I have read through the Air Force thread and don't recall if you already addressed the details of the 2 year AEGD.
How many openings are there every year? 10. As far as I know we already have 10 for next year's class.
In the past, how competitive has it been? Recently it has been getting more and more competitive. As mentioned earlier, I think we are full next year and have already filled some slots for the following year.
What are the differences between the 1 and 2 year AEGD? 1-year AEGD is less didactic than the 2 year. The 2 year is more demanding clinically and is preparing you to take the ABGD board exams.
Would completing the 2 year AEGD make it more likely that you would be stationed OCONUS or being deployed or both? Not necessarily more vulnerable for OCONUS assignments, but you are more deployable.
Would competing the 2 year AEGD (compared to AEGD 1) make you a more competitive applicant to other Air Force residencies like Endo or Perio? Yes. Keep in mind that the AF considers it a specialty program, so typically you must serve 5-years in a specialty before you can apply to another one. You can get a waiver for that, its not guaranteed and is easier to get if you are applying to a specialty where we are undermanned.
Thanks for your continued insight AFDDS.
