Most schools want 2 LoR’s from academic subject teachers. That was emphasized at a number of the info sessions and my S’s school even regulated it. Many colleges (though not all) will allow an optional third rec from someone else (plus your counselor gets to submit one). My S was torn between the head of drama, head of band and the person who runs the community service and peer tutoring programs since he was strong with all of those. Your drama teacher could be this optional rec but doesn’t supplant one of your academic ones. Note in my S’s case they used Naviance to electronically manage the two academic recs but kids were forced to selectively manage (school-by-school) their optional recs separately through Common App (or whatever a school not on common app used).
