* Calendar Update
As of April 16, 2026, MSD has used seven inclement weather days. The MSD Board of Trustees voted to waive two of those days, resulting in five remaining school days that must be made up. As a result, the last day of school for students is now Thursday, June 11, and Friday, June 12 will be the last day for staff. Thursday, June 4 will now be a full day of school. Please note that this remains subject to change if additional inclement weather days are needed.
