I know the following were the first years that the poly was used by the FBI and ATF for Special Agent positions:
FBI- 1994
ATF- 2001
Thanks.
If I'm not mistaken, CIA officers are not "special agents" in the sense that federal law enforcement officers are. While I'm not sure when polygraph screening became a general requirement for CIA employees, the CIA polygraph program was set up in 1948 by Cleve Backster (http://www.backster.net) (who didn't stay long).
