There was a movie that aired on the disney channel I'm guessing either mid or late 90s. All I can remember is the very end. There was a classroom of kids all standing and one girl was picked from the rest and she got to fly with a teacher I believe. I also remember a big sheet type thing or maybe it was the guys cape? Any help on this would be appreciated.

That's "The worst witch" I've got that on tape!

"Growing up, isn't easy. Wish the time would hurry by. Will I ever learn to flyyyyyy! Growing up isn't easy, does't anyone know why...."

The Worst Witch (1986) (TV)

least I'm 99.9% sure lol ^^ as that guy's cape was huge.

"Matilda" had a similar scene in it. Her father was played by Danny Divito. Her parents ended up giving up parental rights to her and her teacher adopted her. It was a comedy. Matilda had special powers and was very intelligient. Could this have been the movie you are asking about? :)
