The Federal Bureau of Investigation is planning to test agents about their understanding of the bureau’s surveillance guidelines, a move coming more than a year after the Justice Department discovered widespread cheating on the exam.

Testing covering the recently amended Domestic Investigations and Operations Guide is to commence in the “coming weeks,” according to the Main Justice blog.

The Justice Department’s inspector general concluded last year that a “significant number” of the 14,000 agents cheated on the required, open-book test given in 2009.

“In our limited investigation, we found that a significant number of FBI employees engaged in some form of improper conduct or cheating on the DIOG exam, some in clear violation of FBI directives regarding the exam,” (.pdf) the inspector general’s report noted.
