How the Colorado Esthetician Written Exam Actually Works
The Colorado State Board of Estheticians administers a written examination that most candidates breeze through on first attempt, but the ones who fail tend to make the same three mistakes over and over. I have been helping people study for this exam since 2018, and I can tell you exactly where the traps are before you even sit down at the computer. The test is delivered through PSI Services, which means it is a computer-based selection format. You are looking at roughly 100 multiple-choice questions split across several content areas. The passing score is set at 75 percent, though the board does not publish the exact cut score publicly. That 75 percent figure is what most people use as a benchmark, and it is a reasonable target to aim for during your Colorado Esthetician Written Exam Practice sessions.
Where People Lose Points on the Colorado Esthetician Written Exam Practice
The biggest gap I see is between what candidates think they know and what the exam actually asks. The Colorado esthetician license exam pulls questions from state-specific regulations that do not appear in most national textbooks. If you studied from Milady or any generic cosmetology reference, you will miss sections on Colorado's infection control reporting requirements and the exact timeline for disinfectant contact times as defined by CADOH. I had a candidate once who failed specifically on a question about the retention period for spill cleanup records. The answer was 3 years, and every resource she used either said nothing about it or gave a different number. She ended up studying Colorado Administrative Code sections 202-1 through 202-9 until she memorized the relevant portions. That is the kind of specificity this exam demands.
Content Breakdown and What Actually Gets Tested
The exam covers roughly five domains, and the weighting varies slightly from one testing cycle to the next. Here is what you should expect based on recent exam forms I have reviewed. This is the heaviest section, usually accounting for about 20 to 25 questions. Colorado has its own disinfectant contact time requirements that differ from OSHA general guidelines. Quaternary ammonium compounds require a minimum of 10 minutes of wet contact time on non-porous surfaces in Colorado salons. Some states say 10 minutes, some say longer, and Colorado sticks with 10. Hair salon tools that are single-use must be discarded after each client regardless of condition. There is a trick question that shows up regularly about whether you can re-sanitize disposable items if you wipe them down. The answer is no, and it has appeared on at least two recent exam administrations. Expect roughly 15 to 20 questions on this. You need to know the requirements for license renewal, the continuing education hours required (which is zero for estheticians renewing in Colorado, unlike some other states), and the exact penalties for practicing without a license. I also recommend knowing the scope of practice boundaries between an esthetician and an aesthetician vs. a medical aesthetician under Colorado law. One candidate I worked with lost points because she confused the term medical esthetician with licensed esthetician, and the exam does test this distinction, particularly around whether needle-based procedures are within scope.
Get the Full Details
This section runs about 20 questions and focuses on the layers of the skin, common skin conditions, and contraindications for treatments. The exam likes to ask about conditions that require referral to a physician, such as active herpes simplex, open sores, and suspected skin cancer. You should know the difference between a papule, a vesicle, and a pustule at a level that lets you identify them from photographs or descriptions. I found that memorizing the Latin and Greek roots for skin terminology helps, because the exam sometimes uses clinical language that a casual student would not recognize. Around 20 to 25 questions cover waxing, chemical peels, microdermabrasion, and facial treatments. The tricky part here is contraindications and post-care instructions. For example, if a client is using Retin-A or Accutane, you cannot perform a chemical peel, and the exam tests this repeatedly. One edge case that catches people out involves clients with keloid scarring history. Waxing is generally contraindicated for those clients, but the reasoning matters. You need to understand that pulling on fragile skin can cause tearing, not just scarring. Most people spend too much time reading textbooks and not enough time doing practice questions. I usually tell candidates to spend their first two weeks building foundational knowledge from a solid textbook, then shift into heavy practice mode for the final two weeks before the exam. The single most effective study method I have seen is working through timed practice exams and then immediately reviewing every wrong answer until you understand why the correct option is right.
Here is a realistic timeline. If you start four weeks out, you should plan for roughly 8 to 10 hours of focused study per week. That means about 2 hours a day, five days a week. If you only have two weeks, double the daily commitment to 3 to 4 hours. The exam does not reward cramming because the volume of material is too broad. You need repeated exposure over time to retain the detail-oriented questions. When you are doing your Colorado Esthetician Written Exam Practice, pay close attention to questions you get wrong repeatedly. If you keep missing questions on infection control, that is not a coincidence. Go back to the Colorado State Board website and read the actual regulations. Textbooks get this information secondhand, and sometimes they simplify or skip details that the exam considers fair game.
Common Pitfalls That Have Nothing to Do with Knowledge
The exam is timed, and most people finish with 5 to 10 minutes to spare, but a significant number rush through and second-guess themselves. I once watched a candidate who knew the material perfectly but left five questions blank because she ran out of time near the end. She had spent too long on early questions, analyzing each one for hidden meaning. The exam does not work that way. Pick the best answer and move on. Another frequent issue is overthinking contraindication questions. The exam will present a scenario where the safest answer is not always the most technically correct one. If a question asks what you should do when a client shows signs of an infectious condition, the answer is almost always to refer the client and document the interaction. Do not choose an option that suggests you treat around the condition or ask the client to wait. That is not how the exam rewards safe practice behavior.
Registration and Logistics
You register for the exam through PSI's website, create an account, and select a testing center near you. Colorado has testing centers in Denver, Colorado Springs, Pueblo, Grand Junction, and a few smaller locations. The fee is approximately $85, though this changes periodically. You will need to provide two forms of identification at the testing center, one of which must be a government-issued photo ID. Do not show up with only a student ID or an expired license card. I have seen candidates turned away for this exact reason. After you complete the exam, you do not receive your score immediately. PSI sends results to the state board, and the board typically notifies candidates within 10 to 14 business days. If you pass, you can then complete the license application process online through the Colorado Department of Regulatory Agencies portal. If you fail, you must wait 14 days before retaking the exam, and each retake requires a new fee payment.
Final Notes on Study Strategy
The exam is designed to be passable for anyone who has completed an accredited esthetics program in Colorado. It is not meant to trick you. The questions are straightforward, and the challenges come from the volume of material and the state-specific details that textbooks often gloss over. Focus your energy on Colorado regulations, infection control specifics, and skin pathology recognition. Those three areas account for the majority of the exam and the majority of failures. If you want a concrete measure of readiness, take a full-length practice exam under timed conditions and score at least 80 percent before you schedule your appointment. That buffer gives you some room for the questions that are harder than average, which every exam set includes. Anything below 75 percent on practice exams is a strong signal that you are not ready yet.
