Many of us were members of the Theocratic Ministry School for many years. Some say it helped them with public speaking, and maybe it did for some.
But, when you look back at the quality of student it turned out, was it really any good ?
Most Elders are crap Public Speakers, most R&F Bros are crap at reading aloud, most JW's are crap at selling their religion at the door, most JW's have scant real knowledge of the Bible.
There are reasons for this, quite often the TMS overeer hasn't a clue how to teach a person to progress. Often not having the necessary skills himself.
How can you teach what you do not know ?
Also the role playing done in the sister's talks bears no resemblance to a real conversation in the DtoD work, so nobody in the audience, or the sisters themselves, benefit.
All in all, the TMS is an epic fail.
