- The MACE has 60 questions, two hours, but only 50 are scored across three domains.
- Medication Administration, Observation and Reporting is worth 60% of scored items - study it first.
- Credentia administers the exam through live online proctoring; no study aids are allowed during testing.
- Eligibility rules differ by state - Colorado and Utah require different training hour totals.
What This Cheat Sheet Covers
This is a one-page reference for candidates who already know the basics and just need the exact numbers, domain weights, and rules confirmed before test day. If you haven't started studying yet, the MACE Study Guide 2026: How to Pass on Your First Attempt walks through a full preparation plan.

Everything below is drawn directly from the current official content outline and administration rules - no filler, no guesses.
Who Runs the MACE and Who Sets Your Eligibility
The Medication Aide Certification Examination is currently administered by Credentia. This matters because it changes who you contact for registration, scheduling, and results. NCSBN has stated it no longer develops or owns MACE content, so any older study material referencing NCSBN as the exam owner is outdated for 2026 candidates.
Credentia handles the exam delivery and score reporting, but it does not decide whether you are eligible to sit for the exam or whether you can work as a certified medication aide afterward. That authority sits with your state nursing or health authority. States set their own training program approval standards, prerequisite certifications (such as active CNA status), and registry or licensing procedures. This two-layer structure - Credentia for the exam, the state for eligibility and licensure - is the single most misunderstood part of the process. For the full breakdown of what your state may require before you can even register, see MACE Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Exam Format at a Glance
The English-language MACE consists of 60 multiple-choice questions with a total time allowance of two hours. Of those 60 questions, the official content outline allocates 50 as scored items distributed across the three content domains - the remaining questions function as unscored items but are not distinguishable from scored ones during the test.
- Question type: Multiple-choice only
- Total questions delivered: 60
- Scored questions: 50 (across 3 domains)
- Time allowed: 2 hours
- Delivery method: Live online proctoring
- Results platform: Credentia
- Study aids during testing: Prohibited
Because the exam is proctored live online rather than at a physical test center, environment setup counts as much as content knowledge. If you're still unsure how difficult the format actually is compared to other certification exams, How Hard Is the MACE Exam? Complete Difficulty Guide 2026 breaks that down in detail.

The Three Domains, Ranked by Weight
Every scored question on the MACE falls into one of three domains from the national content outline. Knowing the weight of each domain tells you exactly where to put your limited study hours.
Domain 2: Medication Administration, Observation and Reporting (60%)
This domain carries more than half the scored exam and covers the practical core of the medication aide role: administering medications by approved routes, observing residents for expected and adverse effects, and documenting and reporting findings correctly. Expect scenario-based questions describing a resident situation and asking what action or report is appropriate.
- Correct administration technique for oral, topical, and other approved routes
- Recognizing signs of adverse reactions or side effects
- Proper documentation and chain-of-reporting procedures
- When to withhold a dose and escalate to a nurse
Domain 3: Medication Concepts and Measurements (24%)
This domain tests the math and pharmacology fundamentals that support safe administration: dosage calculations, measurement conversions, and basic medication classifications. Errors here are usually calculation mistakes made under time pressure rather than knowledge gaps.
- Metric and household measurement conversions
- Basic dosage calculation problems
- Common medication classifications and their general purposes
- Reading medication labels and administration records accurately
Domain 1: Authorized Duties (16%)
The smallest domain by weight, but not one to skip - it defines the legal and procedural boundaries of the medication aide role: what you are authorized to do, what requires a licensed nurse, and how those limits vary by care setting.
- Scope-of-practice boundaries for medication aides
- Situations that must be referred to a supervising nurse
- Setting-specific authorized duties
For a deeper walkthrough of sample question styles inside each domain, the MACE Exam Domains 2026: Complete Guide to All 3 Content Areas covers each area with more granularity than a one-page cheat sheet can.
Key Takeaway
Since Domain 2 alone accounts for 60% of scored questions, spend the majority of your review time on medication administration, observation, and reporting scenarios rather than splitting time evenly across all three domains.

State Eligibility Snapshot
Because state authorities - not Credentia - control who can sit for the MACE, prerequisite requirements vary widely. Two examples illustrate how different the paths can be:
- Colorado: Requires completion of an approved Medication Aide Training Program plus active CNA status before you can register.
- Utah: Its approved pathway requires 100 total training hours, split into 60 didactic hours and 40 practical hours.
These are just two examples - your state's program approval list, hour requirements, and prerequisite certifications may look completely different. Before you invest time or money into a training program, confirm your specific state's rules through the MACE Requirements 2026 guide, and check what registration actually costs in your state via MACE Certification Cost 2026: Complete Pricing Breakdown.
Domain-Priority Review Plan
Rather than a generic weekly template, structure your final review around domain weight so your remaining hours match the exam's actual scoring emphasis. This sequence assumes you've already completed your state-approved training program and are in the final stretch before scheduling.
Domain 2 - Medication Administration, Observation and Reporting
- Drill administration-route scenarios until the correct action is automatic
- Practice identifying adverse reactions from resident descriptions
- Review documentation and nurse-escalation procedures
Domain 3 - Medication Concepts and Measurements
- Re-practice metric and household conversions until calculation speed improves
- Work timed dosage-calculation problems, since the exam has a strict two-hour limit
- Review common medication classifications
Domain 1 - Authorized Duties
- Review scope-of-practice boundaries for your specific care setting
- Study situations requiring nurse referral
- Run full-length practice sessions mixing all three domains at their real weightings
This order isn't arbitrary - it front-loads the domain worth 60% of your score, then moves to the second-heaviest domain, and finishes with the smallest domain so it's fresh going into test day. For a full library of practice questions organized this same way, use the MACE practice test platform.
Test Day Rules You Cannot Break
Because the MACE is delivered through live online proctoring rather than in a physical test center, several rules apply that don't exist on paper-based exams:
- No study aids of any kind are permitted during the exam session - this includes notes, reference sheets, or outside materials.
- Your testing environment must meet the proctor's requirements before the session can begin, so treat setup as part of your preparation, not an afterthought.
- Results are reported through the Credentia platform, not through your training program or your state's website directly.
- Because the exam is timed at two hours for 60 questions, pacing matters - spend disproportionate time on Domain 2 items since they make up 60% of your score, but don't let any single question consume minutes you'll need later.
If any of these format details make the exam feel more intimidating than it needs to be, the MACE difficulty guide puts the format in perspective against what candidates actually report experiencing.
Where This Certification Leads
A medication aide certification is typically pursued by CNAs and other direct-care staff looking to expand their scope of practice within long-term care, assisted living, and similar settings - subject to what each state's authority authorizes. Employers hiring for these roles are generally looking for candidates who hold both an active CNA credential and a valid medication aide certification registered with the state.
