Types of Report Writing?

I have a report on Tuesday about Report Writing but have no idea about it. We have discussed about Periodic, Progress, Projection Completion, Trip, Test/Investigation and Feasibility Reports. I searched books in our mini library and these reports are the only ones that are shown, I don't want to just repeat these reports to our class. so I am asking what could be the other SPECIAL TYPES OF REPORT WRITING? help please. Thanks so much! ^_^
