INI-SS

It combines a multiple-choice paper, a written examination, and a practical assessment. Questions span nine domains, from infection control and nail anatomy through artificial enhancements, nail art, client consultation, product chemistry, and salon law. Expect the practical portion to be judged on technique and safety habits, not only on the finished look.

Those figures are set by the certifying body and change between blueprint revisions, so this page does not quote them. Before you book, check the official International Nail Institute website or candidate handbook for the current question count, time allowance, and section breakdown, and plan your practice sessions around those numbers.

The passing standard and the exam fee are published by the official body and are not stated here because they were not confirmed against a current source. Contact the institute directly or consult its candidate handbook for the current passing score, fee schedule, and any separate practical-assessment charges.

Candidates with solid salon experience usually find the technical domains manageable but are surprised by the breadth of the business, law, and chemistry content. The practical section is where unprepared candidates lose ground, because safety and sanitation habits are observed directly. Breadth, not trick questions, is the usual challenge.

Retake rules, waiting periods, and any additional fees are set by the certifying body and are not published on this page. Ask the institute about its current retake policy before you sit the exam, and find out whether a failed practical section can be re-attempted separately from the written sections.

Validity periods and renewal or continuing-education requirements are determined by the official body and were not confirmed for this profile. Check the institute's site for the current validity term and renewal process, and keep records of your training hours in case renewal requires documentation.

Start with infection control and anatomy, since every other domain depends on them. Then work through disorders and contraindications, natural nail care, and enhancements. Add nail art and finishing once technique is stable, and leave consultation, chemistry, and salon law for the final weeks so they stay fresh.

Weak sanitation habits during the practical, shallow knowledge of contraindications, and skipped business and regulation material. Candidates who only rehearse application techniques often cannot explain why a service should be refused or how a product works. Practicing explanations out loud closes much of that gap.

Rehearse full services end to end under time pressure, including setup, disinfection, client communication, and cleanup. Have a mentor score you against a checklist covering tool hygiene, product control, and nail shape consistency. Repeat the same service several times rather than sampling many styles once.

No. No official source document was supplied, so the domain list and weights shown are provisional and may not match the current outline.
