Nail Tech Written Exam 2026: NIC or PSI, and What Each Test Actually Weighs

Written & reviewed by Quibank Editor · Last reviewed 2026-10-14 · Editorial standards

There is no single nail tech written exam. Many states give one of two national tests: the NIC National Nail Technology Theory Examination (110 items, 100 scored, 90 minutes) or PSI's national Nail Technician Theory Examination, which California uses (65 questions, 60 scored, 90 minutes). Both outlines were updated for 2025–26, but not in the same way: PSI now puts half its test on safety and infection control, while NIC kept infection control at 15% and nail procedures at 60%, shifting points from consultation to tools.

So the first useful question is not "what's on the exam" but "which exam am I taking." Below is what each publisher's current outline says, what changed, and where candidates lose points.

Find out which test your state gives

Your board's exam page names it. South Carolina's says its two-part exam is NIC's, administered by Prov, with a passing score of 75% on both theory and practical. Alaska's board announced that updated NIC nail technology theory exams would be administered from January 1, 2026, and pointed candidates to the new Prov bulletin. California is the big exception: since July 1, 2022 its Board of Barbering and Cosmetology has used the national exam developed by PSI for every license type, and since January 1, 2022 it no longer requires a practical, so the written test is the whole licensing exam there.

Do not go by the vendor name on your admission letter. PSI also delivers NIC's exam in some states: Virginia's 2022 bulletin, for example, is a PSI document that contains NIC's theory outline. The exam title in your bulletin, NIC National Nail Technology Theory or PSI Nail Technician Theory, is what tells you which content outline to study.

The NIC theory exam: procedures carry 60%

NIC's current Candidate Information Bulletin (effective September 1, 2025, revised March 1, 2026) splits the 100 scored items across eight domains:

Infection control and safety practices: 15%
Anatomy and physiology: 15%
Chemistry of nail products: 10%
Pre-service process (consultation and work area preparation): 5%
Nail service tools: 13%
Manicure and pedicure services: 18%
Nail enhancement application, maintenance and removal: 20%
Post-service procedures: 4%

The three scientific domains add up to 40%. The single largest domain is enhancements, which the outline lists as nail tips, acrylics, soft, hard and hybrid gels, and powder dip. NIC's own sample questions show the register: what is the first step of a manicure (remove old polish), where nerves and blood vessels sit (the nail bed), what goes on a split nail before wrapping (adhesive glue). These are sequence and identification questions, which is why the procedures domains reward someone who has actually done the services in order.

What NIC changed from its 2020 outline

Comparing the current bulletin with the 2020 version (still the outline in Virginia's 2022 bulletin) shows where the points moved:

Client consultation (5%) and service preparation (5%) were merged into one 5% pre-service domain, so that material lost half its weight.
Nail service tools rose from 8% to 13%, and safe use now covers supplies and equipment as well as tools.
"Light-cured gels" became soft, hard and hybrid gels; powder dip stayed.
Gel polish and masks with essential oils dropped out of the add-on services; exfoliation moved there, and polishing and removing massage product were added to the basic manicure steps.
New lines appear on safe handling and storage of chemicals, ingredients that may cause harm, and the joints of the arms, hands, legs and feet.

If your school's study guide predates 2025, it is overweighting consultation and underweighting tools by roughly five points each.

PSI's exam: half the test is safety

California's board sent schools a memo on November 21, 2025 announcing PSI's updated outlines, implemented April 1, 2026. The nail technician changes are larger than NIC's:

Safety and infection control: 38% to 50%
Client consultation and nail analysis: 13% to 18%
Skin care: 0% to 10%
Nail care: 49% to 22%

Half of 60 scored questions is about 30 on safety. That domain goes beyond disinfection: it lists the three levels of decontamination, single- and multi-use items, exposure-incident procedures, safe water temperature, electrical safety, ventilation, and federal rules from OSHA, EPA and FDA. Enhancements are now one subsection inside the 22% nail care domain, while the new skin care domain covers manicure and pedicure massage, hot towels and safe callus removal. Consultation questions focus on contraindications: when to decline or alter a service, and when to tell a client to see a doctor.

PSI uses a criterion-referenced passing score rather than a fixed percentage. Pass in California and its bulletin says you receive your license on site; fail and the notice shows your score, a breakdown by content area, and the number of correct answers you needed.

Where candidates lose points

PSI shared item statistics for the 2020-outline nail exam at the California board's Q1 2026 town hall. English-language candidates averaged 84% correct on safety and infection control, 85% on nail analysis and 82% on nail care. Spanish-language candidates averaged 74% on safety and 70% on nail care, gaps of 10 and 12 points, and PSI flagged exactly those two areas as needing extra instructional emphasis for Spanish speakers.

Two takeaways. Safety is now half of PSI's scored questions, so if a 10-point gap held on the new exam it would cost about three questions on safety alone. And if you test in translation, learn the English term alongside your own. California's board posts PSI translation guides for Spanish, Vietnamese and Simplified Chinese, and you confirm your language when you schedule.

Study for the version you are taking

For NIC, budget your time the way the outline does: enhancements, manicure and pedicure steps, and tool identification together are 51% of the score. Practice saying each service out loud in order, from removing old polish to post-service cleaning, and know what each implement is for. Our services and procedures section is the closest match.

For PSI, flip it. Drill the difference between cleaning, disinfection and sterilization, what happens to a porous file after one client, and what you do after a blood exposure. When a question describes a client with redness, swelling or a suspected fungal infection, the answer is almost always to decline the service and refer them out. Start with the infection control and safety section.

Either way, our three practice sections are evenly sized, so they do not mirror either exam's weights. Use your weakest section's score to decide where to spend time, and revisit missed questions on the mistakes page until the explanations make sense without the answer.
