Frequently Asked Questions
How Do You Decide When To Close Schools?
The decision to close is based on many factors.
- Building conditions: Do the buildings have power, light and heat?
- Site conditions: Is the parking lot plowed? Can buses get in and turn around, can parents drop off students and are the exit doors free of snow?
- Bus operations: Can the bus drivers get to the bus company? Do the buses start and do the drivers feel comfortable driving?
- Road conditions: Are the roads continually plowed and is traffic moving?
- Air temperature: How cold is it? Are the temperature and wind chill bearable? (See additional info, below.)
If the answer is yes to all of these questions, most likely the decision will be to keep schools open.
Extremely Cold Temperatures
There are times when schools may need to be closed due to dangerously cold temperatures. In these situations, wind chill is also taken into account, as well as the extent to which the temperatures are sustained throughout the school day. District 99 has collaborated with the other associated school districts to develop consistent standards. We will likely close school based on conditions when frostbite may occur after approximately 20 minutes of exposure during the times students are travelling to or from school. District 99 will use weather information from the National Weather Service when making these decisions. Please refer to the District 99 Wind Chill Chart for additional information.
Who Makes The Decision And Where Do You Get Your Information?
The superintendent of schools makes the decision to close the schools. The superintendent consults with some or all of the following: area superintendents, associated feeder school superintendents, the bus company and the police departments.
When Do You Make The Decision To Close A School?
The decision to close the schools is usually made very early in the morning, before 6 a.m., unless we learn of severe weather conditions headed this way. That way teachers and students getting an early start to school can be informed.
It's not an easy decision and one that has an impact not only on teachers and students, but families and working parents. If schools are closed, another day of attendance is added to the school calendar, which can affect the graduation schedule, senior exams and vacations.
