Superintendent Rundle Message On MISD Updated Emergency & Reunification Preparation Guide

We appreciate our community’s flexibility this week as we dealt with a two-hour delay for schools on Wednesday. Hopefully the worst of the winter weather is behind us, but if it is not we are prepared. And speaking of emergency preparation and communication, I thought it would be a great opportunity to revisit some of the tools, resources, and things families can access and do to help keep our schools safe and supportive for everyone.

Superintendent Fred Rundle

I struggled with this month’s message- starting, stopping, and deleting many drafts. Toiling with what to say seems odd given the many student, staff, and district accomplishments in 2023. I’m proud of what we accomplished in November alone. However, I am also keenly aware of that which continues to challenge us near and far.

Welcome Back To School Message From Superintendent Rundle
