What must a candidate do if they fail the written examination?

A candidate who fails the written examination has the opportunity to retake it under specific conditions, which aligns with the selected answer. This approach allows individuals to learn from their previous attempt and prepare adequately for the next try, providing a second chance to demonstrate their understanding of the material.

The conditions typically involve a waiting period or specific guidelines that the candidate must meet before they can retake the examination. This structure is designed to ensure that candidates have the opportunity to improve their knowledge and skills, rather than facing premature disqualification or an indefinite wait period, which might be more discouraging and less productive for their professional development.

With this understanding, it's clear why the selected answer emphasizes the chance to retake the examination with certain stipulations, fostering both accountability and growth in the certification process.
