Military background checks not re-examined for a decade unless concerns raised

People who seek "secret" security clearances to work at U.S. military installations undergo background checks that are good for a decade and are not re-examined unless derogatory information is presented to authorities, defense officials said on Wednesday.
The department is working on a pilot program that would automatically send records of arrests or criminal charges to the appropriate defense officials. But the project is in the early stages and the Pentagon depends largely on individuals or their supervisors to report any misconduct, officials said.
"There's a requirement for self-reporting. And clearly, someone who is engaged in illegal behavior is not necessarily going to be disposed to self-report," one official said on condition of anonymity.
