Understanding Autism can open the door to meaningful support, self-awareness, and thriving. At Coast Psychology in Oyster Bay, Long Island, we offer comprehensive Autism evaluations for children, teens, and adults.
Our assessments are designed to provide clear, evidence-based insights into each individual’s social communication, sensory experiences, adaptive functioning, and learning profile. Every evaluation is conducted exclusively by a licensed psychologist, ensuring clinical accuracy, individualized care, and detailed recommendations that meet both clinical and state documentation requirements.
Expert Autism Evaluations by Compassionate Licensed Psychologists
At Coast Psychology, all testing is performed by licensed clinical psychologists with advanced training in neuropsychological and developmental assessment. We never use pre-licensed clinicians, trainees, or technicians.
Our approach integrates gold-standard Autism assessment tools with a neuroaffirming and strengths-based perspective—helping families and individuals understand the full picture of abilities, needs, and supports.
We use a comprehensive battery of research-backed instruments tailored to each person’s age and presentation, which may include:
ADOS-2 (Autism Diagnostic Observation Schedule, Second Edition): A semi-structured, play- and conversation-based assessment widely regarded as the gold standard in Autism diagnosis.
ADI-R (Autism Diagnostic Interview–Revised): A detailed caregiver interview exploring developmental history and social-communication patterns.
Vineland Adaptive Behavior Scales, Third Edition (Vineland-3): Measures daily living, socialization, and communication skills.
MIGDAS (Monteiro Interview Guidelines for Diagnosing Autism Spectrum): A structured, conversational tool emphasizing sensory and interpersonal experiences in a strength-based way.
Additional Cognitive, Executive Functioning, and Social-Emotional Assessments as needed to provide a full understanding of strengths and areas of support.
Our evaluations are also fully compliant with OPWDD (New York State Office for People With Developmental Disabilities) requirements for diagnostic confirmation and adaptive functioning documentation.

Our Autism evaluations are individualized to meet the needs of:
Children: Identifying early developmental or social-communication differences to guide school supports and interventions.
Teens: Clarifying symptoms as social and academic demands increase; understanding how Autism presents during adolescence.
Adults: For those seeking diagnostic clarity, workplace accommodations, or OPWDD eligibility—especially individuals who may not have been evaluated in childhood.
We recognize that Autism presents uniquely across genders, ages, and neurotypes, and we tailor our assessments accordingly.
