I don't know the school I worked at had a standard 3 circuit checkout.
I did ask the boss if we shouldn't be doing more and he just said no it just annoys the punters.
And to be fair during the summer we had 4 aircraft in the air for 7 plus hours a day. And in the year I was there we didn't have any incidents.
But then again we got a lot of unrequired requests for instructor flights. Maybe the fact that the punters didn't feel they were getting shafted for check flights and skills tests every time they came in made them less bitter and twisted about going up with an instructor.
