Pass the California Esthetician State Board Exam on Your First Try

Introduction

The California esthetician written exam is administered by PSI on behalf of the California Board of Barbering and Cosmetology (BBC). The exam consists of 75 scored questions plus 10 unscored pretest items and must be completed in 90 minutes. A score of 70% or higher is required to pass. As of January 1, 2022, the practical exam is no longer required — the written exam is the only requirement for licensure. To qualify, you must complete 600 hours of training at a BBC-approved esthetics school. Under SB 803 (effective January 1, 2022), California expanded the esthetician scope to include lash and brow lamination/perming and dermaplaning. The exam covers infection control and safety (32%), skin analysis and client consultation (20%), skin care services (25%), hair removal (8%), and California BBC laws (15%).

Exam overview

The California esthetician written exam is a computer-based, closed-book multiple-choice test at PSI testing centers throughout California. Once the BBC approves your exam application, you schedule directly with PSI at psiexams.com or by calling (877) 392-6422. Results are given at the testing center. The exam is available in English, Spanish, Korean, Simplified Chinese, Vietnamese, and Tagalog. Your license, once issued, must be renewed every two years with the BBC.

Hardest topics on the exam

Three content areas generate the most missed questions on the California esthetician exam. First, skin analysis — specifically the Fitzpatrick skin type scale (Types I–VI, their burn/tan characteristics, and how to select treatment protocols), transepidermal water loss (TEWL) and barrier function, and distinguishing between dry, dehydrated, oily, combination, and sensitive skin at a clinical level. Second, facial treatment contraindications — knowing precisely which conditions and medications (Retin-A, Accutane, active herpes simplex, recent chemical peels) require modified or refused services. Third, equipment and modality knowledge — how galvanic current works (iontophoresis vs desincrustation), what high-frequency ozone does, how microdermabrasion differs from chemical exfoliation. The BBC tests the science behind each technique, not just the procedural steps.

Frequently asked questions

  You must complete 600 hours of training at a BBC-approved esthetics school.

• Is the California esthetician practical exam still required?

  No. As of January 1, 2022, California eliminated the practical exam. You only need to pass the written exam.

• What score do I need to pass the California esthetician exam?

  You need 70% or higher — at least 53 correct out of 75 scored questions.

• What new services can California estheticians perform under SB 803?

  SB 803 (effective January 1, 2022) expanded the California esthetician scope to include lash and brow lamination/perming and dermaplaning, provided the esthetician has proper training in these services.

• What topics are on the California esthetician state board exam?

  Infection Control and Safety (32%), Skin Analysis and Client Consultation (20%), Skin Care Services (25%), Hair Removal (8%), and California BBC Laws and Regulations (15%).

  English, Spanish, Korean, Simplified Chinese, Vietnamese, and Tagalog per AB 451 (effective January 1, 2024).

• Can a client on Retin-A receive waxing services?

  No. Retin-A (tretinoin) thins the epidermis, making skin extremely fragile. Waxing over Retin-A-treated areas can lift skin layers along with the hair, causing severe damage. This is a standard contraindication.

• What is the difference between an esthetician and a cosmetologist in California?

  A cosmetologist (1,000-hour program) is licensed to perform hair, chemical, basic nail, and skin services. An esthetician (600-hour program) specializes in skin care, facials, and hair removal but cannot perform hair cutting, chemical hair services, or full nail services.
