Inclement Weather

During periods of inclement weather or in emergency situations, our first priority is the safety and welfare of our students and staff. At the same time, the closing of school can be burdensome to families due to childcare and work schedules.

We consider any change to our normal protocol, to be an exception and we place a strong emphasis on keeping our schools open. Some of the primary factors that are considered when making a decision include:

  • Safety and well-being of students and staff
  • Severity of the weather (extreme cold, flooding, etc.)
  • Timing of the weather event
  • Ability of buses and cars to travel safely
  • Operable condition of our buildings

The decision to cancel school or delay the start of school as a result of weather conditions, will typically be made before 6 a.m. This allows conditions to be monitored overnight to avoid unnecessary closures or delays. Decisions will only be made the night before if conditions are certain and warrant closure or a delay. 

In instances when the temperature is severe, but weather conditions are normal, the district will implement our Severe Cold Plan. We encourage families to establish contingency plans for possible closures throughout the school year regardless of the season.

When the decision to cancel or close a school occurs, the district may choose one of two options.

  • Implement an e-Learning Day, where students will participate in asynchronous activities.
  • Implement a traditional emergency day that will be made up at the end of the school year. 

Making the Decision

The Board of Education gives the superintendent the authority under Board of Education Policy 3050: Emergency Closings to determine the closure of a campus or the entire district, use of e-Learning Day or dismissal of school before normal dismissal time

Any decision for a weather-related closure is made in collaboration with area superintendents, local municipalities, the district’s bus service provider and, if necessary, the Illinois Department of Transportation. 

The district works collaboratively with feeder elementary districts 27, 28, 30, 31 and 34 on school closings and will keep them informed on late arrival or early dismissal actions. It is our goal to make decisions with the needs of families in mind. There are times, however, when Glenbrook High School District 225 may need to make a decision based on the existing conditions.

Whenever a decision is made to cancel school or alter the school day, it is based on the general safety conditions for all students and staff. The district recognizes that conditions may vary for each individual student or family. If you feel that it is unsafe to send your student to school, please contact the school attendance office and the student will be given an excused absence.

The district uses the National Weather Service (NWS) as the primary meteorological source to determine and declare weather conditions such as snow forecasts, wind-chill advisories or wind-chill warnings.


Communication of Decision

In the event of a weather-related or emergency closing, the district will use the following communication methods:

  • District Website –
  • Building Social Media Accounts
  • District Mass Notification System
  • WGN’s Emergency Closings website,
  • Mass media including major radio and TV sources

It is important for families to ensure their contact information is up to date. To review the contact information on file with the district, log into your PowerSchool Account and select the verification icon for the current school year. If you need to make changes to the contact information, please complete the parent/guardian and emergency contact update request form.

e-Learning Day

When a day is converted to an e-Learning Day, students will be given asynchronous assignments to complete during the e-Learning Day allowing them the flexibility to demonstrate their learning on their own timelines. Specifically:

  • Class assignments will be posted to Google classroom by 9 a.m., giving students the flexibility to complete assignments in any order and at whatever pace is appropriate for them during the day.
  • Teachers are available to assist students between 9 a.m. and 3 p.m.
  • Students will have until the next in-person meeting with their teacher to complete work that is assigned during the asynchronous e-Learning Day.
  • Student attendance on the asynchronous e-Learning Day will count as a regularly sanctioned attendance day for all students who complete the Google Form for each class.

Depending on the situation, the district may decide to implement a traditional emergency day that will be made up at the end of the school year.
