Which element related to star ratings is NOT required during a formal marketing/sales event?

During a formal marketing or sales event, displaying all plans within the same star rating group is not a requirement. This means that while it can be beneficial to include various plans to provide a comprehensive view of options available to potential enrollees, there is no obligation to present all plans together simply because they share the same star rating.

In contrast, it is essential to provide a list of plans with different star ratings, offer a clear explanation of those ratings, and clarify the significance behind the ratings. These elements ensure that consumers are informed about the quality and performance of the plans they are considering, ultimately allowing them to make more educated decisions concerning their healthcare options. The focus during such events is to help potential customers understand how star ratings function and how they can impact their choices, rather than just clustering plans based on identical rating groups.
