Mr Fom,
There have been a few previous posts on this forum discussing the pros and cons of a) The UK Operations Managers' Association course for ops officers, run at Bournemouth, and b) the FAA Dispatcher's Licence course (much more expensive) run at Dallas-Fort Worth. Try the search engine, or at worse display all topics and scroll through the titles. This should also bring up links to the agencies running the courses.
Good Luck!
