1.2 Official Source Control: Prometric, HHSC, and TAC

Two kinds of knowledge, two reliability levels

A Texas CNA candidate needs care knowledge (how to provide safe, respectful, infection-conscious resident care) and process knowledge (how training, testing, Registry placement, retakes, renewal, and conduct rules work). Care principles are stable for years. Process facts - fees, scheduling rules, remote-testing options, form names - change far more often. Because process facts change, source control is a study skill, not a formality.

For logistics, the controlling sources are the Prometric Texas Nurse Aide page and the current Texas Candidate Information Bulletin (CIB). HHSC contracts with Prometric for examination development, scoring, and reporting, so when you need the written test length, the Oral option, the Clinical Skills structure, current fees, identification rules, scheduling, or remote-proctoring language, check Prometric first - before trusting a blog, a forum post, or last year's class handout.

For the regulatory background, the controlling sources are Texas HHSC and the Texas Administrative Code (TAC), Title 26, Chapter 556 (Nurse Aides). These govern the 100-hour training requirement, Registry listing, resident rights, renewal, and the conduct that can produce a disqualifying finding. A study guide may summarize these, but you should always know where the summary came from and be ready to verify it.

Source control routine

What the controlled sources actually say today

Verified current figures: first-time fees are $125 for Written plus Clinical Skills and $135 for Oral plus Clinical Skills. Individual or retake fees are $35 Written only, $45 Oral only, and $90 Clinical Skills only. The written knowledge test is 60 multiple-choice questions in 90 minutes. Training under the Nurse Aide Training and Competency Evaluation Program (NATCEP) is 100 clock hours: 60 classroom and 40 supervised clinical.

Worked example of source control in action: a popular blog posts that the "Texas CNA written passing score is 80%." You are tempted to memorize 42, 45, or 48 correct answers as your target. The correct move is to stop. Prometric does not publish a single fixed Texas written passing-score percentage that this guide can confirm, and other states range from roughly 70% to 80%, so a borrowed number is a guess dressed as a fact. The safe study habit is to master the content outline and answer every item safely, not to chase an unverified cutoff.

Good source control also prevents wrong remote-testing assumptions. Current Prometric information says Written or Oral exams may be available through remote proctoring, while the Clinical Skills exam is site-based - it requires hands-on performance in an approved setting. A candidate who plans the entire certification "from home" has misread the rules and may waste a travel decision.

Separate official rules from local and classroom rules

Three layers of rules exist, and candidates routinely confuse them:

• State certification rules (Prometric + HHSC + TAC) - these control your credential.
• Training-program rules (your school's practice checklists, classroom finals, attendance) - these prepare you but do not place you on the Registry.
• Facility rules (uniform policy, parking, shift assignment, charting system) - these matter at one job site only.

A classroom final is not the state knowledge test. A facility's skills checklist is not the Prometric Clinical Skills test. Mixing these up leads candidates to assume they are "done" when they are not.

Treat official pages like medication labels: read the current version, not what someone remembers from last year. Before paying, scheduling, retesting, or making travel plans, confirm the bulletin, the Prometric Texas page, and your program's written instructions. Keep copies of confirmations, receipts, eligibility notices, and result reports in one place. That recordkeeping habit mirrors professional practice: CNAs rely on accurate information, follow current instructions, and ask the right authority - Prometric, HHSC, or the training program - when something is unclear.

How to spot a stale or unreliable source

Third-party study sites and forum posts are useful for orientation, but they age badly. Train yourself to flag warning signs before you trust a number. A page that gives no "last updated" date, cites no official source, lists a fee that ends in an odd amount no current bulletin shows, or states a precise Texas written passing-score percentage should be treated as unconfirmed until you check Prometric or HHSC. Screenshots circulated in study groups are especially risky because the original date is lost. When two sources disagree, the more recent official source wins, not the one that is more convenient or more encouraging.

A quick verification drill before any money or travel decision: open the current Prometric Texas Nurse Aide page and the linked Candidate Information Bulletin, confirm the fee for your exact route, confirm whether your knowledge test can be remote, and confirm the site requirement for Clinical Skills. Then check HHSC for anything touching the Registry or renewal, and check the Texas Administrative Code only when you need the underlying rule (for example, the 100-hour training split). This three-tier habit - Prometric for logistics, HHSC for Registry and renewal, TAC for rules - keeps you from absorbing a confident-sounding but outdated claim.

The same discipline protects residents later: a CNA who verifies the current order, the current label, and the current policy rather than "what we did last time" is exactly the professional this exam is built to certify.
