What is the difference between an autism screening and a diagnostic evaluation?

A screening is a brief set of questions that can indicate if a child is at risk for ASD. A comprehensive diagnostic evaluation is a much more in-depth process required to make a formal diagnosis, involving clinical interviews, standardized assessments like the ADOS-2, and integration of information from multiple sources.

What happens after an autism diagnosis?

A diagnosis unlocks deeper understanding and provides access to a wide range of supports, therapies, and educational accommodations designed to help autistic individuals thrive. It is a new beginning that opens doors to appropriate services and resources.

Is a school-based autism diagnosis sufficient?

A school-based educational classification of autism determines eligibility for school services. A formal medical diagnosis from a licensed clinical psychologist is often required to access medical and community-based services and supports outside of the school system.

Can adults be diagnosed with autism?

Yes. Many adults seek evaluation after recognizing autistic traits in their own children or struggling for years with social difficulties without understanding why. Women in particular may have learned to mask or camouflage autistic traits, leading to late-in-life diagnosis.

What is the ADOS-2 assessment?

The Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) is a gold-standard, semi-structured assessment that provides opportunities to observe social communication, interaction, and play skills in a standardized way. It is a crucial component of comprehensive autism evaluation.

Understanding Autism Spectrum Disorder (ASD)

Autism Spectrum Disorder (ICD-10 code F84.0) is a neurodevelopmental condition characterized by differences in social communication, sensory processing, and behavioral patterns. The term "spectrum" reflects the wide variation in how autism presents – from individuals who need substantial support in daily life to those who live independently and may not be diagnosed until adulthood.

Modern understanding recognizes autism as a neurological variation rather than something that needs to be "cured." Our approach focuses on identifying strengths, understanding challenges, and developing strategies that honor neurodiversity while supporting areas where assistance is needed.

Core Characteristics We Assess

During our comprehensive psychological testing process, we evaluate:

Social Communication Differences: Challenges with nonverbal communication, maintaining relationships, or understanding social nuances
Restricted Interests: Deep, focused interests that may seem intense to others
Repetitive Behaviors: Stimming, routines, or rituals that provide comfort or regulation
Sensory Sensitivities: Over or under-responsiveness to sensory input like lights, sounds, textures, or movement
Executive Functioning: Challenges with planning, organization, or adapting to changes
Cognitive Profile: Often uneven abilities with areas of significant strength alongside challenges

Autism Across the Lifespan

Early Childhood (Ages 2-6)

Early identification allows for timely intervention when the developing brain is most adaptable. Signs we evaluate include:

Limited eye contact or social smiling
Delayed or atypical language development
Lack of pretend play or imagination
Intense reactions to sensory experiences
Preference for parallel play over interactive play

School Age (Ages 7-12)

As academic and social demands increase, previously masked traits may become apparent:

Difficulty with peer relationships despite desire for friends
Literal interpretation of language
Challenges with group work or unstructured time
Intense special interests that dominate conversations
Meltdowns when routines are disrupted

Adolescence (Ages 13-18)

The complexity of teenage social dynamics can highlight autism-related challenges:

Difficulty navigating complex social hierarchies
Challenges with abstract thinking in certain areas
Increased anxiety or depression as awareness of differences grows
Masking behaviors that lead to exhaustion
Difficulty with executive functioning demands of high school

Adults

Many adults seek diagnosis after years of feeling "different" without understanding why:

History of social difficulties or misunderstandings
Challenges maintaining employment despite capabilities
Relationship difficulties, including in marriage
Sensory issues that impact daily life
Previous misdiagnosis of anxiety, depression, or other conditions
Recognition after a child's diagnosis ("That sounds like me")

Our Gold-Standard Assessment Process

Accurate autism diagnosis requires comprehensive evaluation by experienced professionals. Our psychological testing process uses multiple assessment methods to ensure accurate diagnosis:

1. Clinical Interview

We begin with an in-depth developmental history, exploring early milestones, current functioning, and specific concerns. For children, we interview parents; for adults, we may include family members who knew you as a child.

2. Standardized Testing

We use gold-standard assessment tools including:

ADOS-2 (Autism Diagnostic Observation Schedule): The gold standard for autism assessment
ADI-R (Autism Diagnostic Interview-Revised): Comprehensive developmental interview
Cognitive Testing: To understand intellectual abilities and learning profile
Adaptive Functioning Scales: To assess daily living skills
Executive Functioning Measures: To evaluate planning and organization
Language Assessment: When communication concerns are present

3. Behavioral Observation

We observe social interaction, communication patterns, play or leisure activities, and responses to environmental changes during structured and unstructured activities.

4. Comprehensive Report

You'll receive a detailed report including:

Clear diagnostic conclusions with ICD-10 coding (F84.0)
Comprehensive strengths and challenges profile
Specific recommendations for support and intervention
Educational or workplace accommodation suggestions
Resources for continued learning and support

Autism in Girls and Women: Often Overlooked

Autism often presents differently in females, leading to underdiagnosis or misdiagnosis. Our psychologists are trained to recognize these differences:

Better Masking Abilities: Girls often learn to camouflage autistic traits through imitation
Different Special Interests: May focus on socially acceptable topics like animals or fiction
Internalizing vs. Externalizing: More likely to experience anxiety or depression rather than behavioral issues
Social Motivation: Often have strong desire for friendship despite social challenges
Later Diagnosis: Frequently not identified until adolescence or adulthood

Common Co-Occurring Conditions

Autism often occurs alongside other conditions, which our comprehensive assessment can identify:

ADHD: Up to 50% of individuals with autism also have ADHD
Anxiety Disorders: Particularly common in adolescents and adults
Depression: Often develops in response to social challenges
Learning Differences: Including dyslexia, dyscalculia, or dysgraphia
Intellectual Disability: Present in approximately 30% of cases
Giftedness/2e: Many autistic individuals are twice-exceptional
Sensory Processing Disorder: Affects majority of autistic individuals
Sleep Disorders: Common due to sensory and regulation challenges

Frequently Asked Questions About Autism Testing

At what age can autism be diagnosed?

Autism can be reliably diagnosed as early as 18-24 months, though many individuals aren't diagnosed until later in childhood or even adulthood. There's no "too late" for diagnosis – we evaluate individuals across the lifespan.

How long does autism testing take?

Comprehensive autism evaluation typically requires 4-6 hours of direct testing, often completed over multiple sessions. This includes clinical interviews, standardized testing, and observation. You'll receive a detailed report within 2-3 weeks.

Is autism testing covered by insurance?

Many insurance plans cover autism diagnostic testing when medically necessary. We provide detailed invoices with appropriate CPT codes for insurance reimbursement. Our staff can help you understand your benefits.

What's the difference between autism and Asperger's?

Asperger's syndrome is no longer a separate diagnosis. Since 2013, it's been included under Autism Spectrum Disorder (ICD-10 F84.0). Individuals previously diagnosed with Asperger's would now receive an autism diagnosis, often with a notation of "without intellectual impairment."

Can adults be accurately diagnosed with autism?

Yes! While autism is a lifelong condition present from birth, many adults are diagnosed later in life. Adult diagnosis requires specialized assessment approaches, which our psychologists are trained to provide.
