About the cosmetology state board written exam

The cosmetology written (theory) exam is a timed multiple-choice test covering scientific concepts — infection control, anatomy and physiology, chemistry — and service procedures for hair, skin, and nails. Most states test 100–120 questions in 90–120 minutes with a pass mark around 70–75%; NIC-based exams use 110 questions in 90 minutes. Provider, format, and state-law coverage vary by state, so pick your state above and the mock exam follows its published blueprint.
