Honestly, I didn’t realize Invitationals was harder than Nationals.
I have several friends attending this multi-sport national championship event in March. They do not trial every weekend, not at all. I’m driving up with friends for one day. I’m looking forward to watching a wide variety of breeds -and shopping :D. That is the great thing about AKC events, all kinds of weird breeds! If I saw a Groen or PBGV on the street, I would assume it was a mix. :lol:[/QUOTE]
Yep, that’s Nationals and I’ll be there with two dogs - one doing agility, one doing Rally.
Caveat - all that follows is based on Agility and Rally - the Obedience National Championship criteria is a little different, and can be found here: http://www.akc.org/events/obedience/national_obedience_championship/2014/criteria.cfm
For Agility and Rally, qualifying for Nationals is “easy” - for agility, (this year, at least) you needed 400 MACH points, 4 double Qs and a total of 20 Qs out of Masters Standard and Jumpers (the doubles did count towards your 20 total). For Rally, 3 scores of 90 points or better and the title achieved during the qualification period. (RAE is a little more complicated, but the same general idea.) Qualifying period ran 12/1/12 to 11/30/13 for both.
I say that it’s “easy” because basically, you meet the requirements, and you’re in (assuming you got your entries in on time - Agility was unlimited entry, but Rally was pretty limited).
Invitationals is different - only the top 5 of each breed get invited - doesn’t matter how well you and your dog do personally, what matters is how well you do compared to others of your breed. If you’ve got a popular breed for agility, you have to be VERY good to make that top 5 - there are an awful lot of Pemmies and Border Collies and Shelties and Paps out there, and to be one of the top 5 and hold that spot means lots of trialing. If however, you’ve got the only Laekenois or one of the only two Beaucerons that are out there running at the Master’s level, then yep, it is easier to get in. But if you’ve got one of 500+ Border Collies? Not so much.
To my mind, qualifying for Nationals is an achievement - it’s something that you can work towards and accomplish in the absence of pretty much anyone else. You get your Qs, you get your points - you’re in. Invitationals is an honor, but what you do is all relative to what other folks are out there doing, so you have less “control” over whether you achieve that goal or not. I’m not sure I’m conveying this very clearly, but it is totally clear in my head! 
And like I said, this only goes for Agility (and Rally) - I know that Obedience Nationals is more like an Invitational than the other two sports, but that’s about the extent of my OB knowledge. If your goal is a run at Obedience Nationals, more power to you! I have neither the love nor the patience for it.
