Question 1

What is the winter weather tolerance threshold for schools in Illinois?

Accepted Answer

In Illinois, school districts typically trigger cancellations or 2-hour delays when snowfall reaches 5 inches or more, or when ice accumulation exceeds 0.1 inches. However, county districts and urban centers might adjust these parameters based on local road slope safety and plow resources.

Question 2

Who makes the official decision to close schools in Illinois?

Accepted Answer

Decisions are made at the local level by each school district's superintendent. Superintendents consult with local emergency management agencies, highway departments, and weather forecasters early in the morning (usually by 5:00 AM) to evaluate bus route safety before buses begin active pick-ups.

Question 3

Does extreme cold cause school closures in Illinois?

Accepted Answer

Yes. When temperatures or wind chill readings drop below -15°F, schools in Illinois frequently declare cold-weather closures. This is to protect children from frostbite while waiting at bus stops and to prevent vehicle mechanical failures.
