Autism Speaks has many great resources.  We really like their video glossary– this web-based tool is designed to help parents and professionals learn more about the early red flags and diagnostic features of autism spectrum disorders (ASD) by seeing side-by-side the subtle differences between typical and delayed development in young children (this does require creating a login, but it’s free).  The treatment section includes some of the more commonly used interventions for children on the autism spectrum: behavioral interventions, developmental interventions, structured teaching and supports, clinical therapies, and toddler treatment models.  We also like their great tool kits.

Autism Speaks is not without it’s controversies.  They have not fully discredited the myth that ASD is caused by vaccines and often talk about ASD in terms of treatment as if it was a disease to be cured.  Despite these limitations, Autism Speaks, has many great resources for families and professionals.
