PARENTS have blasted teachers at a Manchester primary school who allowed their nine-year-old children to roam around a theme park "unsupervised."They say when they agreed to their youngsters going on the trip from St Clement's Primary they had expected them to be with an adult at all times.But when the group of 30 children returned home to Higher Openshaw they were horrified to learn the children had spent most of the day wandering around the Camelot theme park in pairs.Some of the youngsters - they said - had to ask strangers for the time, to make sure they did not miss the coach at the end of the day. Parents are so angry they have vowed to write to the local education authority."In light of everything that has happened in the last week - with Sarah Payne - we were flabbergasted that teaching staff could leave kids unsupervised," said Jimmy Short, whose nine-year-old daughter Kirsty was on the trip. "She won't be going on any more trips with the school, unless I can be given a 100 per cent guarantee she will be supervised at all times."Lisa Carmichael says she was horrified when her daughter Gabrielle told her how she had become separated from her pals after leaving a ride. She said: "This is unbelievable. If I had known she was left to roam around Camelot on her own I wouldn't have let her go." And anxious mum June Johnson was bemused when nine-year-old son Samuel told her about his day at the theme park. She said: "My son doesn't wear a watch and he had to approach strangers to ask what time it was. That undermines everything I have told him for the past nine years. The school has let me down."Ms Johnson says parents even asked if the school wanted volunteers to help with the trip, but instead they were told it was all in hand.Headteacher Vera Curtin - who was not in charge at the school when the trip was organised last year - has stood by the arrangements, but says they will be looked at following the complaints from parents.She said: "On arrival children were grouped with friends in order to give them independence and flexibility to make the most of the attractions. It was made quite clear to the pupils that they had to stay with their friends. As a minimum they were in pairs, so no-one was ever alone."One of the adults was in a central point, the others patrolled round through the day in case the children needed assistance. The teachers and adults were well experienced in the care of the children and wouldn't compromise their welfare in any way."My understanding is that, of the school visits that were there, this was a common method of supervision of the children. I understand that Camelot is extremely well staffed and has good security."There were a number of children who gained a lot of confidence and one child said it was the best day of his life. They certainly enjoyed it."
