Further to your enquiry ref the FAA Dispatch School.
I personally would recommend the Airline Flight Dispatcher Training Center (AFDTC) at Hurst, Texas (KDFW).

I obtained my FAA Disp Lic their as well along wz El Jefe and Saiip.
The World Aircraft Dispatcher School not too sure about that particular school I think it is a new one recently opened - on the other hand the AFDTC is the most popular by far in the Dallas area.
As far as schools in Tucson - Heard they have a very poor pass mark and they give FAA Licences away easily without having to work for them.
