Coed y Garreg Primary School was a primary school in Cardiff. Jasmine Pierce attended it and Kate was a teacher.
One day upon school closing time, the paedophile Mark Goodson waited outside the school in his car, looking for young girls to abduct and molest. He followed Jasmine Pierce in his car from the school, when he realised no one had come to pick her up (as her mother's boyfriend Roy had neglected to arrive on time).
Later, Fairies caused a freak wind storm on the school grounds to protect Jasmine from bullies, leaving many children terrified and traumatised, and causing much damage to the playground and surrounding trees. After this incident, the staff sent all the children home. Jack Harkness and Gwen Cooper spoke to Kate in the school, where they realised that Jasmine was the Chosen One. (TV: Small Worlds)
