Who We Serve
We provide comprehensive autism testing and assessment services for children and adolescents from toddlerhood through age 21. Our specialized approach is designed to meet the unique developmental needs of each age group:
​
Toddlers and Preschoolers (16 months - 5 years): Early screening and assessment using age-appropriate diagnostic tools
School-Age Children (6-12 years): Comprehensive evaluation that considers academic and social functioning
Adolescents and Young Adults (13-21 years): Specialized assessment that addresses the complexities of teenage development and transition planning
Our school and clinical psychologists are experienced in working with this full age range, ensuring that your child receives developmentally appropriate assessment regardless of when you seek our services.

Understanding Autism Assessment and Diagnosis
Autism testing is a comprehensive process that goes far beyond simple checklists or single screening tools. Unlike medical conditions diagnosed through blood tests or other tests, autism spectrum disorder requires careful observation of your child's behavior, social communication patterns, and developmental history using evidence-based diagnostic tools.
Our autism assessment process examines several critical areas of your child's development:
Social Communication and Interaction: We observe how your child connects with other children and adults, their use of language skills, and their ability to engage in back-and-forth social communication. These patterns help our healthcare professionals understand your child's unique social interaction style within the autism spectrum.
Behavioral Patterns and Interests: Our evaluation includes assessment of repetitive patterns of behavior, intense interests, and sensory processing differences. We recognize that these characteristics often represent strengths and preferences rather than deficits.
Developmental History: Through detailed interviews with parents and other caregivers, we gather comprehensive information about your child's early milestones, current functioning, and any concerns that have emerged over time.
Functional Assessment: We evaluate how autism spectrum characteristics impact your child's daily life, including their success in school settings, relationships with other children, and family dynamics.

Why Early Detection Matters
Early identification of autism spectrum disorder can significantly impact your child's developmental trajectory. Research shows that children who receive appropriate early intervention services demonstrate better outcomes in social communication, adaptive behaviors, and overall quality of life.
​
The American Academy of Pediatrics recommends screening for autism at 18 and 24 months during routine visits with your child's pediatrician. However, many parents, particularly mothers who spend significant time observing their children's daily behaviors, often notice early signs even earlier. These parental observations are invaluable in the autism screening process.
​
Early autism diagnosis provides several crucial benefits:
-
Access to Services: Formal diagnosis opens doors to early intervention services, educational support, and therapeutic resources
-
Family Understanding: Understanding your child's behavior patterns reduces stress and helps create supportive home environments
-
Educational Planning: Early identification ensures appropriate accommodations from the beginning of your child's school experience
-
Sibling Support: When families understand autism spectrum characteristics, they can better support all family members

Our Comprehensive Autism Testing Services
At Think Happy Live Healthy, we utilize gold-standard diagnostic tools to ensure accurate and thorough autism assessment. Our comprehensive approach includes multiple screening tools and evaluation methods designed to capture a complete picture of your child's development.
Evidence-Based Screening Tools
Monteiro Interview Guidelines for Diagnosing the Autism Spectrum (MIGDAS): This comprehensive diagnostic tool provides structured guidelines for conducting thorough autism assessments. The MIGDAS offers a systematic approach to evaluating autism spectrum characteristics across different developmental levels and helps our psychologists gather detailed information about your child's social communication and behavioral patterns.
Autism Spectrum Rating Scales (ASRS): This evidence-based autism assessment tool evaluates autism spectrum behaviors across multiple settings and informants. The ASRS provides valuable insights into your child's functioning at home, school, and in community settings, allowing our team to understand how autism spectrum characteristics manifest in different environments.
Childhood Autism Rating Scale, Second Edition (CARS-2): This autism assessment tool provides quantitative measures of autism severity based on observable behaviors across different settings. The CARS-2 utilizes direct observation to help our school and clinical psychologists assess and classify the severity of autism spectrum disorder based on specific behavioral criteria, making it particularly useful for understanding your child's needs in school settings and interactions with other children.
Comprehensive Evaluation Process
Our formal evaluation process involves our specialized team of school and clinical psychologists, each bringing expertise to the autism diagnosis process for children and adolescents:
Developmental Assessment: Our team evaluates your child's overall development, including cognitive abilities, language skills, and adaptive functioning to understand how autism spectrum characteristics interact with other aspects of development.
Behavioral Observation: We observe your child's behavior across different activities and settings, paying particular attention to social communication patterns, repetitive behaviors, and sensory processing preferences.
Family Interview: Detailed discussions with parents and other caregivers provide essential insights into your child's development, daily functioning, and family concerns.
Medical History Review: We consider your child's complete medical history, including any previous evaluations, to ensure comprehensive understanding of their developmental profile.
