I completely agree with your frustration!  Last year I had 1,......1 company that would not accept the NNA background check I had, and would only take Sterling, so I thought ok I will go ahead and pay the additional money and hope to get more business from this company, but was furious, and speechless that they would not accept the NNA background check I already had. Now with the new year I needed to renew some of my credentials, but hey I already had an up to date background check ( with Sterling ) so I sent that one out to my contacts, and only 1 out of 10 would accept it.  When is the nickel and diming going to stop against us independent contractors? 

I would think the background check through the NNA would be the only one you would need???
