I think a couple of points in my original post may have been misunderstood by some people (perhaps because I did not go into enough detail and perhaps because I am basically making this up as I go along):
1) When I mentioned a "standard curriculum" I was not suggesting that we would force teachers to use this curriculum in their classes. As Phil suggested, this is something that teachers could choose to use as they saw fit. I suspect that many teachers would appreciate such a service for several reasons (not the least of which it would save them from doing a lot of work themselves). Also, probably many students, especially beginners and intermediates, might prefer to seek out teachers who used such a curriculum (because this would be just about the only way they could know that what they were being taught was considered "mainstream").
2) Agree with those of you who think that the whole concept of accreditation would be complicated. However, as Hrothgar pointed out, if BBO gets into this business then we have to take some responsibility for quality control. To me this means that we would have to make some effort to ensure that all accredited teachers are:
- honest
- polite
- know the basics of how our software works
- know how to type at a reasonable speed
- know enough about bridge to teach the subjects they want to teach
- are sufficiently fluent in the language(s) that they plan to teach in
This sounds complicated, but I would hope that we could find ways to make such determinations without getting involved in rigorous examinations or extensive interviews. For example, postive testimonials from former students, National Bridge Federations, and/or well known players would be sufficient IMO to at least give teachers a chance to prove themselves.
I also agree with those of you who suggested that giving students the ability to rate their teachers and making this information public would be a good thing.
I also agree with those of you who said that we will never be able to stop "black market" teachers who choose not to be involved in this program. I doubt we would even try to do this. Instead we would try to offer teachers enough value that it would be worthwhile for them to participate. This in turn would make it hard for non-participants to compete for students.
By the way - one of Echognome's ideas will be part of the next version of the web-client: it will include a powerful hand generator, the ability to constrain all 4 hands, and you will be able to use this both at Partnership Bidding Tables (as usual) and at Teaching Tables as well. More good stuff coming - you will see it soon
