What is grounds for disciplinary action according to ABRET's Code of Ethics?

Being found ineligible to take the credentialing exam is indeed a valid ground for disciplinary action according to ABRET's Code of Ethics. This situation signifies that an individual does not meet the necessary qualifications or standards to be certified, which is a fundamental requirement for maintaining the integrity and professionalism expected in the field. The credentialing exam serves as a measure of competency and adherence to established standards. Failing to meet eligibility can reflect negatively on a professional's commitment to their practice and the ethical standards upheld by the organization.

In contrast, the other options may relate to aspects of professional conduct, but they do not directly imply a breach of ethical standards to the same extent. Minor technical errors in testing may occur in any practice and are typically addressed through feedback and improvement, while failing to complete continuing education credits may represent a lapse in diligence but may not lead to immediate disciplinary measures. Refusal to participate in professional development could indicate a lack of engagement, but it may not be as directly linked to ethical standards as the ineligibility for certification. Therefore, being found ineligible is a more serious infraction within the context of maintaining professional qualifications.
