What Does CAC Mean?

What Does CAC Mean, Exactly?

CAC means Certified Alzheimer Caregiver. It's a credential specifically built for people who provide direct, hands-on care to individuals living with Alzheimer's disease and other forms of dementia. That's the whole definition - no more, no less. Because "CAC" is used as shorthand by a handful of unrelated certifications in other industries, it's worth being precise here: on this site, and in this article, CAC refers exclusively to the Certified Alzheimer Caregiver credential administered by the National Certification Board for Alzheimer Care.

If you've landed here wondering whether CAC is a broad "healthcare professional" badge or something tied to a specific facility chain, it isn't either. It's a standalone, portable certification meant to be earned by caregivers - whether they work in a memory care unit, an assisted living facility, home health, or as independent/family caregivers - who want documented proof of dementia-care competency. For a deeper breakdown of the credential itself, see our companion guide on What Is CAC Certification?

Who Issues the CAC Credential?

The Certified Alzheimer Caregiver designation is administered by the National Certification Board for Alzheimer Care (NCBAC). NCBAC maintains the candidate handbook, sets eligibility rules, and runs the exam delivery process. The most recent publicly linked candidate handbook carries a revision date of October 1, 2019, but current fees, eligibility criteria, and testing procedures are governed by NCBAC's live application and remote-testing pages rather than the older handbook - so if you're comparing numbers you find elsewhere, always defer to NCBAC's current site.

Today, exams are delivered through NCBAC's browser-based remote-proctoring process, which means candidates can test from a personal computer rather than traveling to a physical test center. That single detail changes a lot about how you should prepare, since your testing environment, equipment, and internet connection now matter as much as your content knowledge.

The Eight CAC Exam Domains

The CAC exam is built around eight official content areas, each with its own percentage range of the total 100 questions. Understanding these weights is the single most useful thing you can do before opening a single study resource, because it tells you exactly where your time is worth the most.

Because Behavior and Communication together make up roughly a third to nearly half of the exam by themselves, these are the two domains worth mastering first. For a full walkthrough of every domain with sample topics and question angles, read CAC Exam Domains 2026: Complete Guide to All 8 Content Areas.

Exam Format, Length, and Scoring

The CAC exam consists of 100 multiple-choice questions delivered in a single two-hour-and-30-minute session. There's no separate written component or practical skills demonstration - it is a straightforward, scenario-heavy multiple-choice test drawing from the eight domains above.

Scoring is where a lot of first-time candidates get confused. The CAC exam is scored on a scale of 300 to 900, and the passing threshold is 664. This is not a percentage of questions answered correctly - it's a scaled score, meaning the raw number of correct answers needed to reach 664 isn't published as a simple percentage. If you want the full mechanics of how that scaled score works and what it means for your target performance, see CAC Passing Score 2026: Exactly What You Need to Pass.

Because the format is fixed and the content is heavily weighted toward two domains, candidates who understand How Hard Is the CAC Exam? Complete Difficulty Guide 2026 tend to allocate their study time much more efficiently than those who study every domain equally.

Who Can Sit for the CAC Exam

NCBAC sets two possible eligibility paths for the CAC exam. Meeting the standard path requires all of the following:

• Age 18 or older
• Paid or unpaid direct dementia-care experience of at least 15 hours per week for one full year (reduced to six months if you are a CNA, LPN, or RN)
• At least 25 hours of dementia-care training completed within the previous two years

There is also an alternative eligibility route: candidates who are 18 or older and have participated in a Dementia Training/Apprenticeship Program may qualify without meeting the full experience threshold above. This makes the CAC accessible both to seasoned direct-care staff and to newer caregivers who've completed a structured training pathway.

For the complete breakdown of documentation requirements and how to verify you qualify before you pay any fees, see CAC Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Fees, Registration, and Remote Proctoring

The CAC exam fee is $175. Candidates who want structured content review can add NCBAC's optional Caregiver Course for an additional $500, bringing the combined total to $675. Course access lasts for 90 days or until the exam is taken - whichever happens first - so it's worth mapping your study timeline against that window before enrolling. A full cost comparison, including which candidates the course add-on tends to benefit most, is covered in CAC Certification Cost 2026: Complete Pricing Breakdown.

Because exams are delivered through browser-based remote proctoring, there is no test center to travel to - but there are hard technical requirements:

• Government-issued photo identification
• A working camera for identity and environment verification
• Reliable internet connection
• A supported device: computers and Chromebooks are accepted

Phones and tablets are not supported for remote testing, and the process requires no software installation - everything runs through the browser. If you're used to app-based testing tools, plan to test on a laptop or desktop instead. Because scheduling windows and technical setup steps can change, always check CAC Exam Dates 2026: Testing Windows, Deadlines & Scheduling before locking in a test appointment.

Who Actually Uses the CAC Credential

The CAC is designed around the realities of dementia-specific direct care rather than general nursing or clinical administration. In practice, that means the credential tends to be relevant to:

• Memory care unit staff in assisted living and skilled nursing settings
• Home health and personal care aides working specifically with dementia clients
• CNAs, LPNs, and RNs who want documented dementia-care specialization on top of their license
• Independent or family caregivers formalizing experience they've already accumulated

Because eligibility explicitly recognizes both licensed clinical staff and unlicensed direct-care workers, the CAC functions as a bridge credential - it doesn't require a nursing license, but it rewards one with a shorter experience requirement.

Building a Domain-Aware Study Plan

Generic study advice - flashcards, spaced repetition, timed practice blocks - only helps if it's pointed at the right targets. For the CAC exam specifically, that means front-loading your review on Behavior and Communication, the two heaviest domains, before spending equal time on smaller domains like Caregiver Needs or Safety.

For a more detailed, question-style breakdown of what to study each week, see the CAC Study Guide 2026: How to Pass on Your First Attempt. And if you just want a compact reference to review the night before your test, the CAC Cheat Sheet 2026: One-Page Review of Must-Know Facts summarizes the domain weights and key definitions in one page.

Keeping the CAC Current

Certification isn't a one-time event. The CAC renews annually for $35, and maintaining it requires completing six continuing-education hours per renewal cycle. Compared to the initial exam fee, renewal is a relatively small recurring cost - but it's an easy deadline to miss if you're not tracking it, so mark your renewal date as soon as you pass. Practicing with realistic multiple-choice questions on our CAC practice test platform before your initial exam can also make the whole process - from first attempt through renewal - feel far less unfamiliar.
