Margaretta Slingsby, 58, was an Italian teacher at Lismore Heights Public School in northern NSW.
In about March 2005 a nine-year-old student "B" threatened her: ''I'm going to get you, Slingsby slut.''
Ms Slingsby took time off from work to recover from the shock of the student's abuse.
Two months later, she saw "B" chasing a girl into the library, screaming, ''You f---ing slut, I'm going to get you.''
Ms Slingsby and the librarian restrained him, but the boy kicked them both and punched the librarian.
"B" was taken away by the principal but returned and again attacked Ms Slingsby.
''He came up behind me and tried to push me down the stairs,'' she said.
''He grabbed me by the hair and was dragging me.
I could feel my hair being ripped out of my scalp.''
The boy punched a female staff member who tried to intervene and threw rocks and dirt in Ms Slingsby's face.
Later, she said, she was sitting in the staffroom when B ''came tearing in'' with the principal in pursuit.
The boy ''grabbed me by the hair and he threw me down on the ground''.
"B" was involved in several other violent incidents at the school.
Ms Slingsby was depressed after the student's second attack.
She couldn't sleep.
She is now unable to teach and suffers from post-traumatic stress disorder.
She is suing the NSW Education Department for negligence.
Andrew Lidden, SC, is Margaretta Slingsby's barrister.
Andrew Lidden said that Lismore Heights Public School had more than its share of unruly children.
And that while the pupil involved - known for legal reasons as B - had a history of ''at times quite violent misbehaviour'', the school had no plans in place to manage his extreme behavioural problems.
Margaretta claims that the NSW Education Department was negligent in -
* failing to ascertain the student's history of violence and abuse,
* failing to suspend him after the March incident,
* and enrolling him in the school when it is not safe for his teachers or for the other students.
