Any chance of getting into Drill Sergeant school with a type 1 morality waiver from when I joined the military?

Depending on the infraction, waivers are considered, and potentially approved, by the TRADOC or USAREC commander, depending on which direction you go. For both, there's a lot of scrutiny on morality waivers but I know tons of people (pre-2013 ALARACT) who were able to go either direction with entry-level waivers. Call Drill Branch and ask the question or check out http://www.jackson.army.mil and find the DS Academy link for contact info.

Getting in to Drill Sergeant School is a hard task and only the ones with clean records are selected or are allowed to volunteer. I served as a Drill Sergeant from 1989 to 1991 and I am sure that the standards are still the same today. The Drill Sergeant Corps prides itself on high morale, discipline, and values which the Drill Sergeant must live by. When selecting a candidate, they are going to look for soldiers with no morality issues in the past. If you came in with a morality waiver, it is going to be a problem getting into Drill Sergeant School, no matter what you have done in your career thus far. You may have to call your Congressman and get him involved in your selection process to see if he can find out how to get you selected. I had to go to Korea and apply while there to be able to get selected, coming off of a hardship tour. I had a clean slate and had a hard time getting it. Good luck in your selection.

Speak to military lawyer. They will know more about that than I do. Good luck.
