What CHHA Actually Means
CHHA stands for Certified Home Health Aide. It's the credential you earn after completing an eligibility pathway and passing a standardized exam administered by the National Center for Competency Testing (NCCT). The letters themselves are simple, but the process behind them is not - it involves documented training or experience, a proctored exam with a specific structure, and an ongoing recertification obligation once you're certified.
If you're still sorting out terminology, our companion pieces on CHHA Meaning, What Does CHHA Stand For?, and What Does CHHA Mean? break down the acronym from different angles. This article focuses on what the credential involves in practice - the exam, the domains, and the mechanics of getting certified.
Who Hires CHHAs and Why the Credential Matters
Home health agencies, hospice organizations, and private-duty staffing firms typically require or strongly prefer candidates who hold a CHHA credential rather than an uncertified aide title. The certification signals that a candidate has been tested on standardized content - infection control, safe transfers, activities of daily living, and more - rather than relying solely on informal on-the-job training.

How the CHHA Exam Is Built
The CHHA exam is administered by NCCT, either at an authorized test site or through live remote proctoring. Understanding the exam's structure matters more than most candidates expect, because the format itself shapes how you should study.
- 125 scored items plus 25 unscored pretest items, for 150 total questions on the November 2024 detailed test plan.
- Three hours allotted for the full exam.
- 92% four-option multiple-choice questions, with the remaining 8% split across drag-and-drop, multi-select, and hotspot item types.
- The test is closed book, and no scratch paper is permitted - all reasoning happens on-screen and in your head.
The unscored pretest items are mixed in with scored questions without being labeled, so there's no way to identify or skip them. Treat every question as if it counts. The presence of drag-and-drop, multi-select, and hotspot formats also means memorized single-answer recall isn't enough - you need to be comfortable manipulating information, not just recognizing it. For a full breakdown of what makes the exam challenging (or manageable), see How Hard Is the CHHA Exam? Complete Difficulty Guide 2026.
Key Takeaway
Because 8% of questions use non-traditional formats like hotspot and multi-select, practice tests that only offer standard multiple-choice won't fully prepare you for the actual interface.
The Six Domains You'll Be Tested On
NCCT organizes the CHHA exam content into six domains. Each one represents a distinct slice of the job, and the exam weights them unevenly - some categories carry far more questions than others.
Domain 1: Infection Prevention
Covers standard precautions, hand hygiene, personal protective equipment, and how to prevent the spread of pathogens in a home setting where controls are less standardized than in a hospital.
- Know the difference between standard and transmission-based precautions
- Understand proper disposal of contaminated materials in a home environment
Domain 2: Direct Client Care
This is the largest category on the exam, covering the hands-on tasks aides perform most frequently - vital signs, personal care assistance, and observing/reporting changes in client condition.
- Prioritize this domain in your study schedule given its size
- Focus on recognizing abnormal findings and appropriate reporting procedures
Domain 3: Client Safety and Transfers
Addresses body mechanics, safe transfer techniques, fall prevention, and emergency response basics in the home.
- Understand proper positioning and use of assistive devices
- Know when a situation requires escalation beyond the aide's scope
Domain 4: Activities of Daily Living
Covers assistance with bathing, dressing, feeding, toileting, and mobility - the core daily tasks that support a client's independence and dignity.
- Distinguish between tasks an aide can assist with versus tasks requiring a licensed professional
Domain 5: Special Populations
Focuses on care considerations for pediatric, geriatric, cognitively impaired, and other client groups with distinct needs.
- Study how care approaches shift based on age and condition
Domain 6: Law and Ethics
Covers client rights, confidentiality, scope of practice, and the legal boundaries of the home health aide role.
- Know what falls outside your scope of practice and how to respond appropriately
Because Direct Client Care carries the most weight, it deserves the largest share of your study time. For a domain-by-domain study plan with more granular subtopics, see CHHA Exam Domains 2026: Complete Guide to All 6 Content Areas.
Eligibility Pathways Explained
Before you can sit for the CHHA exam, you need to qualify through one of three routes:
- NCCT-authorized education pathway - completing an approved home health aide training program.
- Verified recent work experience - either six months or 1,040 hours working with multiple clients, or one year or 2,080 hours working with a single client, completed within the previous five years.
- Qualifying recent U.S. military training - relevant training completed through military service.
The experience pathway is often overlooked by people who assume certification requires formal schooling, but it's a legitimate and commonly used route for aides who've been working informally. Full details on documentation and verification are covered in CHHA Requirements 2026: Eligibility, Prerequisites & How to Qualify.
| Pathway | Requirement |
|---|---|
| Education | Completion of NCCT-authorized training program |
| Experience (multiple clients) | 6 months or 1,040 hours within the last 5 years |
| Experience (single client) | 1 year or 2,080 hours within the last 5 years |
| Military | Qualifying recent U.S. military training |
Registration, Fees, and Test-Day Logistics
Once eligibility is confirmed, registering for the exam involves a few fixed costs and choices. The standard exam fee is $70. If you opt for live remote proctoring instead of testing at an authorized site, an additional $44 remote-testing fee applies.
On test day, remember the exam is closed book with no scratch paper allowed - plan your time management strategy around working problems mentally or on-screen rather than jotting notes. A full cost breakdown, including recertification fees and optional training expenses, is available in CHHA Certification Cost 2026: Complete Pricing Breakdown.

Scoring and What 575 Really Means
NCCT scores the CHHA exam on a scale from 200 to 720. To pass, you need a scaled score of 575. This isn't a raw percentage of questions answered correctly - it's a scaled score that accounts for the specific mix of items on your version of the exam.
Because the passing threshold is fixed on this scale rather than expressed as "70% correct" or similar, candidates sometimes misjudge how close they are to passing based on gut feeling alone. For a precise explanation of how scaled scoring works and what it means for your prep, read CHHA Passing Score 2026: Exactly What You Need to Pass. If you want a broader sense of how candidates generally perform, CHHA Pass Rate 2026: What the Data Shows covers that in detail.
Keeping Your CHHA Active
Certification isn't a one-time event. CHHA status renews annually, and CHHA-only recertification requires six continuing-education contact hours plus a $40 fee each cycle.
Building a habit of tracking your CE hours annually is far easier than scrambling before a deadline or, worse, letting the credential lapse past the point of recovery.
Mapping Your Prep to the Test Plan
Because Direct Client Care carries the most exam weight, it makes sense to structure your study time around domain size rather than splitting hours evenly across all six categories. A simple approach: spend roughly twice as much time on Direct Client Care as on any single smaller domain, and use short, focused review sessions rather than marathon cramming - especially since the exam includes non-multiple-choice formats that reward comfort with the interface, not just memorized facts.
Direct Client Care & Infection Prevention
- Drill vital signs, personal care tasks, and standard precautions
- Practice hotspot and multi-select style questions on these topics
Client Safety, Transfers & ADLs
- Review body mechanics and safe transfer sequences
- Practice distinguishing aide-appropriate tasks from those outside scope
Special Populations & Law and Ethics
- Study care variations across age groups and conditions
- Review client rights, confidentiality, and scope-of-practice boundaries
Full Review & Timed Practice
- Take full-length timed practice exams under closed-book conditions
- Revisit weak domains identified during practice testing
