Blessed Trinity have teamed up with the police to deliver a programme on Knifecrime Prevention, funded by the Home Office.
Police have facilitated the funding and the school have got £10,000 to help to deliver the programme, focusing on training pupils to act responsibly if they know someone has a knife.
They had their first session with PCSO Beccy Walker and Paul Goodall, a former Police Inspector who is the Knife Crime Prevention Investigator for the East Division.
Teacher Mrs Nolan said: "As well as educating pupils, every member of staff will be taught to spot the signs of gangs and know the best way to tackle incidents with knives.
"External agencies will be coming into school over the next year to deliver sessions to everyone."
Paul said: "It's about prevention of knife crime and knowing what to do if someone has a knife. It's just raising awareness."
Pupil Oliver said after the first session: "I have learnt how knife crime can affect everyone, family and friends and it can have far reaching consequences."
