Autism is typically diagnosed by a multidisciplinary team of qualified professionals rather than a single individual. This team often includes:

• Developmental Pediatricians: These medical doctors specialize in child growth, assess developmental milestones, and rule out other potential conditions.
• Child Psychologists: These specialists evaluate behaviors and social interactions using standardized testing tools such as the ADOS-2.
• Neurologists: They focus on brain-related factors and identify any neurological comorbidities, such as seizures.
• Child Psychiatrists: These professionals also conduct formal evaluations to identify the disorder.

In some cases, the diagnostic team may also involve speech-language pathologists and occupational therapists to provide a comprehensive view of a child’s communication and sensory needs. While no single medical test exists for autism, these experts collaborate by combining behavioral observations, parental interviews, and developmental history to reach a formal diagnosis based on DSM-5 or ICD-11 criteria.
