Shannon's response:
I can't really schedule one- they're done by NROI (National Range Officer Insitute- a part of USPSA). John Bent from OKC gun club had enough interest that he was able to schedule one here last Spring, but I don't think there are any plans to have another one any time soon. The last class had about 20 people in it- I'm not sure how many they require to schedule one but I can find out from John this weekend.
You can also sign up for any of the RO classes offered elsewhere- the list of upcoming classes is here:

Also, although I recommend that anyone who is interested take the class, you don't have to be an officially certified RO to RO or run the timer at the local matches, so if you guys aren't already, feel free to as long as you know the range commands and the roles of the RO (watching for safety issues, scoring etc.)
Thanks,
