Practice the exact content PSI puts on your Colorado barbering exam. Mapped to the official topic breakdown below — no guessing, no generic Milady-style filler.
Direct from the Colorado Office of Barber and Cosmetology Licensure and the PSI candidate bulletin.
Your SGS dashboard tracks your score in each of these categories so you know exactly where to study.
The tools students use every night in the 30 days before their test.
Colorado uses the PSI exam, which requires 75% or higher to pass. Practicing at least 10% above that on SGS mock exams is the sweet spot students who pass on the first try hit.
Colorado requires 1500 training hours for barbering, along with completing the PSI exam (written + practical). Minimum age is 16.
Every SGS practice question is mapped to the same topic categories PSI uses: Scientific Concepts (Infection Control, Safety); Hair Cutting and Styling; Facial and Shaving Services; Chemical Services. Your progress dashboard shows which categories you're strong in and which need work before test day.

A huge trap for Colorado barbering candidates is underestimating the depth of knowledge required for Scientific Concepts (Infection Control, Safety). Many focus heavily on cutting and styling, assuming the safety stuff is just common sense. PSI's questions in this 30% category go beyond basic handwashing. They'll test your knowledge of bloodborne pathogens, proper disinfection levels for different tools, and the specific steps for handling accidental exposures. Don't just skim this section; truly understand the protocols and why they are in place.
