Practice the exact content PSI puts on your Tennessee barbering exam. Mapped to the official topic breakdown below — no guessing, no generic Milady-style filler.
Direct from the Tennessee Board of Cosmetology and Barber Examiners 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.
Tennessee 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.
Tennessee 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 common pitfall for Tennessee barbering candidates is underestimating the depth of knowledge required for the Scientific Concepts section, especially Infection Control. Many candidates focus heavily on the practical cutting and styling, but PSI's questions on disinfectants, sterilization levels, bloodborne pathogens, and client safety protocols can be very detailed. Don't just memorize definitions; understand *why* certain procedures are followed and *how* they prevent the spread of disease. Practice scenarios in your head: "What do I do if..." for every safety rule.
