I am putting the bulk of the information contained in this guidebook in checklist, chart, and reproducible, fill-in-the blank form so that they can be copied and consumed as needed. Many other informational pamphlets are written in narrative form, such as chapters and paragraphs, which is not conducive to being able to use and consume information in daily life situations. I had always wanted a comprehensive handy guidebook of reference-type information and consumable charts and forms but was never able to find one. So I have taken the opportunity to compile such a guidebook. This handbook will give you assistance and general information regarding itinerant home and community special education at the early intervention level. I've included a section of common occurrences and situations and lists of community services, resources, related programs, and phone/contact information. Anyone who is involved with a child with ASD—whether as teacher, therapist, parent, or other family member—can benefit from this guide, and you are welcome to copy and use all templates provided as needed.
