I write in response to Dr Roger Lock's letter (TES, February 17).
I take issue with his view that animal welfarerights groups do not produce materials that are balanced.
The materials produced by the Royal Society for the Prevention of Cruelty to Animals' education department aim to raise awareness of animal welfare issues and to encourage responsibility for all living things through open discussion and debate.
Through our nationwide work with schools and teacher training colleges we know that teachers value and use well-balanced material that provides their students with the information necessary to make educationally sound, informed decisions and judgments for themselves.
Our materials obviously represent the RSPCA's policies, but they also reflect young people's interests and concerns, as well as being closely linked to the national curriculum, as recognised in the TES articles "Creature comforts" (February 3) and "Animal passions" (February 24).
