This document provides guidance on creating an effective working outline for an argumentative essay. It explains that outlines are useful for longer compositions that use sources and develop a logical argument. The key parts of a working outline are then defined, including the title, thesis statement, introductory rationale, main supporting claims, evidence, counterarguments, and concluding rationale. For each section, advice is given on how to develop that part of the outline. Students are reminded that the outline is a roadmap for their writing but may require some flexibility.
