But experts are concerned about the effectiveness of this technique as teachers are not being properly trained to pick up on extremist behavior, and are misreporting children.
A Year 12 Canberra student who was one week away from his exams was confronted by two Australian Federal Police officers for his essay about Muslim terrorists and western intervention.
The Muslim student had also travelled to the Horn of Africa to donate sporting equipment to children in need.
His teacher had informed police saying there was fear that he might be radicalized.
The teenager was questioned but was not charged. This left him scarred and affected his grades.
Dr Clarke Jones, a criminologist from the Australian National University said he read the Muslim student's essay and said there was nothing indicating that he was radicalized.
He said teachers are not trained well enough and lack the expertise to be able to identify whether or not students are at risk of being radicalized.
