- HHSC - not a testing vendor - determines the TX-MA written exam site and the passing grade.
- The combined permit application and exam fee is $25, nonrefundable, paid through the HHSC portal.
- Standard-route candidates who fail get one free retake if they meet the failure-notice deadline.
- A second failure means repeating the full 140-hour approved training program before testing again.
Understanding the TX-MA Passing Grade
Anyone searching for a specific "you need 75% to pass" number for the Texas Medication Aide Written Examination is going to be disappointed - and honestly, better off. The Texas Health and Human Services Commission (HHSC) does not publish a fixed universal percentage as public policy. What HHSC does publish, through 26 TAC Chapter 557, is that HHSC determines the written examination site and passing grade. That single sentence is the real answer to "what's the TX-MA passing score": it's whatever standard HHSC has set for that administration, not a number a prep site can guarantee.
That doesn't mean you're studying blind. It means your job is to master the required training curriculum thoroughly enough that wherever HHSC sets the bar, you clear it with room to spare. That's a different mindset than cramming toward a magic cutoff - and it's the mindset the TX-MA Study Guide 2026: How to Pass on Your First Attempt is built around.
Who Actually Sets the Passing Score
It helps to be precise about who runs what here, because the acronym "TX-MA" gets used loosely online. This article covers the standard Texas facility medication-aide permit and written examination administered under HHSC authority - not a medical-assistant credential, not the national MACE exam, and not a corrections-specific pathway. If you landed here researching one of those other programs, the facts below won't apply.
For the HHSC written exam, the agency sets:
- The passing grade for the written examination
- The examination site where you test
- The content basis: your approved training curriculum and clinical experience
Because HHSC - not a third-party certifying body - owns the passing standard, your best strategy is curriculum fidelity: know the same material your 140-hour program taught, cold, rather than chasing outside "exam secrets."
Key Takeaway
Treat your 140-hour approved training program as the actual answer key. HHSC bases the exam on that curriculum and your clinical experience, not on outside test banks.
What the Written Exam Is Really Testing
The written examination assesses your ability to support accurate, safe drug therapy using what you learned in your required training curriculum and clinical hours. That framing matters: this is not an abstract pharmacology test. It's a safety-and-process test built around the day-to-day judgment calls a medication aide makes in a Texas facility.
Your 140 hours of approved training break down as:
- 100 classroom hours
- 20 initial return-skills laboratory hours
- 10 clinical hours under a licensed nurse
- 10 further return-skills laboratory hours
Every one of those hours feeds into the pool of knowledge the written exam draws from.

Curriculum Topics That Drive the Passing Grade
Because HHSC bases the written exam on your required curriculum rather than a separately weighted blueprint, the smartest prep strategy is to treat every listed curriculum topic as fair game. Here are the clusters worth building study sessions around.
Medication Handling and Documentation
Covers preparation and administration of medications, control, accountability, storage and safeguarding, correct use of reference materials, and documentation practices - including how PRN medications must be recorded.
- Know the difference between administering and documenting a PRN dose
- Understand storage and safeguarding rules for controlled and non-controlled medications
- Practice reading reference materials the way your training program taught you to
Standards, Supervision, and Liability
Covers pharmaceutical, nursing, clinical-record, and facility certification standards, plus supervision and authority, and your personal responsibility and liability as a medication aide.
- Understand where your authority ends and a licensed nurse's begins
- Know what "supervision" means in a facility setting under Texas rules
- Be able to identify liability scenarios versus properly authorized actions
Practice Boundaries and Clinical Judgment
Covers permitted and prohibited practices, drug reactions and side effects, and the medication-aide rules that govern day-to-day conduct.
- Memorize which tasks are explicitly prohibited for medication aides
- Be ready to recognize and describe common drug reactions and side effects
- Apply medication-aide rules to short workplace scenarios, not just definitions

Scope-of-Practice Traps That Cost Points
A large share of missed points on medication-aide style written exams comes from scope-of-practice confusion, not raw pharmacology. Texas rules draw firm lines that show up repeatedly in scenario-based questions.
- PRN administration: a medication aide may administer and document nurse-authorized PRN medications, but decisions requiring independent clinical judgment remain outside a medication aide's authority.
- Injections: medication aides are prohibited from giving injections. Any question suggesting otherwise is testing whether you know this boundary.
- Dose calculation: calculating medication doses is likewise outside the scope of practice - a medication aide administers within already-determined, prescribed parameters, not by computing dosages independently.
These boundaries aren't arbitrary trivia - they reflect the actual legal limits of the permit under 26 TAC Chapter 557, and they're exactly the kind of judgment call the written exam is designed to check before HHSC issues a permit.
What Happens If You Don't Pass
Retake policy differs sharply by route, and mixing them up is a common and costly mistake.
| Situation | What Happens |
|---|---|
| Standard training-route applicant fails once | HHSC may grant one subsequent examination without an additional exam fee, upon request, if the retake meets the deadline stated in the failure notice |
| Standard training-route applicant fails a second time | Must complete another full approved training program before testing again |
| Nursing-graduate route applicant fails | Retaking the failed examination is not permitted under this route |
| Reciprocity route applicant fails | Retaking the failed examination is not permitted under this route |
Key Takeaway
Read your failure notice carefully - the retake deadline it states is binding. Missing it can push a standard-route candidate into repeating the entire 140-hour training program.
It's also worth noting that nursing-graduate and reciprocity applicants face additional requirements - including an open-book examination on top of the written examination - that don't apply to standard training-route candidates. Don't assume the standard route's one-retake safety net applies to those alternate pathways; it explicitly does not.

Fees Tied to Testing and Retesting
Money mechanics matter when you're planning a retake strategy. The combined permit application and examination fee is a nonrefundable $25, submitted through the HHSC online portal within 20 days after training enrollment, along with required education documents and completion of the fingerprint-based criminal-background process. Annual renewal after your initial 12-month permit costs $15.
Because the standard route's first retake is granted without an additional exam fee, your real financial risk isn't the exam fee itself - it's the cost and time of repeating training if you fail a second time. That's a strong argument for treating your first attempt as the one that counts.

A Focused Study Timeline
Generic study hacks don't mean much without mapping them to what the TX-MA written exam actually covers. Here's a compact way to sequence your final weeks before testing, built around the curriculum clusters above rather than a one-size-fits-all template.
Medication Handling and Documentation
- Drill preparation, administration, and storage/safeguarding rules
- Practice documenting PRN medications correctly
Standards, Supervision, and Liability
- Review facility, nursing, and clinical-record standards
- Work through scenarios distinguishing your authority from a nurse's
Practice Boundaries and Scope of Practice
- Memorize permitted vs. prohibited practices, including injections and dose calculation limits
- Review drug reactions and side effects from your training materials
Full Review and Scenario Practice
- Run timed practice questions modeled on all curriculum topics
- Re-check your failure-notice retake deadline procedure so you know it before you need it
Once you've built familiarity with the material, reinforce it with realistic scenario questions on our TX-MA practice test platform so exam-day format feels routine rather than unfamiliar.
