This ninth semiannual report issued by the United States Department of Education's Office of Inspector General (OIG) summarizes the activities and accomplishments of that office during a 6-month period ending September 30, 1984. A condensation of audits of Department of Education aid programs presents statistics on OIG activities and the allocation of audit resources, highlights of significant audits (many of which recommend recovering misspent federal funds), and information of progress toward resolving various audit recommendations. Investigation activities are also noted, including highlights of cases presented and an update of previously reported investigation. Descriptions of steps taken by the OIG to improve the management of internal operations and aid programs covers documents that evaluate or prescribe management practices, as well as internal control reviews and measures to improve the disposal of funds. Miscellaneous other matters reviewed include legislation and regulations affecting the economy of the department. Appendixes include a list of audits for the period covered in the report and a schedule of accounts receivable. Finally, two guides to ethical conduct issued by the OIG are exhibited. (MCG)
