What is the maximum number of clients an apprentice can service at once?

The correct answer is based on the regulations governing cosmetology apprentices in Massachusetts. In this context, an apprentice is not fully licensed and is still in a training phase under the supervision of a licensed professional. To ensure that apprentices receive adequate supervision and training, there is a limitation on the number of clients they can service at a single time. Allowing an apprentice to service only one client at once ensures that they can focus entirely on that client's needs while being closely monitored by their supervisor. This structure helps maintain high standards of safety and quality in services provided to clients and allows for a more effective learning environment for the apprentice.
