- You need a scaled score of 575 on NCCT's 200-720 scale to pass, not a raw percentage.
- Direct Client Care is the largest of the six domains - prioritize it in your study plan.
- The exam has 125 scored items plus 25 unscored pretest items, all within a three-hour window.
- 92% of questions are four-option multiple-choice; the remaining 8% use drag-and-drop, multi-select, and hotspot formats.
Understanding the NCCT CHHA Exam Format
Before you open a single flashcard, you need to know exactly what you're preparing for. The Certified Home Health Aide exam is administered by the National Center for Competency Testing (NCCT), either at an authorized test site or through live remote proctoring. That choice matters for your study plan because remote testing carries its own logistics - quiet room, working webcam, valid ID - on top of the content itself.
The exam itself is not a quick quiz. NCCT's November 2024 detailed test plan lays out 125 scored items and 25 unscored pretest items, for a total of 150 questions delivered within a three-hour testing window. Those 25 unscored items are mixed in without being labeled, so you cannot skip effort on any question just because it "feels experimental." Pacing across three hours means you have roughly 72 seconds per question if you want breathing room to review flagged items at the end.

Registration, Fees, and Eligibility Mechanics
The CHHA exam fee is $70, and if you choose the live remote-proctoring option, expect an additional $44 remote-testing fee. Budgeting for both up front avoids a surprise charge on exam registration day. If you want the complete cost picture - including renewal fees and optional prep expenses - our CHHA Certification Cost 2026: Complete Pricing Breakdown guide walks through every line item.
Eligibility to sit for the exam runs through one of three pathways:
- NCCT-authorized education pathway: completion of an approved home health aide training program.
- Verified work experience: six months or 1,040 hours of home health aide experience with multiple clients, or one year (2,080 hours) with a single client, both within the previous five years.
- Qualifying recent U.S. military training: relevant medic or caregiver training completed within an eligible timeframe.
The experience pathway trips up a lot of candidates who assume any caregiving job counts. It has to be verifiable, recent (within five years), and it has to meet the hour threshold for either the multi-client or single-client track. If you're unsure which pathway applies to you, our full CHHA Requirements 2026: Eligibility, Prerequisites & How to Qualify guide breaks down documentation requirements in detail.
Key Takeaway
Confirm your eligibility pathway and gather documentation (training certificate or employer-verified hour logs) before you register - not after. Eligibility disputes can delay your test date by weeks.
Domain-by-Domain Study Priorities
The CHHA exam is built around six domains, and they are not weighted equally. Direct Client Care is explicitly the largest category, which means it deserves the largest share of your study hours - not an equal one-sixth split across all six areas.
Domain 1: Infection Prevention
Covers standard precautions, hand hygiene technique, PPE donning/doffing sequence, and safe handling of contaminated materials in the home setting.
- Know the difference between standard precautions and transmission-based precautions
Domain 2: Direct Client Care
The largest domain on the exam. Expect heavy coverage of vital sign monitoring, observing and reporting changes in condition, basic body mechanics for care tasks, and following a client's care plan accurately.
- Prioritize this domain first - it carries the most scored items
Domain 3: Client Safety and Transfers
Focuses on fall prevention, safe transfer and ambulation techniques, use of assistive devices, and emergency response basics in a home environment.
- Memorize proper gait belt and transfer sequencing - these show up as scenario questions
Domain 4: Activities of Daily Living
Bathing, grooming, toileting, feeding, and mobility support - with an emphasis on promoting client independence rather than doing tasks for them.
- Expect questions that test whether you know when to assist versus when to step back
Domain 5: Special Populations
Care considerations for pediatric, geriatric, hospice/end-of-life, and cognitively impaired clients - each with distinct communication and safety needs.
- Dementia and hospice care scenarios are common sources of nuanced test items
Domain 6: Law and Ethics
Client rights, confidentiality (HIPAA-related concepts), scope of practice boundaries, abuse/neglect reporting obligations, and documentation standards.
- Know exactly what falls outside a home health aide's legal scope of practice

How CHHA Questions Are Actually Written
NCCT writes the vast majority of CHHA questions - 92% of them - as straightforward four-option multiple-choice items. But "straightforward" doesn't mean easy. Most are scenario-based: you're given a short client situation and asked what the aide should do next, what to report, or what falls outside your scope. This is a competency exam, not a memorization quiz, so studying isolated vocabulary terms without context will leave gaps.
The remaining 8% uses drag-and-drop sequencing (think: ordering the steps of a transfer or a PPE removal sequence), multi-select items where more than one answer is correct, and hotspot questions where you click a specific area of an image. These formats appear far less often, but because they're unfamiliar to most candidates, even a small number of practice repetitions pays off disproportionately.
If you want to gauge your current readiness against realistic question formats before test day, running through timed practice sets on our CHHA practice test platform is the fastest way to find out where your scenario-reasoning skills actually stand versus where you assume they stand.
A CHHA-Specific Study Timeline
Generic study techniques like spaced repetition or focused review blocks only help if you're applying them to the right material at the right time. Here's a domain-weighted four-week structure that reflects the CHHA exam's actual emphasis.
Direct Client Care + Infection Prevention
- Start with Direct Client Care since it's the largest domain
- Layer in Infection Prevention basics - PPE sequencing, hand hygiene
- Take a baseline practice set to identify weak areas early
Client Safety and Transfers + Activities of Daily Living
- Drill transfer sequencing using drag-and-drop style practice items
- Review ADL scenarios focused on promoting client independence
Special Populations + Law and Ethics
- Study dementia, hospice, and pediatric care distinctions
- Memorize scope-of-practice boundaries and reporting obligations
Full-Length Practice and Timing
- Run full 150-item timed practice exams to build three-hour stamina
- Re-review any domain scoring below your target on practice tests
Notice that Direct Client Care appears first because it's the largest domain, and full-length timed practice is saved for the final week once content review is largely complete.

Test Day Mechanics You Can't Improvise
A few operational details catch first-time candidates off guard:
- No scratch paper: Plan for this during practice, not on exam day. If your practice test platform allows note-taking, wean yourself off it in your final week.
- Three-hour hard limit: With 150 total items (scored plus unscored), budget your pacing so you're not rushing the last 20 questions.
- Remote proctoring logistics: If you're testing remotely for the $44 fee, test your camera, internet connection, and room setup the day before - not the morning of.
- Passing threshold: You need a scaled score of 575 on NCCT's 200-720 scale. This is not a percentage-correct calculation, so don't try to estimate your score by counting correct answers as you go. Our CHHA Passing Score 2026: Exactly What You Need to Pass article explains how the scaled scoring actually works.
If you're still finalizing when to schedule, availability and deadlines vary by testing method - check our CHHA Exam Dates 2026: Testing Windows, Deadlines & Scheduling guide so you don't lose eligibility momentum waiting too long between finishing training and sitting for the exam.
Key Takeaway
Practice under real exam conditions - no notes, three-hour block, mixed question formats - at least once before test day so the format itself isn't a source of surprise.
After You Pass: Recertification Reality
Passing is not a one-time event - CHHA active status renews annually. For CHHA-only recertification, you'll need six continuing-education contact hours plus a $40 fee each cycle. Miss five consecutive recertification years, and the credential becomes invalid, meaning you'd have to requalify from scratch through one of the original eligibility pathways.
This is worth planning for before you even take the initial exam, since it affects the long-term value of the credential. If you're weighing whether the investment of time and fees is worthwhile relative to job opportunities, our Is the CHHA Certification Worth It? Complete ROI Analysis 2026 piece and CHHA Salary Guide 2026: Complete Earnings Analysis lay out the practical considerations. Home health agencies, hospice organizations, and private-duty care companies are the primary employers seeking this credential - you can browse current openings and typical employer expectations in our CHHA Jobs overview.
