Not sure how similar it is in other places, but in Australian tournaments the system is Open grade, then A-D. I don't know what others feel about this grading system, but I have issues with it, starting with the naming of the grades. There are two issues I have with the system in place here. Firstly, there's no clear differentiation between the standard in each grade. The D grade players are really good, and I was told a lot of the best players in my club have come down to Sydney thinking they'd do well in D grade singles, only to lose first round. Which leads me to my next issue. If you asked a student their grades and they said they were a D grade student you'd think they were pretty bad. So if you get smashed in D grade it wouldn't make you sound very good if you reported it to a non-player. Wouldn't it be better for some people's self-esteem to dispose of a letter grading system, and use euphemisms instead? Use of euphemisms has been attempted in table tennis here. The local club has usually had four grades, and the bottom grade has usually been called B or B2, but never D grade. Tournaments here for a while had a similar system to badminton with Open and A-E grades, however there was a clear distinction between grades. A rating system was established, and only players of certain ratings and lower can play some grades. However recently they obviously thought using euphemisms was the thing to do, as they have eliminated letter grades. Now on an entry form it will for example say <= 1900 singles. If a badminton association doesn't have a rating system, wouldn't it be better to call the grades say Open, then Division 1-4? If you say you are a Division 4 player people often wouldn't even know you are in the bottom grade.
