On the other hand, barring reasonable accommodations, if a person is physically or mentally incapable of performing the minimum requirements for a particular rank, I don't think a promotion should be given... ever. This idea that eventually everyone gets a black belt if for no other reason than that they have stuck around devalues the rank for everyone, including the person in question.
What is your idea of reasonable accommodations? Just out of curiosity?
Good question. I would say that requirements should be results oriented. For example, BJJ is probably better suited (organizationally) for some who are physically disabled than some styles because promotion is tied less to specific techniques. While it's important for a white belt to understand armlocks, shoulder locks, guard, 1/2 guard, 100 kilos, knee on belly and mount both offensively and defensively, the measure for promotion is application. A person with no legs, for example, can clearly not close guard. Knee on belly is out. Many armbars are out.
But because BJJ is more results oriented, if a person without legs can attack and defend while grappling, at a level of proficiency comparable to other blue belts, there's no reason he or she should be kept from promotion.
In the same way, if kicking (whether generally or specifically) is considered critical to the style, it may very well be impossible for a person who is in a wheelchair to advance in rank.
If this person can meet the general criteria, however, attacking and defending within the scope of the style, I'm all for it.
The main point is, are you figuring out ways in which a disabled person is able to meet the standards everyone else is required to meet, or are you lowering the standards? If the latter, this isn't a reasonable accommodation.
But (and this is a big but), whether or not a person will ever earn a black belt, training can still be very beneficial. And I'd argue that a green belt truly earned is much more valuable than a black belt given as a gift.
