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.
Iowa 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.
Iowa requires 2100 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 big pitfall for Iowa candidates is getting complacent with Infection Control within the Scientific Concepts section. Because it’s such a core part of your training from day one, many assume they’ve got it down. However, the exam often presents tricky scenarios or asks for specific details on disinfectant types, contact times, or proper disposal methods that can trip you up if you haven't reviewed them recently. Don't just know the basics; review the specific protocols for various tools and surfaces, and understand the difference between cleaning, disinfecting, and sterilizing. Treat it like it's brand new information, not something you already "know."
