Thousands of students from storm damaged schools began attending class in different school buildings Wednesday, but getting them there is proving to be a bit of a challenge.

Department of Education officials promised shuttle buses to take the roughly 20,000 students from their old schools to the new ones, though NY1 is told there are only enough buses to pick up half of them.

In some cases, NY1 is told displaced students were between one and two hours late Wednesday and that attendance was expected to be low.

Parents whose children can't get to a bus are being told to report to the substitute school where they will be given MetroCards. However, some parents dropping off kids at PS 246 in Flatbush say they were not given the cards.

With several schools still being used as shelters and more than a dozen still without power, schools are trying to make the best of it.

"It's not going to be easy. I'm not going to paint a rosey picture at all. It's going to be very difficult - especially with a nor'easter coming, for these children in dislocated schools to get to theses schools," said Schools Chancellor Dennis Walcott.

Students at schools without power will be relocated tomorrow and parents who take their kids to school on their own will be reimbursed for travel.
