/Headmaster review and approval through TMU.

What happens if I fail one part? You only need to retake the part you failed. You can schedule a retest through TMU as long as you are still within the one-year window after training.

Can I take the knowledge exam from home? Headmaster offers a remotely proctored knowledge exam option for some candidates. Check your TMU account and the Candidate Handbook for eligibility, equipment, and attire rules before choosing that option.

How do I transfer my CNA from another state to Wisconsin? You must apply for Wisconsin registry status through TMU (often called reciprocity or out-of-state transfer). If your training and exam do not automatically qualify, DHS/Headmaster may require you to pass the Wisconsin competency exam. Submit your application and supporting documents early; incomplete applications can expire.

How do I check my registry status or renew? Log in to wi.tmutest.com. You can view your status, update contact information, check your expiration date, and complete renewal employer verification there.
