Which of the following is a reasonable qualification for membership in a professional organization?

The qualification of a requisite educational background or achievement is a reasonable and common criterion for membership in a professional organization. This requirement ensures that members possess the necessary knowledge and skills relevant to the profession, which can enhance the quality and credibility of the organization. Professional organizations often seek to promote standards and advocacy within their field, and a focus on education and achievement can help in maintaining these standards.

Setting educational requirements allows organizations to attract individuals who are serious about their professional development, thereby fostering a community of competence and excellence. This approach aligns with the objectives of many professional associations, which aim to support continuous learning and professional growth among their members.

In contrast, a minimum age requirement does not necessarily reflect professional competency, and restricting membership to individuals from only select organizations may limit diversity and hinder collaborative opportunities. Moreover, focusing solely on high sales volume could exclude talented professionals who may not have high sales figures but possess valuable skills and knowledge contributing to the profession's advancement.
