Free Practice Questions for CO Nail Technician

Colorado requires applicants to be at least 16 and to complete 600 contact hours or 20 credit hours at a DPOS- or CCCS-approved school or an approved apprenticeship (C.R.S. 12-105-111; 4 CCR 731-1, Rule 1.2). Applicants then apply through PSI and pass the PSI practical test followed by the PSI theory test. Proof of lawful presence is no longer required under SB21-077.

The PSI theory test has 60 scored multiple-choice questions plus 5 unscored experimental questions, with 90 minutes to finish and a 70% pass mark. The outline is 50% Safety and Infection Control, 18% Client Consultation and Nail Analysis, 10% Skin Care, and 22% Nail Care. It has no separate Colorado-law section.

The practical comes first. PSI's Colorado guide says test takers must pass the practical test before they can pay for and schedule the theory test. The practical has five timed topic areas totaling about 90 minutes: workstation preparation, basic manicure, nail tip application, nail enhancement using a form, and preparation for the next client.

PSI lists a $32 application fee, $69 for the practical test and $62 for the theory test, or $163 for a first attempt at both. Retakes cost $67 for the practical and $60 for the theory test. Test fees are nonrefundable and valid for one year.

Yes, after extra training. 4 CCR 731-1, Rule 1.9(F) requires 8 hours of electric-file training before using an e-file, and craft or hardware tools are excluded. Rule 1.9(G) allows waxing or depilatories on the hands, feet, arms to the elbow and legs to the knee after 6 hours of training.

Rule 1.8 of 4 CCR 731-1 prohibits MMA liquid monomer, live fish or other creatures, banned or unsafe products, and UV light boxes for disinfection. It also bars any technique that goes beyond the epidermis or is reasonably likely to injure the client. Possessing a prohibited item is prima facie evidence of using it.

Colorado barber and cosmetology licenses renew every two years; the most recent cycle expired March 31, 2026, with renewals accepted through May 31, 2026. Rule 1.5 gives a 60-day grace period after each expiration date during which licensees may keep working. Name and address changes must be reported within 30 days.
