How do you ensure accuracy in your autism evaluations?

Choosing a board-certified specialist to conduct your child’s autism evaluation will give you the comfort of knowing you are in expert hands—and that your child’s diagnosis is accurate. (Written by Dr. Chuck M. Ng.)

I am dual-board certified in Developmental-Behavioral Pediatrics and General Pediatrics. I had the privilege of training at a nationally recognized children’s hospital in New York. My clinical experience includes several years of practice in pediatric medicine within Kaiser Permanente, a national leader in healthcare delivery. My years of experience have given me the tools needed to ensure accuracy in every evaluation I make.

What are your observations based upon?

I rely on the use of standardized and validate measures to ensure an assessment is accurate. This involves multiple components:

  • Rating scales completed by parents to screen for various behaviors.
  • A structured interview with parents that returns a score based on the patient’s clinical history.
  • An observation of how the child plays. I will also guide parents through a series of activities in order to see their child’s responses.
  • If the child is over 4 years old, I would also perform IQ testing if the child is able to sit and participate.

These components provide me various interactions which I then use to complete a standardized evaluation tool specific for Autism. I arrive at my diagnosis based on the combination of these different tools, the patient’s clinical history, and my own interactions with the child. After the evaluation, each parent is provided a comprehensive report listing the results of these assessment tools so they can request services for their child through their medical insurance.
