The principal of the school is pending the investigation after a vision emerges that he is pulling a student by the hand.
The education minister called the recordings "terrible and worried".
At this stage, it is unclear when the vision is taken, but is believed to be recent.
James Merlino said the investigation will begin immediately and the director in question, at Manor Lakes College, will stand up while held.
The boy can be seen dragging himself through the school yard.
