According to the American Academy of Child & Adolescent Psychiatry, “Autism is a neurodevelopmental condition which is usually diagnosed in the first 3 years of life. Generally, parents become concerned when their child has delays in speech development, limited social relatedness, and restricted interests and activities.”

According to the American Academy of Child & Adolescent Psychiatry, “Parents and relatives should be concerned about their infant or toddler if they notice any of the following delays or behavior problems and discuss concerns with their child’s pediatrician to obtain appropriate referrals for evaluation:

• Lack of or delay in development of spoken language
• Repetitive use of language and/or motor mannerisms (e.g., hand-flapping, twirling objects)
• Little or no eye contact
• Lack of interest in peer relationships
• Lack of spontaneous or make-believe play
• Persistent fixation on parts of objects

Should your child’s pediatrician mention that social or language milestones are unmet during a routine checkup, or:

• If your child avoids making eye contact or frequently does not engage visually with others
• If your child becomes easily upset or startled by loud sounds or other sensory stimuli
• If your child faces challenges in communicating
• If your child shows little interest in social interactions
• If your child exhibits behavioral issues that lack an obvious cause
• If your child struggles to adapt to changes or unexpected events

Our licensed clinicians have over 100 years of ASD evaluation experience. In 2025, AT4K completed more than 1,100 autism assessments with a 100% payor acceptance rate.

AT4K provides comprehensive autism evaluations for children aged 7 years old and younger. We will consider evaluating a child aged 8 to 12 years old if we can meet their needs in our evaluation process. Our assessment only considers autism. We do not evaluate ADHD, learning issues, emotional / behavioral disorders, or other diagnoses outside of autism.

Diagnostic assessments are often a crucial first step in the journey of autism therapy. Many, but not all, insurance plans cover the cost of autism testing. Allow us to help verify your insurance coverage.

AT4K requires credit card authorization to be on file to address any patient responsibility following the completion of each appointment (insurance copay / deductible). Patient statements will be sent for review prior to any credit card charges.

In-person ASD assessments are conducted in Dallas / Fort Worth, Houston, and Denver. Additionally, we provide virtual ASD evaluations nationwide.

We provide virtual ASD assessments nationwide for families willing to self-pay, out-of-pocket. AT4K’s virtual evaluations use the same trusted, evidenced-based tools, process, and leading technology for which we have become known.

An ADOS-2 evaluation is between one-and-a-half and two hours long depending on the child’s specific needs. When we schedule your child’s evaluation, we will provide a more accurate estimate.

We do not provide medication management.
