A type of writing produced by students in an academic setting or everything written in relation to school are for academic purposes. Impersonal - it usually uses third person perspective and does not have direct reference to persons and feelings. Formal - because it strictly adheres to formal English and avoids word contractions (don't, shouldn't), avoid using personal pronouns, and less factual. You also need to build a wide-ranging, field-specific vocabulary that are exclusive to a specific field of study such as psychology, medicine, linguistics, and sciences.
