Early Childhood/Special Education programs are mandated and funded by the federal government - NOT the state, so if you are talking about early childhood special ed. (ECSE) nothing going on in the State of IL will effect any budgetary issues/constraints.
On the bus - ECSE has the kids taking the bus so they learn one more "routine". Delays are often indicators of other developmental issues, so they learn one more "how to" at an early age. The ECSE bus is smaller, and has a second person helping the students in route. ("Typical" school busses have a lot more kids, and only have a driver--no aid.) So there are many benefits. I have never heard of them not coming house to house (for EC). I would call the school and ask about what options you have.
We live 3 blocks from the school, and they came to our house (just for the routine). I would do occasional pick-ups (which meant me walking my 3 kids a few blocks) but I wanted him used to the bus routine.
Good Luck - EC is awesome - every child should be so lucky to get it!!!
