I would love to work for a children’s publishing company like scholastic, but I’m not sure what degree is needed for it. I mean, there isn’t a "book publishing" degree, you know? I was thinking of double majoring in elementary education and literature? Please help, especially if you work for one of these places please give advice!!

First, you need K-12 certification, and preferably classroom experience.

Then, it depends on what you would like to contribute, and on your talents. Writing and editing? Major in English and develop your writing skills.

Art? commercial illustration.

Knowledge of new media would be tremendous, combined with the K-12 certifiication.
