SENIOR pupils at a school in Glasgow have had their prom cancelled after some caused chaos on their leavers' day. 

A group of around 50 S6 pupils at Jordanhill behaved in a "deeply inappropriate and upsetting manner" last week.

In a letter sent to their parents and carers, it stated a number of objects were thrown onto a school walkway, including a full tin of beans. 

Numerous flares were let off, some thrown into the school. The group also left condoms on the grass, as well as a plastic bag which had been urinated into. 

A banner with a "deeply offensive" comment was put up in the school, and pornographic images were also brought in. These were attached to a fence, meanwhile, others were scattered around the school pitches. 

Jordanhill is the only mainstream school in Scotland directly funded by the Scottish Government and operates independently of local authority control.

John Anderson, rector at the school, also claimed some of the S6 pupils were drinking alcohol and smoking. 

In the letter, he wrote: "When staff went to challenge the group, they moved and stood on the roundabout at the entrance to the college grounds, chanting inappropriate songs, shouting into a megaphone, throwing eggs, drinking alcohol and smoking.

"Amidst this, several glass bottles were broken which added to a threatening atmosphere for any passers-by. Even though there was staff present telling pupils to disperse, this large group walked slowly down Southbrae Drive, and round to Chamberlain Road, continuing to act in this very disruptive manner.

"The situation was suitably threatening that a staff member called the police and reported the situation.

"Despite the repeated and very clear instruction to keep away from the school, the large group returned to the front entrance of the school and continued to throw eggs toward the school and display a large, obscene inflatable which was tied to a building in the school." 

Mr Anderson went on to say that it was believed the behaviour was clearly planned in advance, and a decision had been made to cancel the prom at Mar Hall. 

He wrote: "It was made clear to the entire S6 year group that the prom was conditional on a positive end-of-term celebration.

"Our decision, therefore, is partly to reinforce that actions have consequences but also that sadly we cannot trust pupils not to repeat these actions when they are gathered as a group.

"On a more practical level, the prom relies on staff volunteering to supervise and following S6 leavers’ day we have received indications that many staff are no longer willing to attend, which is entirely understandable given the disruption caused and lack of concern shown to staff." 

The school had previously taken time to talk with the S6 pupils about leavers' day concerns through an S6 assembly, regular meetings with the school captains, and an email to all S6 parents.

At the end of the letter, Mr Anderson wrote: "There has been an unhealthy culture of S6 end-of-term anti-social behaviour which we hoped had ceased with our efforts to educate the year group about the impact these activities have on others.

"As a school, we must now reflect on how we prepare our S6 leavers for the end of term and look towards breaking a cycle of unacceptable behaviour which has caused great upset in the community." 

A spokesperson for Jordanhill School said: "Our S6 leavers enjoyed a final assembly, celebrating their many achievements as a year group.

"Parents took part in the assembly as we wished pupils well for their exams and next steps beyond school.

"Sadly, a group of S6 pupils left the school and caused disruption in the local community. We wrote to all S6 pupils and parents detailing our concerns and our response.

"We will continue to work with our young people to promote positive relationships both in school and in the community."
