Signs and Symptoms of Autism Spectrum Disorders
One of the most popular autism checklists used by pediatricians is called the
M-CHAT (MODIFIED CHECKLIST FOR AUTISM IN TODDLERS) You can take this test online when your child is between 16-30 months. Take the test, print it out and bring it to your child’s Pediatrician.

However The Autism Treatment Evaluation Checklist (ATEC) was developed by Bernard Rimland and Stephen M. Edelson of the Autism Research Institute to help determine if children are benefiting from a specific treatment. They provide sub scale scores as well as a total score to be used for comparison at a later date to monitor how well your child is doing over time. The lower the score, the fewer the problems. Compare baseline ATEC scores with post-treatment ATEC scores.
