The best source of information for DAU courses is the DAU iCatalog. Certification requirements are reviewed and approved annually by the OSD Functional Area Leader. As courses are updated, the predecessor courses are generally accepted for a two-year period of time, however, that timeframe may vary and longer or shorter acceptance periods for course predecessors are determined on a course by course basis.
Be sure to check the DAU iCatalog for more information: https://icatalog.dau.edu/.
