First Day of the 2022-23 School Year Message from the Superintendent
Posted 8/11/22

Dear Mt. Diablo Unified School District Families and Staff,
Welcome to the 2022-2023 academic year. I hope today was filled with excitement as we welcomed back students to our campuses. We are so fortunate to have the responsibility of educating your students this year. Please bookmark the MDUSD website as well as your student’s school website. A wealth of information is shared through the website as well as ParentSquare. 
Over the summer, many of our students moved out of the area and many moved in. Inevitably, we will need to adjust some of our class assignments for students and teachers. I know this can be daunting. The large majority of our students will not be impacted by these adjustments, but just in case it happens to your student, it will be OK!  
Although COVID-19 is still present in our school community, we are thrilled that our students will be physically in school engaging in deep learning activities. The guidelines continue to shift, just as they have for the past couple of years. That said, please see the protocols for when a positive test result is present. As always, our website has a wealth of information and resources on this topic. 
I wish you all the best as we embark on this exciting new year. 
Dr. Adam Clark
