(4) Ensuring that departing officials receive a m andatory briefing and that all departing officials will execute a Form SF-312, Classified Information Nondisclosure Agreement certifying that they have not have not have not retained in their possession classified or administratively-controlled documents.
The other is the wrong one apparently.
This is the new form...STANDARD FORM 312 (Rev. 7-2013)
7. I understand that all classified information to which I have access or may obtain access by signing this Agreement is now and will remain the property of, or under the control of the United States Government unless and until otherwise determined by an authorized official or final ruling of a court of law. I agree that I shall return all classified materials which have, or may come into my possession or for which I am responsible because of such access: (a) upon demand by an authorized representative of the United States Government; (b) upon the conclusion of my employment or other relationship with the Department or Agency that last granted me a security clearance or that provided me access to classified information; or (c) upon the conclusion of my employment or other relationship that requires access to classified information. If I do not return such materials upon request, I understand that this may be a violation of sections 793 and/or 1924, title 18, United States Code, a United States criminal law.
Keep this in mind...The FAS has a blog post on the new document which notes that sections 10 and 11 are new.
Yep, here it is...FORM OF-109, SEPARATION STATEMENT
...or administratively-controlled documents...
It's the same wording.
It seems there are two forms that need signing upon exit.
What say you then about Form SF-312 in reply 28?
