questioning

I need someone to help me briefly answer a few questions listed below. 

1. what are some concepts to look for, in a classroom, when evaluating children's pragmatic skills?

2. how much do individual difference, family background, or non-age-related factors influence a child's pragmatic development.

3. Do you personally know someone with autism? what is their biggest obstacle?

Do you think more people speaking out about their life with autism can help get a better understanding on how ASD affects pragmatics, and how can this help early childhood educators support children with ASD in the classroom?
