Sister Philip Hanrahan, of St Michael's Primary School in Belfast established a support group in her school four years ago to help children facing bereavement and other difficulties in their families.

It takes time for children to talk about events such as Omagh bomb, says Sister Philip

Trained as a counsellor, Sister Philip launched the support group after children were "traumatised" after getting caught up in the attempted murder of a taxi driver outside the school.

"We have children who have been bereaved as a result of the Troubles and all you can do is be there for them," said Sister Philip, accepting the award at a ceremony in London.

In the wake of the Omagh bomb attack this summer, Sister Philip said that "there was terrible sadness and shock. I think it takes time for children to talk about things. It will come out at different times".

Pupils at St Michael's endorsed the award for their teacher

The winning teacher was on a shortlist of eight finalists, including a teacher who had taken a party of students on a polar expedition and a teacher who had set up a radio station in his primary school.

Sister Philip, who will receive a £8,000 bursary for her school, was praised by the parent who nominated her for the award.

"She pre-empts what people need and then rolls up her sleeves and goes to the heart of their problem," said Edna Mullan.

"She is an inspiring teacher who is always happiest in the classroom surrounded by the children, who love her. She has time for everyone but never herself," said headteacher Sister Vincent Duggan

Nominations for 2,000 teachers were submitted, mostly by pupils, in this Disney-organised award. Each of the finalists will receive £2,000 for their schools.
