One of the best ways to get hired as a controller (outside the military), is through a CTI training school. There are only a handful of them right now (UND, Purdue, Embry-Riddle, MNATCTC, Beaver College, etc...). Most of these program's have a 100% placement rate upon completion of training.
I will be going through the program as soon as I complete my Master's at UNOmaha, probably at UND.
