How can you volunteer to become an SGL (or is it DA select)? If you can volunteer, what are some ways to do so besides ASK?

I was the ALC Senior SGL for the 25W CMF at the Cyber Center of Excellence NCO Academy. At our NCOA, we instituted an application process in which you go to the school's website, download the packet and email it in directly. From there the Deputy Commandant would review your credentials (NCOERs, ERB, etc.), and set up a phone interview if you met the professional requirements. Different NCOAs have different processes, but if you are truly interested, I recommend you reach out to the NCOA directly.

Many times for BLC, you can go interview at the Academy. I taught BLC for 2 years and thats how I got SGL. ALC and SLC are a little different, usually require orders. Depending on where you want to instruct, i would contact your branch manager.

Do you have a NCOA on you post?
