Autism is a different way of experiencing and thinking about the world. Communicating in a non-autistic world (and classroom) can be difficult because it is fast, ambiguous and shifts between different people seemingly all at once. There are many social and communication rules that everyone else seems to know but the autistic child hasn't learned, and people are unpredictable and can't always be trusted to do what they say. Sensory messages can be overwhelming to an autistic child and some are sensory seeking because their sensory systems need the extra stimulation. Autistic children are also able to achieve many things and are capable of learning in our classrooms – if we provide the right understanding and support for them.
Sometimes all children's behaviour is confusing, unpredictable and challenging to us. All human beings have 'behaviour'. It's what we do. It's how we react, show how we feel and how we keep ourselves safe. Behaviour is also communication when we cannot find or use words.
