At which conventions was the FFA creed revised?

The FFA creed was revised at the 38th and 63rd National FFA Conventions. The revisions were part of a broader effort to modernize and reflect the evolving goals and values of the organization. The first significant revision at the 38th convention in 1966 involved changes to language that made it more inclusive and relevant to the diverse membership of the FFA. The subsequent updates at the 63rd convention in 1991 continued this trend, ensuring that the creed resonated with newer generations of members while maintaining the core values of agriculture and leadership.

Other options may list specific conventions, but they do not align with the documented history of the creed's revisions, which are important for understanding the FFA's commitment to adapting its foundational principles over time.
