Minimum standards of character are established by an employer and refer to identifiable character traits and past conduct. An employer may use character traits and past conduct to determine whether an applicant, volunteer, or employee can effectively perform the duties of a particular position without risk of harm to others. Minimum standards of character ensure that no applicant, volunteer, or employee will be placed in a position with regular contact with or control over Indian children if he/she has been found guilty of or entered a plea of nolo contendere or guilty to any felonious offense, or any of two or more misdemeanor offenses under Federal, State, or Tribal law involving crimes of violence; sexual assault, sexual molestation, sexual exploitation, sexual contact or prostitution; crimes against persons; or offenses committed against children.
