FBLA membership is open to students from which grades?

FBLA membership is open to students in grades 5 through 12, which aligns with the correct answer. This broad range allows middle school students to begin their involvement in business-related activities and leadership development early, fostering essential skills and experiences that can be built upon as they progress through their school years. Opening membership to grades 5-12 encourages a diverse group of students to participate in FBLA, thus promoting foundational business knowledge and leadership training from a young age, which can be beneficial in their academic and professional futures.

The other options do not encompass the full range of eligibility, as some either start at a higher grade or do not include the full spectrum of middle school participants that FBLA allows.
