This document provides guidance on writing effective abstracts for reports. It outlines three types of abstracts - informational, descriptive, and qualitative. An effective abstract uses well-developed paragraphs in an introduction-body-conclusion structure to summarize the purpose, findings, conclusions, and recommendations of the report in a concise yet intelligible manner for a wide audience. Tips are provided to write abstracts that are easy to read, concise, exact, and unambiguous using an organizational scheme that clearly conveys the information to the reader.
