The safety of our students and staff is a top priority. Practicing various drills is a critical step in ensuring our students are able to react quickly in the case of an actual emergency.
On August 16, 2021, Governor Pritzker signed House Bill 2400, establishing new requirements for lockdown drills in schools. One of these requirements includes advance notification of a lockdown drill to all students, staff, and parents, as well as the opportunity for parents to exempt their child from participating in a schoolwide exercise.
If you would like additional information on drill requirements for schools, more information can be found in the Illinois Safety Drill Act.

Please contact Mr. Lane Linder, Director of Safety and Security,  if you have any questions about the Lockdown/Evacuation procedures or would like to exempt your child(ren) from participating. An alternative process will be offered in these situations.

Lake Forest School District 67 and Lake Forest Community High School District 115 practice Integrated Pest Management, a program that combines preventative techniques, non-chemical pest control methods, and the appropriate use of pesticides with a preference for products that are least harmful to human health and the environment. The term “pesticide” includes insecticides, herbicides, rodenticides, and fungicides.

The School Districts maintain a registry of people who wish to be notified prior to pesticide applications. To be included in this registry, please contact Daniel Mortensen, Director of Buildings and Grounds,, and you will be notified prior to the use of pesticides. Please specify if you want to be contacted by phone or email.

BrightArrow Instructions



District 115’s first priority is the safety of our students, staff, and parents. The decision to close our schools, or adjust our start or dismissal times for an emergency-related situation is a complicated one and based on a number of factors.

Although the District uses the following sources to guide the decision, the Superintendent and District Administrators will make the final call to close school.

  • NOAA National Weather Service (NWA) updates and Wind Chill report.
  • Local weather forecast services.
  • Local law enforcement and city agencies.
  • Reports from our bus company.
  • Reports from our Buildings/Grounds staff.
  • Conversations with neighboring school district administrators.

Road conditions and the possibility of dangerously unsafe temperatures are the main factors that drive the decision. If we need to close or delay the start of school, parents will be notified using our BrightArrow Notification System and through postings on our website.

For winter weather health and safety information, visit the CDC website.


Wind Chill Warning

Schools will be closed under the condition of a WIND CHILL WARNING. A wind chill warning indicates that life-threatening conditions and a risk to safety exists. Measures should be taken to safeguard life and property immediately. A wind chill warning is typically issued when the wind chill will be -30°F or colder OR the actual air temperature is -15°F or less.

Severe Cold School Closure: Wind Chill Warning

  • Classes will be cancelled and school closure protocols will be instituted.
  • All notification systems will be leveraged to send school cancellation communications to families.
  • Extracurricular activities will be suspended while the wind chill warning is in effect.

Wind Chill Advisory

A WIND CHILL ADVISORY is issued when conditions do not meet the wind chill warning criteria but still cause significant inconvenience. The weather during a wind chill advisory is not life threatening but presents conditions that may result in inconveniences or pose moderate risk to safety. A wind chill advisory is typically issued when the wind chill is -20°F to -29°F OR the actual air temperature is -5°F to -14°F.

Severe Cold Action: Wind Chill Advisory

  • Schools will be open and student attendance is expected.
  • Extracurricular activities will be evaluated and may be suspended if conditions persist.
  • All outdoor student activities will be suspended.
  • Any evacuation drills scheduled will be cancelled and rescheduled to a more weather-appropriate day.

The National Weather Service will be the meteorological source to determine and declare a wind chill warning or wind chill advisory.
