Shared services contracts are permitted under the law. A shared service may exist when a neighboring school district has the need to send pupils to the same nonpublic school as another school district. Thus school district B may contract with school district A to pay for their pupils to ride the bus that school district A owns and operates to transport their pupils to the same nonpublic school. Shared services may only exist when one of the school districts is actually providing the services.
A shared services agreement does not exist when school district B requests school district A to add a bus/child/route to an existing contract that school district A has with a pupil transportation services contractor. That would be considered “piggybacking”, which is not permissible under the law. School district B did not bid the services and has no legal authority to accept services from the contractor. They may not enter into a contract with school district A to permit their pupils to ride the contractor bus and make payment to school district A to cover the expense.
The key is who is providing the services, a neighboring school district or a contractor? The first is shared services, the latter is piggybacking.
