Which of the following is prohibited under Minnesota nail school law?

Performing services without a valid license is explicitly prohibited under Minnesota nail school law. This regulation is in place to ensure that all practitioners have met the necessary training and competency standards to provide services safely and effectively. Licensing serves as a way to protect both the professionals and the clients in the nail care industry, ensuring that individuals have the required knowledge, skills, and hygiene practices before offering services.

Operating without a license can lead to significant penalties and legal consequences, as it undermines the integrity of the profession and can put clients at risk of unregulated practices. Maintaining a licensed profession helps build trust between clients and service providers, ensuring that all services provided in Minnesota meet health and safety standards required by state law.

In contrast, the other options, such as working with a reduced fee, offering free consultations, or accepting tips, do not inherently violate the regulatory framework established for nail professionals. These practices can be part of a legitimate business model as long as they comply with other relevant laws and regulations, including those related to pricing and workplace conduct.
