Parent Message: October 29, 2021

Dear Parents,

Northbrook School District 27 has been advised by the Cook County Department of Public Health to quarantine all students in another third-grade classroom at Shabonee School out of an abundance of caution. If you have not already been contacted by the District, your child is not required to quarantine. Students in that classroom were picked up rather than riding the bus. 

We will shift to a remote learning environment for this classroom only, beginning today, with a return-to-school date of Thursday, November 11. The remainder of our classrooms will stay open for in-person instruction.

The CDC and Illinois Department of Public Health define an outbreak as:

1. Multiple cases comprising at least 10% of students, teachers, or staff within a core group; or 2. At least 3 cases within a core group that:
- meet the criteria for probable or confirmed school-associated COVID-19 cases with symptoms onset or positive test results within 14 days of each other;
- are not identified as close contacts of each other in another setting (i.e. household) or outside of the school setting; and
- are epidemiologically linked in the school setting or school-sanctioned extracurricular activity

This classroom will undergo cleaning and disinfection in accordance with CDC guidelines. We ask all families to continue to monitor their children for symptoms and to keep their students home when ill.

The CCDPH reassures us that school is one of the safest places to be given our safety protocols that are in place. Further, the SHIELD testing done at Shabonee today will allow us to identify any additional cases. Testing will continue twice weekly at Shabonee for 28 days, and weekly testing will soon be up and running District-wide. We will continue to monitor cases and update the District’s COVID-19 Dashboard

We encourage our community to keep COVID safety in mind outside of the school setting. We must work together to keep our schools safe. 

Thank you for your partnership.


John Deiter, Ph.D.
Superintendent of Schools
