A middle school French teacher on a field trip to Montreal found what appeared to be marijuana in one of her student's possession. As the school principal, you must determine the appropriate steps to take in response. This includes notifying the superintendent and police, identifying witnesses, respecting the student's rights, documenting the incident, and considering whether to send the student home early or impact on the rest of the trip. Key decisions involve balancing education, legal issues, and ensuring student and staff safety.
