Well, a lot of what they expect depends on the teachers and organisation etc.
I really don't think it is much different to katate-dori. Obviously the proximity is closer, and because of that, you don't need such large movements, but otherwise, you should be able to do pretty much anything you can from a hand grab. Ikkyo, through to yonkyo at least are easy. There are also a lot of good kokyu throws that work better than a hand take because of the more direct connection.
Here is a clip of Gozo Shioda. Watch him take out the game show host at 5:30. Notice he doesn't need a very big movement because the connection is good.
