Connecticut law requires that public schools be in session for at least 180 days per school year. 

School cancellations for weather or other emergency circumstances will extend the last day of school up to ten days. School closings in excess of ten days will be made up during the Spring Recess starting with Monday and working toward Friday.

Region 15 will post any unscheduled delays/cancellations at the top of the District and school websites, on Region 15's Social Media sites (e.g. Facebook page, Twitter), via SchoolMessenger notifications and through local and regional radio / television stations.  Delay and cancellation information can be found here
