It absolutely will Had employees who lied for years…trip up on poly. Loss of clearance.
My advice is report, and moving forward if within timeline report it. Best to get it out now. High school limited use is a non issue if use free 12 months, and use was experimental.
Had one applicant insist his use was experimental but cited 50 to 60 times…heavy use. Even then, one could still clear if 3 or more years have gone by
