What type of penalties can be imposed by state agencies on license holders?

State agencies have the authority to impose various types of penalties on license holders to ensure compliance with professional regulations and standards. The correct answer encompasses the range of disciplinary actions that can be taken against a license holder for violations such as unethical behavior, safety code infringements, or other misconduct in the nail technology field.

Warnings serve as a preliminary measure to inform the license holder about their misconduct, while fines are financial penalties imposed as a consequence of violations. Probation is a disciplinary measure that allows a license holder to continue practicing under specific conditions, giving them an opportunity to correct their behavior while still monitored. Suspension entails a temporary halt to a license holder's ability to practice, often requiring them to demonstrate compliance or improvement before reinstatement. Revocation is the most severe penalty, completely removing the license holder's ability to practice independently.

In contrast, options like interest rates on owed fines, mandatory training sessions, or public service requirements may not be standard penalties imposed by state agencies for licensing violations and could pertain to separate contexts or regulations. Therefore, the comprehensive nature of warnings, fines, probation, suspension, and revocation accurately reflects the potential disciplinary framework available to state agencies for managing license holders in the nail technology profession.
