Which of the following is required to establish good moral character for certification?

To establish good moral character for certification, it is essential to understand that the process typically entails an informal interview conducted by the board. This interview provides a platform for assessing the applicant's character through direct interaction. The board can evaluate the applicant's responses and demeanor in real-time, which allows for a more personal assessment of the individual’s morals and ethical standards.

The requirement for an informal interview highlights the importance of subjective judgment in evaluating good moral character, as it allows the board to assess not just written or third-party references, but also the individual's integrity as communicated during the conversation. This interaction can help clarify any concerns and provide a comprehensive view of the candidate's character.

While other options like written essays, references from previous employers, and criminal background checks serve as tools for evaluating different aspects of a candidate's qualifications, they are not necessarily aimed at gauging the deeper, personal attributes that are encapsulated by an individual's moral character.
