Zoey 101 (2005)

Pacific Coast Academy, an all boys boarding school is accepting female students for the first time since the school was established. Zoey's (Jamie Lynn Spears) little brother Dustin (Paul Butcher) is currently a student there. Zoey decides to be one of the first girls to become a student at PCA. This is very exciting, but also very scary. Fitting in at a new school is hard enough, but going away to boarding school and living on your own when you're only thirteen can get a little crazy, especially when the girls are heavily outnumbered by the boys...
