It is important to note that while the DSM-5 TR provides specific criteria for diagnosing ASD, it is not always easy to diagnose. Clinicians must evaluate an individual's symptoms and behaviors against these criteria to determine if they meet the criteria for a diagnosis of ASD. To be diagnosed with ASD according to the DSM-5 TR criteria, an individual must exhibit symptoms from early childhood and these symptoms must significantly impair their daily functioning. These behaviors may include repetitive movements such as hand flapping or rocking back and forth, insistence on sameness in routines or rituals, or intense interests in specific topics. In addition to the social communication and interaction deficits, individuals with DSM-5 TR Autism must also display restricted, repetitive patterns of behavior, interests, or activities. This may include difficulty initiating or maintaining conversations, lack of interest in social interactions, or difficulties with nonverbal communication. In order to receive a diagnosis of DSM-5 TR Autism, an individual must exhibit persistent deficits in social communication and interaction across multiple contexts.

The DSM-5 TR provides a list of specific criteria that clinicians use to diagnose ASD.
