A teacher who showed pupils how to cut themselves so they could paint in blood has been allowed to carry on teaching.
Sandra Kennedy, 54, admitted matters got out of hand during the lesson at Ringwood Waldorf School, Hampshire last year, when 13 pupils cut themselves.
The National College of Teaching and Leadership found her guilty of unacceptable professional conduct, but said it was an "isolated mistake".
She was suspended from the alternative education school and later resigned.
The part-time teacher had been teaching a Year Nine history of art lesson at the independently run school, when she demonstrated how to draw blood from the fingertips.
The school's senior management team administrator Nigel Revill said they would not re-employ Ms Kennedy.
"The teacher concerned had resigned during our internal disciplinary procedure, which was invoked when the incident came to light," he said.
"We were not involved in the hearing and we have no intention of reinstating the teacher. We hope this brings the matter to a close."
