Which of the following is NOT an occurrence that must be reported to the commission?

The correct choice highlights that personal income is considered private financial information and not directly relevant to the operational integrity or trustworthiness of a private investigator. The Tennessee Private Investigator Licensing Act emphasizes the need for the commission to be informed about changes that could affect a licensee's ability to perform their duties ethically and legally.

Criminal charges, punitive judgments, and material changes in previously submitted information are critical to maintaining accountability and transparency in the profession. These occurrences can significantly impact a licensee's fitness for duty or professional conduct, raising the need for notification. On the other hand, changes in personal income do not typically pertain to the responsibilities and ethical standards expected of a private investigator, making them non-reportable to the commission.
