What is the “ADX” test?

‘ADX’ stands for Aircraft Dispatcher. This is a standardized 80-question, multiple choice examination taken at an authorized  testing center (such as Sheffield School). A passing score of at least 70% is required – this would meet one of the prerequisites for passing an FAA-approved Aircraft Dispatcher course. Other prerequisites are required.
