To meet the Board's licensure requirements, you will be required to nominate a minimum of three references. They should be professional members who have supervised your work. If there have not been three professional members in your career who have been your supervisors, the Board will allow references from professional members who are familiar with your work, such as co-workers, mentors and clients. As an alternative, the Board may allow references from supervisors who are not professional members, in certain cases.
