_TIER 1_: Proofreading, improvements to diction, sentence structure, flow and clarity. This tier is for well-written texts that require minor editing. _TIER 2_: Line editing, copy editing, in-depth improvements to language usage, organization, phrasing, scholarly tone (in the case of academic texts), style formatting (AP, Chicago, APA, or MLA) and feedback on content. For fiction, this tier includes a critique of plot development and characterization. For nonfiction and academic works, feedback identifies any unsupported or underdeveloped points or arguments.
