Which of the following is not a requirement for obtaining an esthetician license?

Submitting a business plan is not a requirement for obtaining an esthetician license. The process to acquire an esthetician license primarily focuses on demonstrating proficiency in esthetics through practical and theoretical knowledge, which is achieved by completing required training hours, passing a written exam, and meeting specific age requirements.

Completing required training hours ensures that the candidate has received adequate education in the field, covering topics like skin care, treatments, and safety protocols. Passing a written exam assesses the candidate's understanding of esthetic principles, laws, and regulations, ensuring they are knowledgeable enough to perform their duties effectively and safely. Meeting minimum age requirements is also a standard criterion to ensure that candidates are mature enough to handle the responsibilities associated with the profession.

In contrast, the submission of a business plan is typically not part of the licensure process for estheticians, as the focus is on individual competency rather than business acumen. Thus, option C is the correct choice because it does not align with the essential requirements for obtaining licensure in esthetics.
