Pass your cosmetology state board written exam on the first try. 1,000+ questions covering hair, skin, nails, sanitation, and state licensing regulations.
The cosmetology state board written exam is the final step before receiving your cosmetology license. After completing your state-required hours of cosmetology school (typically 1,000-1,500 hours), you must pass both a written knowledge exam and a practical skills examination.
Most states use the NIC (National Interstate Council of State Boards of Cosmetology) written exam, which consists of 100 scored questions plus 10 unscored pretest questions. The exam covers the full scope of cosmetology theory including hair science, chemical services, skin care, nail care, sanitation protocols, and state licensing regulations.
PrepTestAI covers all NIC exam topics with scenario-based questions that mirror the format and difficulty of the actual state board written exam. Our AI tutor explains the science behind every concept so you truly understand the material — not just memorize answers.

The National Interstate Council of State Boards of Cosmetology develops the standardized written exam used by most states. Some states develop their own exam. Check your state board of cosmetology to confirm which exam you will take.

Understanding the difference between sterilization, disinfection, and sanitization — and when each is required — is critical. Hair color theory and chemical services are also heavily tested.
This varies by state. Some states schedule both the written and practical exams on the same day, while others allow or require them to be taken on separate days. Check your state board for scheduling requirements.
