How this list was compiled: Idaho Code Title 54, Chapter 58, the Barber and Cosmetology Services Act (sections 54-5801 to 54-5827), on the Idaho Legislature's own site (https://legislature.idaho.gov/statutesrules/idstat/Title54/T54CH58/); and IDAPA 24.28.01, Rules of the Barber and Cosmetology Services Licensing Board, in the current copy on the state's administrative rules site (https://adminrules.idaho.gov/rules/current/24/242801.pdf). Each question names its section or rule and links to the document it is in. Read 2026-10-09. Licence: Own work. Every question, wrong choice and explanation was written for this site from the statute and rule text. Nothing comes from a testing vendor, a textbook, a prep course or an exam question pool.
How it works
This unofficial Idaho cosmetology law practice test asks only the Barber and Cosmetology Services Act (Idaho Code Title 54, Chapter 58) and the Board's rules (IDAPA 24.28.01), read on October 9, 2026. Hair, skin and nail theory is left out.

What the Idaho law questions cover
Licenses, schools and apprenticeships make the largest group, because the Act sets training hours and endorsement terms and the rule sets apprenticeship weeks. Then come safety and disinfection, scope of practice and exemptions, establishments and inspections, prohibited acts and discipline, renewal and display, and the Board.
Where Idaho law sits beside the state's examinations
Idaho Code 54-5809 requires a practical demonstration and a written test, and the rule approves national written and practical examinations (IDAPA 24.28.01.100.01). Neither text sets out a separate Idaho law test, so this page describes none. Idaho Code 54-5815 puts the Idaho laws and rules in every school's curriculum, and that material is what this bank drills.
A cosmetologist needs 1,600 school hours or 3,200 apprentice hours, and a student may test at 80 percent of the hours (Idaho Code 54-5810).
Ultraviolet light does not count as disinfection, and bleach must be under six months old (IDAPA 24.28.01.002).
An unacceptable C classification at inspection gives an establishment thirty days to improve (IDAPA 24.28.01.200.05).
Questions and answers
Is there a free Idaho cosmetology law practice test?
This page is one. It is free, it asks Idaho's own statute and Board rules, and the section sits under each answer so you can open the law and check it. It is unofficial.
Is this a cosmetology practice test for the Idaho state board exam?
Not for its theory. The Board's rule approves national written and practical examinations (IDAPA 24.28.01.100.01), aimed at general knowledge of the practice and the ability to do the work (Idaho Code 54-5809). This page asks Idaho law and rules only.
Does Idaho have a separate cosmetology law exam?
The Act and the Board's rules, as read on October 9, 2026, name only the written and practical examinations. Idaho law is still required teaching in every licensed school (Idaho Code 54-5815). Ask the Board what your application needs.
Are these real Idaho exam questions?
No. Nobody here has seen a licensing examination. Each question was written from Idaho Code Title 54, Chapter 58 or IDAPA 24.28.01, and the Idaho Barber and Cosmetology Services Licensing Board did not write or review any of them.
