  • Intensive workshop training may be as effective as intensive clinic based treatment, but drop-outs and problems with treatment maybe more common.
  • Groups getting TEACCH or eclectic treatment may not do as well.
  • 15% normal range Weshler after 1 YR of treatment (1/2 verbal, 1/2 non-verbal)
  • 30% normal range after 2 YR of treatment on same test
