All of these are a prerequisite for becoming a licensed agent EXCEPT

To become a licensed insurance agent in Florida, there are specific prerequisites that one must satisfy, each designed to ensure that candidates have the necessary knowledge and integrity to perform effectively in the industry. The option indicating the necessity of graduating from high school is not a strict requirement under Florida law, which is why it is the correct choice here.

While obtaining a background check is essential to assess the candidate's criminal history and to ensure they meet the moral character standards required by the state, completing pre-licensing coursework is imperative as it equips potential agents with the knowledge about insurance products, regulations, and ethical considerations. Additionally, passing the state licensing exam is a crucial final step demonstrating competency in the relevant insurance laws and practices before one can be granted a license.

Thus, while obtaining a high school diploma may be beneficial for personal development and might be encouraged by some agencies, it is not enforced as a mandatory requirement by the state of Florida for obtaining an insurance agent license.
