How to Pass Your Texas Cosmetology Licensing Exam (TDLR Written and Practical)

To pass your Texas cosmetology licensing exam, you need a score of 70 or higher on both the written exam and the practical exam. The written test is administered by PSI after you complete 900 of your 1,000 required training hours. The practical exam tests hands-on skills after you finish your full program and pass your theory exam.

With focused preparation and consistent practice during school, most students pass on their first attempt.

  • Exam fees: $25 permit, $55 theory, $76 practical, $50 license

Understanding the Two Exams

Texas splits the cosmetology licensing exam into two parts:

Written Exam (Theory)

  • Computer-based, administered at PSI testing centers across Texas
  • Covers: sanitation and safety, hair and scalp science, chemistry of products, color theory, Texas cosmetology laws and regulations
  • You can schedule this exam after completing 900 hours of your program
  • Results are typically available within 24 to 48 hours

Practical Exam

  • Hands-on, in-person exam at a PSI testing facility
  • You bring your own mannequin, tools, and supplies
  • Covers: haircutting, chemical waving (perm), hair coloring, and sanitation procedures
  • Available after you finish all 1,000 hours AND pass the written exam
  • Examiners watch you perform each service and grade technique, safety, and timing

What Is on the Written Exam?

The written exam covers five main topic areas:

  • Sanitation, bacteriology, and infection control (heavily weighted) — Disinfection procedures, types of pathogens, proper tool storage. This is the most-tested topic on the exam.
  • Hair and scalp science — Hair structure (cortex, medulla, cuticle), growth cycles, scalp conditions. Understanding porosity and elasticity.
  • Chemistry — pH levels, oxidation, reduction, how chemical services work. Color chemistry (permanent, semi-permanent, lightener).
  • Services and procedures — Cutting techniques, chemical texturizing, coloring procedures. Safety precautions for each service type.
  • Texas laws and regulations — TDLR rules, salon licensing requirements, sanitation regulations. Client consultation requirements.

Study Tips for the Written Exam

Start early. Do not cram the week before. Review theory notes consistently throughout your program. By the time you reach 900 hours, the material should feel like review, not new information.

Use practice tests. PSI publishes candidate information bulletins that outline exactly what is tested.

Practice exams are available online and through your school. Take at least 5 full-length practice tests before your exam date.

Focus on sanitation. This is the single most tested topic. Know the difference between cleaning, disinfecting, and sterilizing. Know which disinfectants are required for different tools. Know bloodborne pathogen protocols. If you know sanitation cold, you are halfway to passing.

Study Texas-specific rules. The exam includes questions about TDLR regulations that are specific to Texas.

Your program curriculum covers these, but review them separately to make sure you can answer regulation-based questions.

What Happens During the Practical Exam

The practical exam is structured. You perform specific services in a set order while an examiner observes.

Here is a typical exam flow:

  • Setup and sanitation check — Your workstation must be organized with all tools properly disinfected and displayed
  • Haircutting section — Perform a designated haircut on your mannequin (specific cuts are assigned)
  • Chemical service section — Demonstrate a perm wrap or chemical application
  • Hair coloring section — Apply foils to a designated section of the mannequin
  • Sanitation throughout — You are graded on maintaining sanitation at every step (sanitizing hands, disinfecting tools between services, proper disposal of chemicals)

Time management matters. You have a set amount of time for the entire exam. Practice your services with a timer during school so you can complete each section confidently without rushing.

Practical Exam Tips

Practice the exact procedures. The practical exam tests specific techniques in a specific order. Your school curriculum is designed to prepare you for exactly what the exam requires. Do not improvise.

Sanitation is your safety net. Even if your haircut is not perfect, strong sanitation protocol can keep your score above 70. Examiners deduct points for missed sanitation steps. Sanitize your hands before and after every service. Disinfect tools visibly and correctly.

Bring everything on the supply list. PSI provides a detailed list of what to bring. Missing supplies can prevent you from completing a section. Pack your kit the night before, check it twice, and bring backups of key items (extra clips, cape, neck strip dispenser).

Stay calm and methodical. The practical exam is not about speed. It is about demonstrating competency.

Move through each section steadily, narrate your steps mentally, and do not skip steps to save time.

How WEI Prepares You

At William Edge Institute, the entire 1,000-hour curriculum is structured with the licensing exam in mind.

Students practice the exact cutting techniques, chemical services, and sanitation protocols that appear on the practical exam. By the time you reach 900 hours and sit for the written exam, you have already spent months reinforcing the material through hands-on application.

WEI instructors know what the examiners look for because they have prepared hundreds of students for these exams. That focused preparation is one of the biggest advantages of attending a structured program versus trying to study independently.

What If You Do Not Pass?

If you do not pass on the first attempt, you can retake the exam. There is a waiting period and a retake fee, but it is not the end of the road. Review the areas where you lost points, practice those specific techniques, and schedule a retake.

Most students who attend every class, practice consistently, and take practice tests pass on their first attempt. The exam is designed to confirm that you have the skills to serve clients safely, not to trick you.
