Heh! Heh! Know that, been there done that! Novice A in either Rally or Obedience is a novice beginner class and i would expect a not very good pass ratio.
But if they have a good instructor, he/she should cut that a bit by discouraging entry in a real trial before they are ready.
I like the approach I have seen from a couple of real good instructors in different training venues.
That is "Teach", "Generalize" and "Proof".
Not until we get near 100% in Proof situations with many distractions, etc. would I even consider actual trialing.
I like to do it this way so I don't have to use the fourth phase - "Make Excuses". Like too hot, too cold, too wet, too many people around, the judge made me do it, the other dog made him/her blow it, my wife/husband/son/etc. can't be at ringside, etc.
This last phase can be fun and we can all get really creative.
My last dog blew his last Rally trial (before DM appeared) by reacting briefly (quick turn and bark before returning to a nice heel) when 2 big dogs lunged at him as we heeled by the rope ring "fence".
Earned an NQ from the judge for that. Fortunately we did have a complete video of our whole run thanks to a friend; so we could see his (and mine) performance.
But I don't think he should have reacted even if the dogs did lunge and bark as we walked by. It was a reason, not an excuse. But also not a pass!
