Exam Format at a Glance
Before diving into content, lock in the mechanics. The Oklahoma Certified Medication Aide (CMA) Basic Written Examination - assessment 8606/6A - is delivered through the Oklahoma CareerTech Testing Center's Health and Professional Certification Project at approved test sites. The operational testing table effective July 1, 2025 (edited January 7, 2026) confirms the current specification: 65 multiple-choice questions, a two-hour time limit, and a 70% passing score. This matches the study guide revised January 1, 2017, which is the version currently linked for candidates. If you see a conflicting 70-question figure referenced elsewhere, treat the 65-question specification above as the operative one.
Delivery is computer-based at a proctored site - not an at-home exam. Testing is conducted in English and is closed-book: oral readers, translated exams, and calculators are not permitted. Proctors provide scratch paper, and you must return it before leaving. For a deeper walkthrough of how the exam is structured and administered, see the OK-CMA Study Guide 2026: How to Pass on Your First Attempt.
The Six Domains, Ranked by Weight
The written exam outline is built around six content areas. Knowing the official question counts - not just the rounded percentages - helps you allocate study time honestly instead of spreading effort evenly across topics that don't carry equal weight.
| Domain | Weight | Approx. Questions |
|---|---|---|
| Administer Medication | 41% | 27 |
| Comply with Legal and Ethical Guidelines | 18% | 9 |
| Observe, Report, and Document Client Status | 14% | 12 |
| Apply Knowledge of Body Systems and Common Diseases | 11% | 7 |
| Apply Principles of Safety | 8% | 5 |
| Apply Knowledge of Measurement Systems | 8% | 5 |
Domain 1: Administer Medication (41%)
This is nearly half your exam. It covers routes of administration, dosage calculation basics, medication classifications, storage, and the step-by-step process of preparing and giving medications safely.
- Know common routes (oral, topical, sublingual, rectal, and others covered in your training) and when each is used.
- Understand how PRN medications are administered under Oklahoma's licensed-nurse assessment or authorization requirements - this is not a blanket prohibition, but a supervised process.
- Be comfortable distinguishing basic CMA authority from advanced pathways like insulin/glucose monitoring, feeding-tube administration, and inhaler/nebulizer use, which fall outside the basic assessment.
Domain 3: Comply with Legal and Ethical Guidelines (18%)
The second-largest domain tests your understanding of scope of practice, resident rights, confidentiality, informed consent, and reporting obligations under Oklahoma nurse aide and CMA regulations.
- Review what qualifying nurse-aide certification means and why it must stay active alongside your CMA credential.
- Study the boundaries between what a CMA can do independently versus what requires a licensed nurse's involvement.
For a full breakdown of every domain with sample topics and study weighting logic, see the OK-CMA Exam Domains 2026: Complete Guide to All 6 Content Areas. If you're still deciding how demanding this exam really is relative to your background, the How Hard Is the OK-CMA Exam? Complete Difficulty Guide 2026 breaks down what makes each domain challenging.
Eligibility & Registration Snapshot
You cannot sit for the basic CMA written assessment without meeting the Oklahoma State Department of Health's eligibility criteria first. Here's the condensed version:
- Be at least 18 years old with a high school diploma or GED and functional English ability.
- Hold an active, qualifying Oklahoma long-term-care, home-health, or ICF/IID nurse-aide certification in good standing.
- Have at least six months of nurse-aide experience.
- Complete approved CMA training: a minimum of 40 total hours, including at least 16 hours of supervised practical training.
- Pass post-training competency verification - administering medication to 20 consecutive individuals with 100% accuracy. This happens in addition to your course clinical training; it is not a separate CareerTech skills-test station.
Key Takeaway
If your nurse-aide certification lapses at any point, your CMA eligibility and renewal are affected too - the two credentials are linked, not independent.
For the full eligibility checklist with documentation details, visit OK-CMA Requirements 2026: Eligibility, Prerequisites & How to Qualify. If you fail the written exam, remember you get three attempts as a newly trained candidate, with at least three days required between attempts; a third failure means repeating approved training before you can test again.
The Seven Rights of Medication Administration
The Oklahoma outline builds much of Domain 1 around the seven rights framework. Memorize these cold - they show up across multiple question stems, not just in one section:
- Right Resident - verifying identity before every administration.
- Right Medication - matching the drug to the order exactly.
- Right Dose - confirming the correct amount, tied into measurement-system knowledge.
- Right Route - oral, topical, or another approved method for that medication.
- Right Time - administering within the scheduled window.
- Right Documentation - recording administration accurately and promptly.
- Right to Refuse - respecting a resident's right to decline and documenting/reporting it appropriately.
Scope of Practice: What Basic CMA Covers
A recurring theme across Domains 1 and 3 is understanding exactly where basic CMA authority ends. This exam covers the basic Certified Medication Aide assessment (8606/6A) - not advanced medication-aide endorsements. That distinction matters for several question types:
- PRN medications: Administered through Oklahoma's licensed-nurse assessment or authorization process - know the workflow, not a prohibition.
- Insulin and glucose monitoring: Falls under advanced pathways beyond basic CMA scope.
- Feeding tubes: A separate advanced endorsement, not part of the basic exam's authority.
- Inhalers and nebulizers: Also outside basic CMA scope and covered under advanced training.
Confusing basic-scope questions with advanced-endorsement scenarios is a common way candidates lose points on legal/ethical items. If you want a plain-language explanation of what the credential actually authorizes day to day, start with What Is OK-CMA? and What Is OK-CMA Certification? for the foundational framing, or OK-CMA Certification for the credential overview.
Renewal & Continuing Education Quick Facts
Passing the exam is the milestone everyone studies for, but the credential requires upkeep. Keep these renewal facts on your cheat sheet too:
- CMA renewal happens annually.
- The renewal fee is $10.
- You need eight hours of approved continuing education per 12-month period - except your first certification year, which is exempt.
- Your underlying qualifying nurse-aide certification must remain active for your CMA certification to stay valid.
These figures come directly from Oklahoma's Chapter 677 regulations governing training, competency, scope, renewal, fees, and continuing education. For a complete cost picture across training, testing, and renewal, see OK-CMA Certification Cost 2026: Complete Pricing Breakdown.
One-Week Final Review Timeline
In the final week before your test date, resist the urge to study everything equally. Allocate time proportional to domain weight, front-loading Administer Medication and Legal and Ethical Guidelines since together they account for well over half the exam.
Administer Medication (41%)
- Drill the seven rights against scenario questions
- Review routes, classifications, and PRN authorization steps
- Separate basic-scope tasks from advanced-endorsement tasks
Legal and Ethical Guidelines (18%)
- Review resident rights, confidentiality, and reporting duties
- Confirm you understand qualifying nurse-aide certification requirements
Observe, Report, and Document (14%)
- Practice documentation-format questions
- Review what changes in client status must be escalated
Body Systems, Safety, and Measurement (11% + 8% + 8%)
- Review common diseases tied to medication classes
- Refresh measurement conversions and safety principles
Full-Length Practice and Review
- Take timed practice sets across all six domains
- Revisit only the domains where you're missing questions
This weighted approach - not a generic even split - is the core methodology behind the OK-CMA Study Guide 2026. If you want to benchmark your readiness before test day, run through timed questions on the OK-CMA practice test platform to simulate the two-hour, 65-question format.
Test-Day Rules Checklist
A surprising number of candidates lose points to avoidable procedural mistakes rather than content gaps. Confirm these before you arrive at your approved test site:
- Testing is proctored and computer-based at an approved location - you cannot test remotely or from home.
- The exam is administered in English only; oral readers and translated versions are not available.
- Calculators are prohibited - measurement and dosage questions must be worked manually.
- Scratch paper is proctor-supplied and must be returned before you leave.
- Bring the identification and documentation your test site requires to confirm your active nurse-aide certification and eligibility.

Why This Cheat Sheet Matters for Your Career Plans
Employers hiring for medication aide roles in Oklahoma long-term-care, home-health, and ICF/IID settings expect candidates who already hold active nurse-aide certification and have completed approved CMA training before they ever discuss job offers. Having this credential opens medication-related duties that a standard nurse aide role does not include.
