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.
Nevada 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.
Nevada requires 1500 training hours for barbering, along with completing the PSI exam (written + practical). Minimum age is 17.
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 frequent pitfall for Nevada barbering candidates is underestimating the depth required for the Scientific Concepts section. Because it's 30% of the exam, it's not enough to just memorize definitions. You need to understand the *why* behind infection control, the difference between disinfectants, and how to apply safety procedures in various scenarios. Don't just read about cross-contamination; visualize it and know the precise steps to prevent it. Many candidates focus heavily on the practical cutting skills, which are crucial, but neglect the theoretical underpinnings that keep clients safe and healthy. Really dig into the safety data sheets (SDS) information and proper ventilation for chemical services as well.
