Call the school, the transportation office doesn't return phone calls. When my son was in pre-k, the transportation office insisted that I didn't live on a public road that it was a private road because they hadn't finished building the houses in the neighborhood. I informed them that I'd seen buses in here in the Spring before and that the county had been maintaining the road here. They got all huffy and said they'd check into it and call me back. They never did.
I was all prepared to drive him to school everyday, but the day before school started, the pre-k bus driver called me herself. She didn't know anything about my call to transportation, she just knew that she had my son on her list and wanted to make sure she got the right house.
I have since found out that the school secretary is the godess of all things bus related
She has every bus stop and every child memorized within the first week of school.
