6.3 Final Review & Exam-Day Strategy
Key Takeaways
- The Texas written exam is computer-based at PSI: 100 scored multiple-choice questions plus 10 unscored pretest items, with 130 minutes total (120 min for the scored items plus 10 min for the pretest items).
- You must score 70% or higher on BOTH the written and the practical exam to be licensed.
- High-yield review spans sciences/infection control, hair, chemical services (pH and patch tests), skin, nails, and Texas law.
- Bring valid government photo ID matching your registration; arrive ~30 minutes early; pace at roughly one minute per question and flag-and-return.
6.3 Final Review & Exam-Day Strategy
The Texas cosmetology operator licensing exam has two parts: a written (theory) exam and a practical (skills) exam. The written exam is computer-based and administered by PSI. It contains 100 scored multiple-choice questions plus 10 unscored pretest questions used to develop future items, and you receive 130 minutes total — 120 minutes for the 100 scored items plus 10 minutes for the 10 pretest items. You must score 70% or higher on both the written and the practical exam to qualify for licensure — passing one does not carry the other.
High-yield cram by domain
Use this as a last-night sweep. Each line is a frequently tested anchor.
| Domain | Must-know anchors |
|---|---|
| Infection control / TX law | Clean then disinfect; EPA-registered hospital-grade disinfectant; single-use vs multi-use; TDLR + PSI; 2-yr renewal; 4 CE hours |
| Sciences | Bacteria (cocci, bacilli, spirilla), pathogenic vs non-pathogenic; pH scale 0-14, 7 is neutral; hydrogen vs disulfide bonds |
| Hair | Anagen/catagen/telogen growth cycle; cortex holds color/curl; cuticle is outer layer; ~90% of scalp hair is in anagen |
| Chemical | Cold waves are alkaline (thio breaks disulfide bonds); neutralizer is an oxidizer that rebonds; perform a patch/predisposition test 24-48 hrs before tint |
| Skin / esthetics | Epidermis layers (stratum corneum outermost); UVA ages, UVB burns; perform skin analysis before facials |
| Nails | Matrix produces the nail plate; never service infected/inflamed nails; MMA monomer is prohibited |
Most-missed traps
- "Disinfect" vs "sterilize": salons disinfect non-porous tools; they do not sterilize. Choosing autoclave/sterilize is usually wrong.
- pH math: the pH scale is logarithmic — each whole number is a 10x change. A pH of 9 is 100x more alkaline than a pH of 7.
- Patch test timing: a predisposition (patch) test for aniline derivative tint is done 24-48 hours before the service, not the same day.
- Thio vs neutralizer: the waving lotion breaks disulfide bonds; the neutralizer oxidizes/reforms them — do not reverse these.
- Texas specifics: TDLR (not a "board"), 2-year renewal, $50 on-time fee, 4 CE hours (or 2 for 15+ year holders).
PSI exam-day logistics
Arrive at the PSI test center about 30 minutes early. Bring a valid, current government-issued photo ID whose name exactly matches your exam registration (a mismatch can forfeit your seat and fee). Personal items — phones, notes, smartwatches — are not allowed at the workstation and go in a locker; bringing prohibited materials can void your results. The exam is closed-book; an on-screen calculator and tutorial are provided. You will see your pass/fail result at the workstation when you finish.
The practical exam
The Texas practical exam is a hands-on skills test where you perform required services on a mannequin or model and bring your own supplied kit. You are scored on sanitation/infection control, correct procedure, and safety — examiners watch whether you disinfect implements, drape the client, and follow sequence. The single most common practical failure is sanitation lapses, not technique: forgetting to disinfect a tool, double-dipping, or contaminating a clean implement. Treat every step as if an inspector is watching, label your disinfected vs. soiled containers, and follow the announced timing for each task.
You must reach 70% here independently of the written score.
Two-week study plan
| When | Focus |
|---|---|
| 14-10 days out | Sciences + infection control; build flashcards for terms (anagen, cortex, pH) |
| 9-5 days out | Hair, chemical services (pH, bonds, patch test), Texas law (TDLR, CE, fees) |
| 4-2 days out | Skin, nails, full-length timed practice tests at 70%+ |
| Day before | Light review of missed items; prep ID + directions; sleep |
Scoring and what to bring
The written exam is scored on the 100 operational questions only — the ~10 unscored pretest items do not count, so do not panic over an oddly worded question. Your score report prints at the test center and shows pass/fail; failed candidates receive a diagnostic by content area to guide a retake. You may retake after re-registering and paying the exam fee again; there is a short waiting period between attempts. Bring exactly two things you control: a valid photo ID and your confirmation. Leave everything else in the car or a locker.
Pacing strategy
With ~100 scored questions in ~120 minutes you have a little over one minute per question. Make a first pass answering everything you know quickly, flag anything that takes more than ~90 seconds, and return to flagged items at the end. Never leave a blank — there is no penalty for guessing, so eliminate two wrong options and choose the best remaining answer. Read the full stem; watch for qualifiers like "EXCEPT," "NOT," and "FIRST/BEST." Trust your first instinct unless you find concrete evidence to change it.
Worked example
A question asks: "All of the following are single-use items EXCEPT..." with options emery board, neck strip, metal shears, and cotton ball. The word EXCEPT flips the logic: three answers are single-use and you must pick the one that is not — metal shears, a multi-use tool that is cleaned and disinfected. Misreading EXCEPT is one of the most common avoidable errors on the Texas written exam.
