There isn't an official company policy regarding internal promotions. It is all at the discretion of your SD and DSD.
At our store, most of our TLs (including myself) were promoted internally. For ETL, it is essentially the same but we don't have a ton of ETL turnover. For both roles, they prefer not to promote from within the same department (for example, a style TM couldn't be a SS TL and a SS TL couldn't internally move to a SS ETL).
In terms of ETL they've gone off the rails lately and hired one ETL from outside Target. It lit a dumpster fire that has been going on entirely too long. The effects would be comical if my department weren't directly hit by it. 🫠 They'd have been better off promoting a TL from within the same department even. What a mess.
