- MACE has 60 questions in two hours, but only 50 are scored across three domains.
- Medication Administration, Observation and Reporting makes up 60% of scored content.
- Credentia administers MACE via live online proctoring; NCSBN no longer owns the content.
- Eligibility rules vary by state - Colorado requires active CNA status, Utah requires 100 training hours.
What Is MACE Certification?
The Medication Aide Certification Examination, better known as MACE, is the credentialing exam that allows nursing assistants and other qualified caregivers to administer medications in long-term care and residential settings. If you're asking what is MACE certification in the first place, the short answer is: it's a state-authorized pathway that expands a CNA's scope of practice beyond basic personal care into supervised medication administration.
MACE is not a general nursing exam. It tests a narrow, practical skill set - reading medication orders, administering by approved routes, observing for reactions, documenting accurately, and knowing exactly when to escalate to a nurse. For a broader overview of the credential's history and purpose, see our companion pieces on MACE meaning and what MACE stands for.
Who Administers the MACE Exam
Today, MACE is administered by Credentia. Results are reported through the Credentia platform, and the exam itself is delivered via live online proctoring rather than in a physical test center. This matters practically: you'll need a stable internet connection, a private room, a government-issued ID, and a webcam-enabled device that meets Credentia's proctoring requirements.
While Credentia runs the testing mechanics, your actual eligibility, certification, and any registry placement is controlled by your state's nursing or health authority - not by Credentia and not by NCSBN. That distinction trips up a lot of first-time candidates who assume one national body controls everything from training to renewal.
Key Takeaway
Register through Credentia for the exam itself, but confirm training-program approval, fees, and renewal cycles with your state nursing board - these are two separate systems.
Eligibility and State Requirements
There is no single national eligibility standard for MACE. Each state nursing or health authority sets its own prerequisites, and they can differ significantly in training hours, prior certifications required, and renewal timelines.
Two examples illustrate the range:
- Colorado: Requires completion of an approved Medication Aide Training Program and active CNA status before you can sit for the exam.
- Utah: Requires 100 total training hours through an approved pathway, split into 60 didactic (classroom) hours and 40 practical (hands-on) hours.
Because these requirements vary so widely, it's worth checking your specific state program before enrolling in any training course. Generic national guides won't tell you whether your state requires active CNA status first - only your state authority's published requirements will.
| State Example | Prerequisite | Training Structure |
|---|---|---|
| Colorado | Active CNA status required | Approved Medication Aide Training Program |
| Utah | Approved pathway completion | 100 hours total (60 didactic + 40 practical) |
Exam Format and Delivery
The English-language MACE exam consists of 60 multiple-choice questions, and candidates are given two hours to complete it. Here's a detail many candidates miss: while you'll answer 60 questions, the official content outline only scores 50 of them across the three domains. The remaining questions function as unscored pretest items, a common practice in credentialing exams that lets the exam owner evaluate new items without affecting your score.
Because you can't tell which items are scored and which aren't, the practical strategy is simple: treat every question as if it counts. There's no way to game which ones are "safe" to skip.
If you're trying to gauge how demanding this format actually is compared to other credentialing exams, our detailed breakdown in How Hard Is the MACE Exam? Complete Difficulty Guide 2026 walks through the format-related challenges in more depth, and MACE Pass Rate 2026: What the Data Shows covers what's publicly known about outcomes.
The Three MACE Domains
The current national content outline organizes MACE around three domains, and understanding their relative weight is probably the single most useful thing you can do before you start studying. For a full domain-by-domain breakdown, see MACE Exam Domains 2026: Complete Guide to All 3 Content Areas.
Domain 1: Authorized Duties (16%)
Covers the legal and procedural boundaries of what a certified medication aide can and cannot do - including scope-of-practice limits, delegation rules, and when a task must be referred to a licensed nurse.
- Know which routes and situations fall outside your authorized duties
- Understand delegation and supervision requirements
Domain 2: Medication Administration, Observation and Reporting (60%)
This is the dominant domain, worth well over half of all scored items. It covers the "Five Rights" of medication administration, proper administration technique by route, observing residents for adverse reactions, and documenting and reporting findings accurately.
- Master administration steps for oral, topical, and other authorized routes
- Recognize signs of adverse drug reactions and know reporting protocol
- Practice accurate documentation language and timing
Domain 3: Medication Concepts and Measurements (24%)
Focuses on pharmacology basics relevant to a medication aide's role - dosage calculations, measurement conversions, medication classifications, and storage/handling requirements.
- Practice basic dosage and measurement conversions
- Learn common medication classifications and their general purposes
For deep-dive, item-level study guides on each area, see MACE Domain 1: Authorized Duties (16%) - Complete Study Guide 2026, MACE Domain 2: Medication Administration, Observation and Reporting (60%) - Complete Study Guide 2026, and MACE Domain 3: Medication Concepts and Measurements (24%) - Complete Study Guide 2026.
Building a Domain-Weighted Study Schedule
Since Domain 2 alone accounts for 60% of scored questions, your study time should not be split evenly across the three domains. A weighted approach that mirrors the exam blueprint makes far better use of limited prep time than a generic weekly template.
Domain 2 Foundations
- Administration routes and the Five Rights
- Observation and adverse-reaction recognition
Domain 2 Continued + Domain 3
- Documentation and reporting language
- Dosage calculations and measurement conversions
Domain 1 + Integration
- Authorized duties and delegation boundaries
- Mixed practice across all three domains
Full Simulation
- Timed 60-question practice runs
- Review weak areas, focus final review on Domain 2
Notice that two of the four weeks stay anchored on Domain 2 specifically - that's intentional, not generic sequencing. For a complete lesson-by-lesson version of this plan, see MACE Study Guide 2026: How to Pass on Your First Attempt. You can also run full-length timed simulations on our MACE practice test platform to get comfortable with the two-hour, 60-question pacing before exam day.
Who Hires Certified Medication Aides
MACE-certified aides typically work in skilled nursing facilities, assisted living communities, and residential care settings where licensed nursing staff delegate medication administration under state-approved supervision models. Employers value the credential because it lets facilities extend medication coverage without adding nurse headcount for every shift.

Cost is another practical factor - training programs, state fees, and the exam itself all carry separate costs depending on your state pathway. Our full breakdown in MACE Certification Cost 2026: Complete Pricing Breakdown walks through what to budget for before you enroll in a training program like the ones described in MACE Training.
After You Pass: Renewal and Registry
Passing the exam is not the final step. Because certification and renewal are administered by the applicable state authority - not by Credentia - your ongoing status, continuing education requirements, and any registry listing depend entirely on your state's rules. Some states tie renewal to your CNA certification cycle; others run MACE renewal independently.
Before you sit for the exam, it's worth knowing exactly what maintaining the credential will require afterward, since lapses can mean re-testing or repeating training hours. If you haven't already, review the general overview in What Is MACE? and What Is A MACE? to make sure you understand the full lifecycle, not just the exam day itself.
Once you feel ready to test your knowledge under realistic time constraints, working through practice questions modeled on the actual domain weighting is one of the most reliable ways to confirm readiness. Our guide to Best MACE Practice Questions 2026: What to Expect on the Exam explains how question style on MACE differs from typical multiple-choice nursing exams, and you can start practicing directly on the MACE Exam Prep practice site whenever you're ready.
