How ADIT training works
You must register as a student with the Institute, for which you need a valid email address. Students should aim to be registered by 30 November if they wish to sit an examination the following June (and 31 May if they wish to sit an exam in December), although registration will remain possible up to the end of January for June exam candidates and the end of July for December exam candidates.
Then you must separately apply to sit the examination. The deadline for this is the end of February for the June examination and end of August for the December examinations.
