Why can't Guardsmen become Drill Sergeants?

You can

We have National Guard drill sergeants here in MA. But our state also has a Recruit Sustainment Program (RSP), where new soldiers drill until they ship out to boot camp or are assigned to their new unit. There’s actually a lot of states that do this so I’m confused where all these other answers are coming from lol. We’ve had Nationa Guard Drill Sergeants for at least the last 15 years.

National Guard Drill Seargents perform their duties in the RSP program (Recruit Sustaiment Program) so yes you can become a drill sergeant in the national guard now I haven’t heard of any of them doing so in a BCT drill sergeant role

I am in the National Guard and just got selected to go Drill Sergeant school in North Carolina for nine weeks. So it is possible.

As a former Army Reserve Drill Sergeant and a Current 1SG of a Reserve Drill Sergeant Company who has worked a lot with my local National Guard units, here is what I know. National Guard Recruiters are sometimes allowed to go to Drill Sergeant School. However when they get back home they wear their campaign hat one weekend a month when they run a pre-basic program for area NG recruits. They are not allowed to, or at least some of my friends who did this job were not allowed by their commands to go to a Basic Training installation and push new trainees. That being said, as others have already stated, if you want to become a Drill Sergeant you should join the Reserves or go on Active Duty and request Drill Sergeant School as a contingent of re-enlisting.

The ARNG does have Drill Sergeants and NCO's are welcome to submit a package. Each state and territory (54) has an RSP program and is authorized several Drill Sergeants. The larger the state size (Guard size) the larger the allocation of Drill Sergeant positions. Additionally several Recruiters become Drill Sergeants.

I was in from 1988 to 2005 and I knew plenty of Guardsmen that were Drill Sergeants. Do they not allow them this anymore?
