The Wisconsin Early Autism Project’s research found out that:

• There is a significant average increase of 25 IQ points within the period of one year among children.

• There is a high percentage of over 70% of children in the research who learned to speak in phrases.

• Almost 50% of the children move into the average range on measures of adaptive skills and teacher’s rating of social skills:
  • These children show increases in IQ from an average of 55 at the beginning of treatment to 104 after 3-4 years of treatment
  • Their academic skills increase to the average range
  • They are able to succeed in regular classes without support
  • Most importantly, they have friends

• Many important skills are gained by those children who did not achieve IQ scores in the average range. Important skills gained are:
  • Cognitive skills increased from 16 to 44 months
  • Adaptive skills increased from 16 to 37 months
  • Language skills increased from less than 12 months to 27 months
  • Social skills increased from 10 to 31 months
  • At the end of the study, these children were continuing to gain skills at a rate of 3 to 4 months per year in expressive language and social skills.
