Upcoming Events

Presidents Day and Second Winter Break — No School

No school for students or staff.

Arrival and Dismissal Reminders

The start and end of the school day are busy times at Challenger.  As a reminder, all students in grades 1-5 who walk to/from school will enter and exit through the front gate.  The back gate/loop is only for students who are being picked up in a car and our kindergarten students.  The only exception at the back gate is for students who walk through the field at Beaver Lake to get home. 

If you are utilizing the back loop to drop off or pick up for any student in grades K-5, keep the following in mind:

  • Students must exit the car from the passenger side of the car.
  • Parents may not park or get out of their car for any reason.  If your child needs assistance getting in/out of the car, you should park your car in the front lot and walk them in.  The back loop is only for students who can get in and out of the car independently.
  • Please pull your car up as far as possible while you are waiting.  Follow the directions of staff members.  Students are only allowed to enter cars in a designated area. 
  • You should have a placard placed on the dash with your child’s name and teacher’s name written to help us call students from their class line.
