To support these changes in audience, tone, and purpose, policy briefs have a distinctive format. You should consult your assignment prompt and/or your professor for instructions about the specific requirements of your assignment, but most policy briefs have several features in common. They tend to use lots of headings and have relatively short sections. This structure differs from many short papers in the humanities that may have a title but no further headings, and from reports in the sciences that may follow the “IMRAD” structure of introduction, methods, results, and discussion.
