Violence Threat Risk Assessment Protocol (VTRA)

The Upper Grand District School Board is committed to providing safe learning environments for all students, staff, school visitors, and community members. When a student behaves inappropriately, principals use progressive discipline to help a student take responsibility for their actions, change their behaviour, and learn from their mistakes. When safety is threatened by the potentially violent or dangerous behaviour of a student, which places either the student or others at risk, school staff follow specific protocols for the protection of all. It is important that you and your children are aware of these protocols. For more information, visit the board's website.
