The No Outsiders programme was created in 2014 by Andrew Moffat, the assistant head teacher at Parkfield Community School in Birmingham.
The programme aims to teach children about the characteristics protected by the Equality Act – such as sexual orientation and religion.
Books used in programme include stories about a dog that doesn’t feel like it fits in, two male penguins that raise a chick together and a boy who likes to dress up like a mermaid.
But some parents at Parkfield Community School in Birmingham say lessons featuring books depicting same-sex relationships are not age-appropriate and the lessons have currently been put on hold.
