Looking for a picture book about a girl going to witch school. Maybe her first day? Something about riding a broom? Cover was dark purple or blue with stars and girl doing lots of different things. Read to me no later than 1994. Would have been a book nook title for K-3 age kids.
Could it be The Worst Witch by Jill Murphy? It was the first in a series, kind of like Harry Potter before there was Harry Potter. The first book was published in 1974, and I think it’s been released with covers in different styles, some of which did have stars on them.

Another possibility might be Lulu Goes to Witch School, but the cover doesn’t look like what you’ve described. Although, maybe it was also printed with a different cover that I haven’t seen.

Maybe one of Deborah Hautzig’s ‘Little Witch’ books?
Nattie Witch by ???
Or maybe Lulu Goes to Witch School by O’Connor. (there was an original version in the 80s, and it’s been reillustrated within the last five years)
Could it be Dorrie and the Haunted Schoolhouse, published 1992?
