In the actual OIG report, it seemed the person who gave "answers" to the test didn't actually have the behavioral test or the answer key.

He stated he stressed things like answering questions like an air traffic control "and we’re alpha personalities, we’re dominating, we don’t take no for an answer." He also mentions that he got calls, from multiple people, saying they failed the behavioral test.

So it seems that while he did coach answers, they weren't the literal test answers, but rather advice one could have gotten from public sources with enough research or presumably, talking to some FAA air traffic controllers.

In the end, the report stated the findings in the investigation did not warrant a referral to a federal prosecutor.
