The U.S. Department of Education (Department) Office of Inspector General (OIG) Strategic Plan for fiscal years 2018 through 2022 describes the focus and direction of OIG's operations over the next five years, establishes their organizational goals, and outlines the strategies they will employ to reach those goals and the measures they will use to evaluate their performance. OIG's mission is to promote the efficiency, effectiveness, and integrity of the Department's programs and operations. To achieve this mission, OIG conducts audits and investigations and provides other assistance to help ensure integrity in the Department's operations and programs and identify opportunities for improvement. The information OIG provides to Department managers and the U.S. Congress can result in changes to legislation, regulations, policies, and practices. These changes are designed to continually improve the operations of the Department and its programs so they best serve America's taxpayers and students. In developing this plan, OIG considered the Department's mission, strategic plan, and management challenges; major educational program development and initiatives; and the OIG's statutory responsibilities. Plan sections include: (1) Office of Inspector General Roles and Responsibilities; (2) Overview of Office of Inspector General Strategic Plan for Fiscal Years 2018-2022; (3) Strategies and Performance Measures; (4) Office of Inspector General Areas of Responsibility; (5) Key Factors that May Affect Achievement of Our Goals; (6) Relationship of OIG's Strategic Plan to Government-Wide and Department Goals and Objectives; and (7) Program Evaluation.
