This document presents the 50th semiannual report on the activities and accomplishments of the Office of Inspector General (OIG), U.S. Department of Education (Department). During this reporting period, the OIG issued 123 audits, inspection reports and memoranda, and closed 95 investigations. As detailed in this report, this office continues to leverage very limited resources on the programs and operations that are judged to present the greatest risk to the efficient and effective accomplishments of the Department's mission.

This report highlights the most significant work from the last six months, reflecting the strong commitment and valuable role in assisting the Department in improving its programs and ensuring their integrity. An appendix identifies and describes the management challenges of the Department.
