Petition Educate all Teachers about disability ADHD, Autism, Asperger's

Why is it acceptable to allow teachers to teach our children with disabilities who have no understanding or knowledge of these conditions? Too many Teachers are being allowed to teach our children in our schools today, who have disabilities, such as ADHD, Autism, Asperger’s, teachers have very little or no understanding or knowledge of these conditions? We as parents wouldn’t think it was acceptable for our children to be taught English or Maths in our schools by unqualified Teachers who had no knowledge or understanding of these subjects. So why is it acceptable for a teacher to teach a child with disabilities who have no understanding, knowledge or training on the above diagnosis?
Educate and Train all Teachers/LSA and SEN in School throughout England about ADHD, Autism, Asperger’s so Teachers have a better understand so they are aware of their disabilities and the diffculties these children face. Stop Discrimination against our children in schools.
