The Autism Speaks 100 Day Kit is a tool designed to help assist families of children recently diagnosed with autism during the critical period following an autism diagnosis. The kit includes basic information about autism and its symptoms, tips for dealing with a child's diagnosis, information about therapies and treatments, forms to help parents get organized, a comprehensive list of resources and more.

The 100 Day Kit was released in 2008 and a second version was released in 2011. It was created by the Autism Speaks Family Services staff in conjunction with both a professional and parent advisory committee and the Family Services Committee.
