The number of references to include in the reference form vary based on the recipients' requirements or preferences. In general, it's best to include a minimum of three diverse references. Doing this allows recipients to gather a well-rounded perspective on your qualifications and work history. It is important to choose references who can answer honestly, highlight your best qualities, and offer a reliable reference. Selecting individuals from different professional backgrounds, such as supervisors, colleagues, coaches, or mentors, can provide a more comprehensive assessment and show you are well-rounded.
