Noticed in my local (Boston MA area) IEEE newsletter: a class offering, "Technical Writing for Technical Professionals".  This is not "how to be a tech writer", but is intended to help working engineers, scientists, and other techies improve their writing of technical documents.  Great idea, if it reaches even a few of the people who need it, the world will be a better place.

If this, or something similar, has been offered before, I haven't noticed it.  I've waded through a lot of really poorly written technical prose over the years, so I'm all for it.  A distressing number of my various developer colleagues seem to have believed that if they knew how to program, they didn't need to know how to write - and some of my tester colleagues seem to have believed that no one else was ever going to try to make sense of their test documents, so they didn't need to bother with writing stuff other people could read.  Some of the worst offenders were native speakers of English. 

A few years ago, I taught an in-house class for a previous employer that covered some of this type of thing - it was focused on reviewing specifications, but that's just the flip side of writing them.  No way of knowing if it helped much, unfortunately, as my class pretty much coincided with the beginning of the "let's move real development work away from this campus" thing for that employer, and the numbers of specs being produced dropped off a lot.
