The CHHA Exam Blueprint at a Glance
Every question on the NCCT Certified Home Health Aide exam maps to one of six content areas. Understanding how these domains are structured - and how much of the exam each one occupies - is the single most useful thing you can do before you start memorizing flashcards. If you haven't already reviewed the fundamentals of eligibility and scheduling, it's worth pairing this guide with our CHHA Requirements breakdown and the CHHA Exam Dates guide before you lock in a test date.
The exam itself consists of 125 scored questions and 25 unscored pretest items seeded throughout, for a total of 150 questions in three hours. You won't know which items are scored and which are pretest, so every question deserves full attention. Format-wise, 92% of items are traditional four-option multiple choice, while the remaining 8% are drag-and-drop, multi-select, or hotspot-style questions that test sequencing and prioritization rather than simple recall.
Domain 1: Infection Prevention
Infection Prevention questions test your understanding of how pathogens spread in a home setting and what a CHHA is responsible for interrupting that spread. This domain leans heavily on procedure sequencing - hand hygiene steps, glove removal order, and when standard precautions escalate to transmission-based precautions.
Infection Prevention
Candidates must recognize contamination risks in home environments that differ from clinical settings, where sterile supplies and backup staff aren't always available.
- Hand hygiene technique and timing relative to client contact
- Proper donning and doffing sequence for personal protective equipment
- Handling of soiled linens, sharps, and biohazard waste in a home
- Recognizing early signs of infection to report to a supervising nurse
Expect scenario-based items here rather than pure definitions - the exam wants to know if you'd apply the correct precaution in a messy, real-world household situation, not just whether you can define "droplet transmission."
Domain 2: Direct Client Care
As the largest domain on the exam, Direct Client Care deserves the largest share of your prep time. This category covers hands-on tasks: vital sign measurement, basic body mechanics for repositioning, skin integrity checks, and recognizing when a client's condition has changed enough to warrant escalation.
Direct Client Care
This domain blends technical skill knowledge with judgment calls about when a task is beyond a CHHA's scope.
- Taking and recording temperature, pulse, respiration, and blood pressure accurately
- Recognizing normal versus abnormal vital sign ranges
- Basic wound and skin observation without performing clinical wound care
- Documenting and reporting changes to the care plan or supervising nurse
Because this domain is weighted so heavily, many candidates who struggle on their first attempt underestimate it. If you're trying to gauge your overall readiness, our How Hard Is the CHHA Exam? guide breaks down where most test-takers lose points, and it consistently traces back to Direct Client Care scenarios that require multi-step reasoning rather than single-fact recall.
Domain 3: Client Safety and Transfers
This domain tests your ability to move clients safely between positions - bed to chair, chair to standing, using gait belts and assistive devices - without injuring yourself or the client. It also covers fall prevention, home hazard identification, and emergency response basics.
Client Safety and Transfers
Body mechanics and hazard awareness are tested through situational prompts describing a client's mobility level and home layout.
- Proper gait belt placement and transfer technique
- Fall risk factors and environmental modifications
- Correct body mechanics to protect both aide and client during lifting
- Emergency action steps for falls, choking, or sudden medical changes
Some of the drag-and-drop and hotspot items on the exam appear in this domain, asking you to sequence transfer steps or identify hazard zones in a room image. Practicing with question formats that mimic this style - not just flashcards - is essential, which is why a full-length simulated exam like the ones on CHHA Exam Prep matters more here than in purely factual domains.
Domain 4: Activities of Daily Living
Activities of Daily Living (ADLs) covers bathing, grooming, toileting, feeding, and dressing assistance. Questions test both the "how" - proper technique for assisting without over-helping - and the "why," such as promoting client independence and dignity during personal care.
Activities of Daily Living
The exam expects you to balance safety with client autonomy, not simply perform tasks for the client.
- Safe bathing and perineal care technique
- Assisting with feeding, including aspiration risk awareness
- Dressing and grooming while preserving client independence
- Toileting assistance and incontinence care basics
ADL questions often present two similar answer choices where one preserves client dignity and independence and the other simply completes the task faster. NCCT consistently rewards the answer that respects client autonomy.
Domain 5: Special Populations
This domain addresses caregiving considerations unique to specific client groups: pediatric clients, elderly clients with dementia or cognitive decline, clients with mental health conditions, and end-of-life or hospice care. It's one of the more nuanced domains because the "correct" caregiving approach can shift dramatically depending on the population.
Special Populations
Candidates must adjust communication style, safety precautions, and care techniques based on the client's age, cognitive status, or terminal condition.
- Communication strategies for clients with dementia or memory impairment
- Recognizing signs of depression, anxiety, or behavioral escalation
- End-of-life comfort care and recognizing signs of approaching death
- Pediatric home care considerations distinct from adult care
Key Takeaway
Special Populations questions frequently test judgment about redirecting or de-escalating a confused or agitated client rather than testing medical facts - practice reading scenario tone, not just content.
Domain 6: Law and Ethics
The final domain covers scope of practice, client rights, confidentiality (HIPAA-related concepts), mandatory reporting of abuse or neglect, and documentation standards. This is a smaller domain numerically, but missing these questions often signals a candidate doesn't understand the legal boundaries of the CHHA role - a red flag employers care about.
Law and Ethics
This domain tests boundary awareness: what a CHHA is legally permitted to do versus what must be referred to a nurse or supervisor.
- Client rights, including privacy and informed consent basics
- Confidentiality requirements for health information
- Mandatory reporting obligations for suspected abuse or neglect
- Accurate, timely documentation and its legal significance

How Questions Are Actually Asked
Knowing the domains is only half the battle - you also need to know how NCCT phrases questions. Since 92% of the exam is four-option multiple choice, most items will present a client scenario followed by "What should the CHHA do first?" or "Which action is most appropriate?" These wording patterns matter because more than one answer choice is often technically correct, but only one is the best first step.
The remaining 8% of items use drag-and-drop, multi-select, and hotspot formats. Drag-and-drop items typically ask you to sequence a procedure (like PPE removal or a transfer). Multi-select items ask you to choose all correct actions from a list, meaning partial guessing is riskier. Hotspot items show an image - often a room layout or a body diagram - and ask you to click the correct zone or feature.
| Format | Share of Exam | What It Tests |
|---|---|---|
| Four-option multiple choice | 92% | Recall, prioritization, best-first-action judgment |
| Drag-and-drop | Part of 8% | Correct sequencing of procedures |
| Multi-select | Part of 8% | Identifying all correct actions in a scenario |
| Hotspot | Part of 8% | Visual identification within a diagram or image |
Because testing is closed book with no scratch paper allowed, you need to be comfortable holding vital sign ranges and sequencing steps in your head rather than jotting them down mid-exam. Practicing under those same conditions - no notes, timed - is the best way to simulate real test pressure. Our CHHA Study Guide 2026 walks through timed practice strategies specifically built around this closed-book constraint.
Turning Domain Weight Into a Study Schedule
Since Direct Client Care is the largest domain, it deserves the most calendar time. A simple way to structure a multi-week review is to front-load the heaviest domains early, when your energy and focus are freshest, and use later weeks for lighter-weight domains and full practice exams.
Direct Client Care
- Vital sign ranges and documentation practice
- Scenario drills on when to escalate to a nurse
Client Safety and Transfers + Activities of Daily Living
- Practice transfer sequencing questions
- Review bathing, feeding, and dressing technique scenarios
Infection Prevention + Special Populations
- PPE donning/doffing order drills
- Dementia and end-of-life scenario review
Law and Ethics + Full Simulated Exams
- Scope-of-practice and mandatory reporting review
- Timed, closed-book practice tests on CHHA Exam Prep
This isn't the only valid schedule - some candidates with recent hands-on experience may compress the Direct Client Care and ADL weeks and spend more time on Law and Ethics if that domain feels unfamiliar. Adjust based on where your practice test scores are weakest.
Registration, Fees, and Eligibility Mechanics
Domain knowledge only matters if you're actually eligible to sit for the exam. NCCT offers three eligibility pathways: completion of an NCCT-authorized education program, recent verified home health aide work experience, or qualifying recent U.S. military training. The experience pathway requires either six months (1,040 hours) working with multiple clients, or one year (2,080 hours) working with a single client, completed within the previous five years.
Once certified, active status must be renewed annually. CHHA-only recertification requires six continuing-education contact hours and a $40 fee. If you miss recertification for five consecutive years, the credential becomes invalid and you'd need to requalify from scratch - so don't let renewal deadlines slip. For the exact eligibility documentation you'll need to submit, our CHHA Requirements 2026 guide covers the paperwork step by step.
If you're still weighing whether this credential fits your career plans, Is the CHHA Certification Worth It? and CHHA Salary Guide 2026 cover the employment and earnings side, while CHHA Jobs outlines who typically hires certified aides - home health agencies, hospice organizations, and private-duty care companies among them.
