CAC Exam Domains 2026: Complete Guide to All 8 Content Areas

Overview: What the 8 CAC Domains Represent

The Certified Alzheimer Caregiver (CAC) exam, administered by the National Certification Board for Alzheimer Care (NCBAC), is organized into eight official content areas. Each domain carries a published percentage range that tells you roughly how many of the 100 scored questions will come from that topic. Understanding these ranges is the single most useful thing you can do before you start studying, because it tells you where to spend your limited prep time.

Unlike generic certification content that treats "exam domains" as an abstract checklist, the CAC domains map directly onto the real, daily work of caring for someone living with Alzheimer's disease or another dementia. Questions are written from the perspective of a hands-on caregiver - someone managing agitation at 4 p.m., redirecting a resident who wants to "go home," or explaining a change in condition to a family member. If you want the full mechanics of how the test is delivered and scored, see our companion piece on CAC Exam Domains 2026: Complete Guide to All 8 Content Areas, and pair it with the broader CAC Study Guide 2026: How to Pass on Your First Attempt for a full prep roadmap.

The 8 Content Areas Ranked by Weight

Here is the complete list of official CAC content areas, ranked from heaviest to lightest weighting on the exam:

Notice how the top four domains - Behavior, Communication, Knowledge of Disease, and Activities - together account for the large majority of the exam's content weight. That's not a coincidence; it reflects what actually matters most in day-to-day dementia care. A candidate who deeply understands disease progression, behavioral triggers, and how to communicate with someone experiencing cognitive decline is far better positioned to pass than someone who memorizes isolated facts about patient rights or caregiver self-care in isolation.

Why Behavior and Communication Dominate the Exam

If you only had time to master two domains before test day, Behavior and Communication would be the obvious choice - together they represent roughly a third to nearly 40% of the entire exam. This weighting isn't arbitrary. Behavioral expressions like agitation, wandering, repetitive questioning, and resistance to care are the daily reality of dementia caregiving, and they're also where untrained caregivers make the most costly mistakes. NCBAC built the exam to heavily test whether a candidate can recognize the unmet need or environmental trigger behind a behavior, rather than simply reacting to the behavior itself.

Communication is inseparable from Behavior in practice - most behavioral interventions are communication interventions. Expect exam scenarios where you must choose the response that validates the person's reality rather than correcting or arguing with them, since this reflects the standard of care taught in accredited dementia-care training programs.

For a deeper look at how difficult candidates generally find these scenario-based questions compared to more fact-based domains, read How Hard Is the CAC Exam? Complete Difficulty Guide 2026. And if you want to understand exactly how the 664 threshold on the 300-900 scale is calculated, our dedicated breakdown at CAC Passing Score 2026: Exactly What You Need to Pass walks through it in detail.

The Smaller Domains: Still Worth Mastering

It's tempting to treat the bottom four domains - Health, Patient Rights, Safety, and Caregiver Needs - as afterthoughts because their combined weight is smaller than Behavior alone. That would be a mistake. Together, these four domains still account for a meaningful share of the 100 questions, and because they're more fact-based than scenario-based, they're often easier points to secure with focused review.

• Patient Rights (5-8%) tends to test clear-cut ethical principles - dignity, consent, and abuse reporting - that have unambiguous correct answers.
• Health (5-10%) often overlaps with basic monitoring skills already familiar to CNAs, LPNs, and RNs pursuing the certification.
• Safety (4-6%) covers concrete, memorizable protocols around fall prevention and wandering.
• Caregiver Needs (2-5%) is the lightest domain but shows up reliably enough that skipping it entirely is risky.

Because these domains reward straightforward memorization rather than nuanced judgment, they're ideal candidates for late-stage review using flashcards or a condensed reference. Our CAC Cheat Sheet 2026: One-Page Review of Must-Know Facts is built specifically to help you lock in these smaller domains in the final days before your test.

Question Format and What to Expect on Test Day

All eight domains are tested through a single 100-question, multiple-choice exam delivered in 2 hours 30 minutes. There is no separate section or timed block per domain - questions from all eight content areas are interspersed throughout the exam, so you need working knowledge across all of them rather than the ability to "cram and forget" one domain at a time.

NCBAC currently delivers the CAC exam through a browser-based remote-proctoring process that requires no software installation. To sit for the exam from home or another location, you'll need:

• A valid government-issued photo ID
• A working camera for proctor verification
• A reliable internet connection
• A supported device - computers and Chromebooks work, but phones and tablets are not supported

Scoring is reported on a scaled 300-900 range rather than a raw percentage, with a passing score of 664. This scaled approach accounts for minor variations in exam form difficulty, so don't try to reverse-engineer "how many questions you can miss" - focus instead on solid performance across all eight domains, weighted toward Behavior and Communication.

Mapping a Study Plan to the Domain Weights

Rather than studying domains in the order they're listed in the handbook, build your schedule around their exam weight. A domain-weighted study timeline over four weeks might look like this:

This kind of weighted, domain-first approach is far more effective than generic study techniques applied evenly across material. If you want a complete week-by-week prep plan built around this same logic, our CAC Study Guide 2026: How to Pass on Your First Attempt expands on each week in more depth. You can also reinforce each domain using realistic practice questions on our CAC practice test platform, which mirrors the multiple-choice format and timing you'll face on exam day.

Registration, Fees, and Eligibility Snapshot

Before you can sit for the exam and be tested on these eight domains, you need to meet NCBAC's eligibility requirements. The standard path requires:

• Being at least 18 years old
• At least 15 hours per week of paid or unpaid direct dementia-care experience for one full year (reduced to six months for CNAs, LPNs, or RNs)
• At least 25 hours of dementia-care training completed within the previous two years

An alternative route allows candidates 18 or older to qualify through participation in a Dementia Training/Apprenticeship Program instead of accumulating the standard experience hours. Full details on both pathways are covered in CAC Requirements 2026: Eligibility, Prerequisites & How to Qualify.

On the financial side, the exam fee is $175. Candidates who want structured preparation can add NCBAC's optional Caregiver Course for $500, bringing the total to $675, with course access lasting 90 days or until the exam is taken, whichever comes first. Once certified, renewal is required annually for $35 along with six continuing-education hours. A full cost comparison, including whether the optional course is worth adding, is available in CAC Certification Cost 2026: Complete Pricing Breakdown.

Once certified, employers across memory care units, assisted living communities, and home care agencies recognize the CAC credential as evidence of specialized dementia-care competency across all eight domains - not just general caregiving skills.
