A referee’s statement (or reference) is a written recommendation from a teacher, advisor or professional who knows you academically. Everyone needs a reference, unless you get permission not to submit one from your chosen universities and/or colleges. This reference must be completed and added to your application before it is submitted.
If you’re attending school or college, your referee will usually be a form tutor or teacher. You may have a particular referee in mind, and you can have a conversation with them directly to see if they are happy to fulfil this part of the application for you. A referee needs to be somebody who can talk about your work ethic, interaction with other students and your suitability for higher education or a future career.
