Which requirement is essential for advertising in a school?

For advertising in a school, it is essential that the advertisement contains the school's licensed name. This requirement ensures that the institution is properly identified and that prospective students are aware of who they are considering for their education. Using the licensed name adds credibility and allows the school to comply with legal standards that govern educational advertising. It protects consumers by ensuring they are informed about the legitimate and authorized educational institution they may be enrolling in.

Highlighting student achievements, while beneficial for marketing purposes, is not a regulatory requirement. Similarly, while engaging and colorful materials can attract attention and may enhance the marketing appeal, this is not an essential requirement. Including instructor names can add credibility and a personal touch but is not mandated in the context of legal advertising requirements.
