Which of the following is NOT a form of membership in the FFA?

The correct answer is "Advisory," as it does not represent an official form of membership in the FFA, which is the Future Farmers of America. The forms of membership recognized by the FFA include Active, Collegiate, and Honorary memberships.

Active membership is designed for students who are currently enrolled in agricultural education programs and are actively participating in FFA activities. Collegiate membership caters to students who continue their FFA involvement while attending college and are enrolled in courses related to agriculture or leadership. Honorary membership recognizes individuals who have made significant contributions to the FFA and agricultural education but do not meet the criteria for Active or Collegiate membership.

On the other hand, "Advisory" is not an official membership category recognized in the FFA structure. While advisors play a crucial role in guiding and supporting FFA members, their role does not equate to being a member in the traditional sense as outlined in the FFA bylaws. Therefore, "Advisory" is the appropriate answer to the question of which option is not a form of membership.
