Which event in FBLA is solely for members in grades 9-10?

The event known as Principles and Procedures is specifically designed for members in grades 9-10, making it distinct in the context of the FBLA competition structure. This event focuses on teaching foundational knowledge about the operations and structure of FBLA, as well as basic business concepts. It emphasizes understanding principles relevant to members who are just starting their journey in business education and FBLA involvement.

The other options represent events that are open to a wider range of participants, including those in higher grades. Business Plan and Entrepreneurship are aimed at individuals who may have more experience and are looking to apply advanced concepts, while Word Processing tests skills that could be relevant for all members, not limited by grade level. This differentiation ensures that members at the beginning of their high school experience have the opportunity to engage in a competition that is suitable for their skill level and knowledge base.
