SPRINGFIELD, Mass. (WWLP) – Elementary school students from across the state will return to the classroom on Monday, if they haven’t already.

Springfield officials are letting parents know what to expect, including possible delays. The school district warns of potential bus delays in pickup and drop-off times.

“First Student” provides bus services for the district and they’re dealing with an unanticipated shortage of bus drivers.

“We were very surprised to learn of this issue and we trust First Student is working feverishly to address it. Our biggest regret is the inconvenience this creates for our families and we will continue to communicate with families so they will know what to expect throughout the week,” said Warwick. “Needless to say, we are monitoring the issue very closely.”

Springfield School Superintendent Daniel Warwick said parents are getting robocalls to inform them of the situation.
