Who was the first woman to achieve "Class A" membership in the PGA?

Barrie Naismith was the first woman to achieve "Class A" membership in the PGA. This milestone is significant as it represents a pivotal moment in the history of professional golf, particularly in breaking gender barriers within the sport. Achieving "Class A" status means that Naismith met the PGA's stringent requirements for membership, including demonstrating a high level of proficiency in golf and fulfilling educational and apprenticeship criteria set by the Association.

This accomplishment underscores the growing recognition and acceptance of women in golf, and Naismith’s membership reflects the efforts made to promote inclusivity within the PGA. The fact that she was the first woman to reach this status highlights her pioneering role and the importance of her achievement in encouraging other women to pursue careers in professional golf.

The other choices, while notable figures in the sport, did not achieve this specific milestone first, thus distinguishing Barrie Naismith's accomplishment as a landmark in PGA history.
