I have used King for both my IRA and FII as well as my commercial. I am close to being ready to taking my FIA written. The proctor told me last week that a endorsement is not needed for the FIA or FOI. I just want to confirm before I drive to another state to get turned away.

Correct. No endorsement required. You can also confirm that on the testing providers websites. Good luck.

Ok thanks for the response. I wonder why ATP and CFI's don't require an endorsement. I guess they figure by the time you get to that level you aren't going to take a test until your ready?
