What Is A CHHA?

What Is a CHHA?

A Certified Home Health Aide, or CHHA, is a caregiver who has demonstrated competency in personal care, safety, and basic health support tasks by passing a standardized national examination administered by the National Center for Competency Testing (NCCT). The credential signals to employers, agencies, and regulators that the aide can be trusted to work in a client's home with reduced direct supervision, handling everything from bathing and mobility assistance to recognizing signs of medical decline.

Unlike an informal on-the-job title, "CHHA" is a specific, testable certification. Passing the exam means the aide has been evaluated across six defined content areas that mirror the real responsibilities of home-based caregiving. If you're weighing whether this credential fits your career plans, the deeper analysis in Is the CHHA Certification Worth It? Complete ROI Analysis 2026 walks through the trade-offs in more detail.

Who Hires CHHAs and Where They Work

CHHAs are typically employed by home health agencies, hospice organizations, private-duty care companies, and sometimes directly by families managing long-term or post-acute care for a relative. Because the certification is portable and nationally recognized through NCCT, it often satisfies state or employer requirements more efficiently than an uncertified aide role.

Day-to-day work varies by client but generally falls into the same categories tested on the exam: assisting with activities of daily living, monitoring and reporting changes in a client's condition, following infection control protocols, and supporting safe transfers and mobility. Aides working with pediatric clients, clients with dementia, or clients receiving end-of-life care fall under the exam's Special Populations content as well.

How the CHHA Exam Is Built

The CHHA exam is administered by NCCT at authorized testing sites and also via live remote proctoring, which gives candidates flexibility if a local test center isn't convenient. Understanding the exam's format matters just as much as knowing the content, because the question styles are deliberately varied.

• Total items: 125 scored questions plus 25 unscored pretest items (150 total), based on the November 2024 detailed test plan.
• Time allowed: Three hours to complete the exam.
• Question format: 92% are traditional four-option multiple-choice items; the remaining 8% use drag-and-drop, multi-select, and hotspot formats.
• Testing conditions: Closed book, with no scratch paper permitted during the exam.

The unscored pretest items are mixed in with scored questions and look identical, so there's no way to identify or skip them - every question should be treated as if it counts. This structure and pacing is broken down further in How Hard Is the CHHA Exam? Complete Difficulty Guide 2026, which is useful if you want a realistic sense of exam pressure before test day.

The Six CHHA Exam Domains

The exam content is organized into six domains, each representing a cluster of real-world caregiving responsibilities. Direct Client Care is the largest category, reflecting how much of an aide's actual workday is spent on hands-on tasks rather than administrative or peripheral duties.

Eligibility Pathways Explained

Before you can sit for the exam, you need to qualify through one of three routes recognized by NCCT:

1. Education pathway: Completion of an NCCT-authorized home health aide education program.
2. Experience pathway: Recent verified home health aide work experience - either six months (1,040 hours) with multiple clients, or one year (2,080 hours) with a single client, completed within the previous five years.
3. Military pathway: Qualifying recent U.S. military training relevant to home health aide duties.

The experience pathway is often the most misunderstood, since candidates sometimes assume any prior caregiving work counts. It has to fall within the five-year lookback window and meet the hour thresholds exactly as specified. A full walkthrough of documentation and edge cases is available in CHHA Requirements 2026: Eligibility, Prerequisites & How to Qualify, and if you're still building hours or completing coursework, CHHA Training outlines what qualifying programs typically include.

Registration, Fees, and Test-Day Rules

The standard CHHA exam fee is $70. Candidates who test via live remote proctoring instead of an in-person authorized site pay an additional $44 remote-testing fee. Choosing between the two comes down to convenience versus access to a physical test center near you.

On test day, the exam is closed book and no scratch paper is allowed, so any mental math, sequencing, or notes have to happen entirely in your head or through the on-screen tools provided. This is a meaningful difference from exams that allow scratch paper for calculations or lists, and it's worth practicing without any aids during your prep.

Scoring and the 575 Passing Standard

NCCT scores the CHHA exam on a scale of 200 to 720, and candidates need a scaled score of 575 to pass. Because the score is scaled rather than a raw percentage, the number of questions you need to answer correctly can shift slightly depending on the difficulty weighting of the specific form you receive - this is standard practice for competency exams and is designed to keep results comparable across different test administrations.

Since Direct Client Care carries the most weight on the test plan, a shortfall in that domain is harder to offset with strength elsewhere. A detailed explanation of how the scale works and what it means for study priorities is available in CHHA Passing Score 2026: Exactly What You Need to Pass, and outcome trends are discussed in CHHA Pass Rate 2026: What the Data Shows.

Mapping Your Prep to the Test Plan

Rather than studying domains in random order, it makes sense to sequence your review around how heavily each domain is weighted and where your own experience is weakest. Since Direct Client Care is the largest domain, it deserves the most calendar time; Law and Ethics and Infection Prevention are typically faster to review since they involve more fixed rules and less situational judgment.

A short daily review session tends to work better than occasional long cram sessions, especially for a domain-heavy exam like this one - but the schedule above should flex based on which domains feel weakest after your first practice test. For a more complete week-by-week plan with additional milestones, see CHHA Study Guide 2026: How to Pass on Your First Attempt. You can also build familiarity with the question formats directly through practice exams on the main practice test site.

Keeping the Credential Active

Passing the exam is only the starting point - the CHHA credential requires ongoing maintenance. Active status renews annually, and CHHA-only recertification requires six continuing-education contact hours along with a $40 fee. If five consecutive recertification years are missed, the credential becomes invalid and would need to be re-earned from scratch.

This annual cadence means it's worth building a simple system for tracking your CE hours rather than scrambling near a deadline. Employers frequently ask to see current certification status, so staying on top of renewal protects both your job standing and the time you already invested in What Is CHHA Certification? and the exam itself.

If you're still deciding whether to pursue the credential in the first place, background pieces like What Is A CHHA?, What Does CHHA Mean?, and What Is CHHA? cover the fundamentals from slightly different angles, while CHHA Certification gives a broader overview of the process end to end. When you're ready to start testing your knowledge against realistic question formats, practice tests built around the current NCCT test plan are the most direct way to gauge readiness.
