ASD children in classroom

Children are diagnosed with autism based on the assessment that they are not developing as expected on three levels - social interaction, communication and repetitive or restricted behaviour. At school the behaviour of an ASD child may include the following:
- insistence on sameness; resistance to change - transitions, supply teachers, new faces etc.
- trouble reading social cues from others - not understand that the others do not want to talk about the same subject etc. or stand too close to them while lining up
- difficulty in expressing needs; uses gestures or pointing instead of words
- laughing hard or too loudly, crying, showing distress for reasons not apparent to others
- tantrums
- some may cover their ears when the school bell rings, others may bang on things seeking sensory feedback
- unresponsive to normal teaching methods
- over-sensitivity or under-sensitivity to pain
- no real fears of danger or unrealistic fears of typical events
- physical over-activity or under-activity
- unstable gross/fine motor skills
- not always responsive to verbal cues
Adults like teachers and, if the child has one, an EA, interacting with them at school would need to have a few strategies handy to deal with these situations in order to have the best possible educational scenario for the ASD child attending school.
