Understanding Autism Spectrum Disorder (ASD)
Autism Spectrum Disorder (ASD) is a neurodevelopmental condition that affects how individuals perceive, communicate, and interact with the world around them. The presentation of ASD varies widely, ranging from subtle social and behavioural differences to more pronounced challenges that can impact daily functioning. While signs often emerge in early childhood, many individuals may go undiagnosed until adolescence or adulthood.
According to a 2023 study by National University Hospital (NUH) and National University Polyclinics, autism was identified in 1.1% of 5,336 children aged 18 months. This means approximately 1 in 100 children were diagnosed with ASD.
At Care Alliance Counselling, we offer comprehensive autism assessments in Singapore to support both early intervention in children and diagnostic clarity for adults. Our goal is to provide timely, evidence-based evaluations that lead to greater understanding, appropriate support, and improved outcomes for individuals and their families.
Signs of Autism Spectrum Disorder
Autism presents differently in every individual, and its signs can vary widely depending on age, developmental stage, and level of support needs. Some individuals may show noticeable traits early in life, while others may develop more subtle signs that become clearer over time, often in school, social settings, or adulthood.
Recognising the signs of autism is the first step toward understanding and accessing appropriate support.
Social Communication and Interaction
-
May not respond when their name is called or may seem unresponsive at times
-
Prefer minimal physical contact and may avoid being cuddled, often choosing solitary play
-
Exhibit limited facial expressions and poor eye contact
-
Experience delayed speech development or may lose previously acquired language skills
-
Struggle to initiate or sustain conversations, often using speech only to request items or label objects
-
Speak in a monotone, singsong, or robotic voice
-
Repeat words or phrases (echolalia) without understanding their appropriate use
-
Appear to misunderstand simple questions or instructions
-
Show limited emotional expression and may not recognise others’ feelings
-
Rarely point at or show objects to share interest with others
-
May be passive, disruptive, or aggressive in social settings
-
Have difficulty interpreting body language, tone of voice, or facial expressions during interactions
Patterns of Behaviour and Interests
-
Repeating the same movements, such as rocking, spinning, or hand-flapping
-
Engaging in self-injurious behaviours like head-banging or biting
-
Insisting on specific routines or rituals, and becoming distressed with even minor changes
-
Exhibiting unusual gait or movement patterns, such as tiptoe walking or clumsiness
-
Using exaggerated or stiff body language
-
Becoming highly fixated on specific object features (e.g. spinning wheels) without engaging with the object as a whole
-
Displaying heightened sensitivity to sounds, lights, or textures—or a reduced response to pain or temperature
-
Avoiding pretend or imaginative play, and rarely imitating others’ actions
-
Demonstrating intense focus on specific objects or activities
-
Preferring a limited range of foods, often based on texture or appearance
Disclaimer: The presence of these signs does not confirm a diagnosis. A formal autism assessment is required to determine whether an individual is on the autism spectrum.
Autism Diagnosis & Early Intervention
In Singapore, autism tests involve the use of standardised, evidence-based assessment tools tailored to different age groups and needs. One commonly used tool is the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2). This structured, play-based assessment evaluates social interaction, communication, and behavioural patterns in children who may present with signs of autism.
To gain a deeper understanding of the individual's developmental background, the Autism Diagnostic Interview-Revised (ADI-R) is typically conducted with parents or caregivers. This structured interview gathers detailed insights into early childhood behaviours, developmental milestones, and current concerns.
For children, tools such as the Childhood Autism Rating Scale (CARS) and the Gilliam Autism Rating Scale (GARS) are used to assess signs based on both clinical observation and caregiver input.
But for adults, assessments may include the Autism Spectrum Quotient (AQ), Camouflaging Autistic Traits Questionnaire (CAT-Q), and the Comprehensive Autistic Trait Inventory (CATI). These tests help evaluate the presence and intensity of autistic traits, particularly in individuals who may have developed coping strategies that mask symptoms.
Together, these tools form the foundation for a comprehensive assessment process that not only confirms or rules out autism but also informs the creation of a personalised intervention plan.
Autism Assessment at Care Alliance Counselling Singapore
We provide a structured and compassionate approach to autism testing in Singapore for both children and adults. Our assessment process includes several key phases to ensure a thorough evaluation:
Initial Evaluation
The process begins with an in-depth consultation with parents or caregivers. During this session, we gather detailed information about the individual’s developmental history, behaviours, strengths, and specific concerns. This collaborative approach allows us to build a holistic picture of their unique profile.
Detailed Report
Once autism testing is complete, our team compiles a detailed report that highlights the individual’s strengths, areas of difficulty, and key observations. It serves as an essential resource for healthcare professionals to support an informed diagnosis, and for families or individuals to better understand the assessment outcomes.
Autism Testing
We use a combination of standardised autism assessment tools, tailored to the individual’s age and developmental level. These tools evaluate a range of areas, including communication, social interaction, emotional regulation, sensory responses, and cognitive abilities. Rest assured that our therapists prioritise comfort and dignity throughout the process to ensure a supportive experience.
Feedback Session
To conclude the process, we conduct a dedicated feedback session with the individual or, where appropriate, their parent or guardian. During this session, we walk through the findings, answer any questions, and offer tailored recommendations. Whether it's exploring mental health counselling in Singapore, accessing school-based support, or navigating life after an adult autism diagnosis, our team is here to guide you at every step.
The autism assessment process is carefully tailored to suit both children and adults. While the methods differ slightly depending on age, both assessments aim to build a comprehensive understanding of the individual’s developmental and behavioural patterns.
Children Autism Assessments
When assessing a child for autism, the evaluation team takes a holistic and collaborative approach to understand their developmental profile. This may include:
Developmental History Review
Behavioural Observation
Review of External Reports
Medical Review and Physical Evaluation
Parents or caregivers are asked about the child’s developmental milestones, such as when they began talking, walking, or displaying social behaviours. This helps us understand the child’s early development in context.
The child’s interactions, play, communication, and emotional responses are observed in a comfortable setting to assess behaviours commonly associated with autism.
Any documents or feedback from the child’s GP, preschool, or school are reviewed to gather insights into their learning, social, or behavioural patterns across different environments.
The child’s medical history is assessed to rule out any related conditions, and a brief physical examination may be conducted if needed.
Autism Assessment for Adults
Adult autism assessments focus on current traits as well as developmental history, helping uncover patterns that may have gone unrecognised earlier in life. The process generally includes:
​Self-Report Questionnaires
Developmental History Interview
Review of GP and Medical Reports
You may be asked to complete standardised questionnaires that explore social communication, sensory sensitivity, repetitive behaviours, and other autistic traits.
Where possible, we may speak with someone who knew you as a child, such as a parent, sibling, or long-time caregiver, to gather information about your early development and behaviours.
Any relevant medical history or mental health records provided by your GP will be evaluated to ensure a comprehensive understanding of your background.

Frequently Asked Questions About Autism Test in Singapore
How much is the cost of a private autism assessment?
Costs can vary depending on the complexity of the case and the type of assessment tools used. Please contact our team for a detailed quotation.
How long does it take to diagnose autism?
Autism assessments typically require 1 or more sessions to gather comprehensive information through interviews, observations, and standardised assessments. Once the evaluation is complete, the findings are reviewed by a qualified healthcare professional to make an informed diagnosis. The duration may vary depending on the individual’s age, complexity of symptoms, and the assessment tools used.
Is it worth getting an autism test as an adult?
Absolutely. Receiving an autism diagnosis in adulthood can offer meaningful self-understanding, validation of lifelong experiences, and potentially improved access to tailored mental health support. It could also help in gaining workplace accommodations and community resources.
What assessment tools do you use to diagnose autism?
In Singapore, autism assessments involve the use of standardised tools tailored by age group.
For children, assessments like the ADOS-2, ADI-R, CARS, and GARS evaluate communication, behaviour, and developmental history.
For adults, tools such as the Autism Spectrum Quotient (AQ), CAT-Q, and CATI help identify autistic traits, especially when symptoms are masked.
These tools ensure an appropriate diagnosis, helping healthcare professionals and care teams develop informed, individualised support plans.
At what age should I bring my child for an autism diagnosis?
Children as young as 18 months can be screened. However, formal diagnosis is generally more reliable from age 2 onwards.
