"These two instances related to identifying previous educational experience of two individuals subject to the background investigations. In one instance, the investigator was required to provide coverage of the full-time educational activity of the individual under investigation, and this did not occur. In the other instance, discrepant information was identified, and such documentation was required to be retained in the investigative file. However, the documentation was not retained. The OPM did not provide an explanation as to why the required actions did not occur," said TIGTA in the report. 

TIGTA, doing its own review of the 76 background checks using public records, found there to be no significant unreported derogatory information or missing incidents when it came to criminal behavior and dishonest conduct, including involvement in civil litigation and/or bankruptcy.
