ASD Assessments

The Hummingbird Centre offers a variety of Educational and Developmental Assessments. Please contact us for a quote or for further information about our assessments.

Please note that Mental Health Care Plans cannot be used towards Assessments.

Autism Assessments

Our psychologists are trained in the assessment and diagnosis of Autism Spectrum Disorder using the gold standard assessment tools such as the Autism Diagnostic Interview - Revised (ADI-R) and Autism Diagnostic Observation Schedule (ADOS-II).

The ADI-R is a structured interview used for formal diagnosis and is sensitive to distinguishing Autism from other developmental disorders. The ADI-R takes approximately 1.5-2.5 hours to complete with a clinician and can be used to assess both children and adults.

The ADOS-II is a systematic observation tool involving play and social activities, relevant to the child or adult’s age, functioning and language level. The purpose of the ADOS-II is to observe the individual’s social and communication behaviours which are key elements to consider in a comprehensive evaluation. The ADOS-II takes approximately 1 hour to complete.

The purpose of a diagnostic evaluation is to discover whether someone has any symptoms of Autism, how many symptoms they have and how those symptoms impact the individual’s ability to fully interact with their environment. As there are no medical tests that can diagnose Autism, the clinician focuses on behaviours observed by parents/carers, teachers and others in the child’s life, as well as understanding the individual’s development and obtaining information from the above-mentioned assessments.

A comprehensive Autism assessment involves 3 to 4 sessions across approximately 6 weeks.

Attention Deficit Hyperactive Disorder Assessments

Our psychologists are trained in the assessment of Attention Deficit Hyperactive Disorder (ADHD).

When evaluating someone for ADHD, it is typical to engage in multiple stages of assessment prior to formal diagnoses. Assessment will usually involve comprehensive evaluation of information from several sources including parents/carers, family members and teachers.

Typically, a range of health professionals are involved in the formal diagnosis process including a paediatrician and/or psychiatrist. Our clinicians can help connect you with other professionals in the community.

The assessment process will vary depending on individual circumstances and presenting problems. However, our clinician’s may typically use the Conners Comprehensive Behaviour Rating Scales (CBRS) or the Conners 3 questionnaires to screen for ADHD. The CBRS assesses a multitude of disorders, behaviours, emotions and academic problems affecting children and adolescents (between 6 years and 18 years) and can be completed by a range of people in the young person’s life and sometimes by the young person themselves. The Conners 3 is more specific to symptoms of ADHD and its most common comorbid problems and disorders in children and adolescents.

The Behaviour Rating Inventory of Executive Function (BRIEF) may also be used in this assessment. The BRIEF questionnaire assesses a person’s executive functioning i.e., working memory, self-control and flexible thinking across school/work and home environments.

A Cognitive assessment, such as the Weschler Intelligence Scale for Children 5th Edition (WISC-V) may also be used to identify strengths and weaknesses, as well as potential learning difficulties. See Cognitive Assessments below for further information.

Behavioural Assessments

Our clinicians are able to administer a range of behavioural assessments to support parents/carers and teachers to better understand the function and best management strategies for challenging behaviours. Behavioural assessments can identify behaviour patterns, potential reasons for the behaviour and can help explain how someone interacts with the world around them.

There are several assessments that can assist in identifying and managing behavioural concerns, and a few of these tests are listed below. Your clinician will identify which assessments are most pertinent to your presenting problems.

Conners Comprehensive Behaviour Rating Scales (CBRS) - The CBRS assesses a multitude of disorders, behaviours, emotions, and academic problems affecting children and adolescents (between 6 years and 18 years) and can be completed by a range of people in the young person’s life, and sometimes by the young person themselves.

Achenbach Child Behaviour Checklist (CBCL) – The CBCL is a checklist for parents/carers and teachers to complete to detect emotional and behavioural problems in children and adolescents.  The CBCL assesses internalising behaviours (i.e., anxious/depressed) and externalising behaviours (i.e., aggression and rule breaking). It also looks at symptoms consistent with diagnostic categories.

Cognitive and Adaptive Assessments

Our psychologists are trained in the assessment of Cognitive ability using current standardised Cognitive and Adaptive Behaviour Assessments.  Cognitive assessments help to identify strengths, weaknesses and learning difficulties. They assist in developing learning strategies and recommendations as well as assisting in examinations of giftedness, specific learning disabilities, intellectual disability, Autism and Attention Deficit Hyperactivity Disorder. The following are examples of cognitive assessments that our clinicians can administer:

Weschler Adult Intelligence Scale - 4th Edition (WAIS-IV) – The WAIS-IV is the most advanced measure of cognitive ability for young adults/adults aged 16 years to 90 years 11 months. The four main indices the WAIS-IV measures includes Verbal Comprehension (an individual’s ability to listen to a question, draw upon learned information and reason through an answer), Perceptual Reasoning (an individual’s ability to examine a problem, organise their thoughts and create solutions), Working Memory (the ability to memorise new information, hold it in short term memory and manipulate it to produce results) and Processing Speed (the ability to focus attention and quickly discriminate and sequentially order visual information.

Weschler Intelligence Scale for Children 5th Edition (WISC-V) – The WISC-V is the child and adolescent version of the WAIS-V for children aged 6 years to 16 years 11 months. Like the WAIS-IV, the WISC-V also measures Verbal Comprehension, Working Memory and Processing Speed. It also assesses Fluid Reasoning (using reasoning to identify and apply rules) and Visual Spatial (evaluating visual spatial relationships).

Weschler Preschool and Primary Scale of Intelligence 4th Edition (WPPSI-IV) – The WPPSI-IV measures cognitive development for children aged 2 years and 6 months to 7 years and 7 months. Administration time takes 45-60 minutes depending on the age of the child. Similarly, to the WAIS-IV and WISC-V, the WPPSI measures progress in areas such as how to think and problem solve, thinking processes and decision-making skills.

The WAIS-IV, WISC-V and WPPSI-IV produce a full-scale Intelligence Quotient (IQ) score which your clinician will interpret in terms of general intellectual functioning and discuss with you in the full context of the assessment, clinical interview and observation.

Adaptive assessments are useful in assessing skills of daily living across the lifespan and are vital in generating a holistic understanding of the individual’s cognitive and adaptive functioning. The Adaptive Behaviour Assessment System – 3rd Edition (ABAS-III) is a rating scale typically used by our clinicians in conjunction with a cognitive assessment, however, the ABAS-III is also useful as a stand-alone assessment for individuals aged 0-89yrs. The ABAS-III can be self-rated by an adult or filled out by a parent/carer and a teacher. This assessment covers three broad domains: conceptual, social and practical and the rater is required to indicate how frequently the individual performs each activity within that domain. Your clinician will help interpret the results in the context of how effectively and independently the individual is able to focus on everyday activities required to function and meet environmental demands.  

Learning Assessments

Our psychologists are trained in the assessment of children’s learning ability, providing insight into a person’s learning needs.

An example of a learning assessment is the Weschler Individual Achievement Test 3rd Edition (WIAT-III). The WIAT-III can be administered to people aged 4 years through to 50 years, 11 months and administration time can take up to 90 minutes. The WIAT-III can identify academic strengths and weakness, assist in informing decisions regarding eligibility for educational services or diagnosis of a specific learning disability. The WIAT-III also advises objectives for interventions.

Typically, our learning assessments are completed alongside a cognitive assessment, such as the Weschler Intelligence Scale for Children 5th Edition (WISC-V) to further assist in the assessment of strengths, weaknesses and specific learning needs.

Trauma-Informed Psychological Wellbeing Assessment

The Hummingbird Centre provides Trauma-Informed Psychological Wellbeing Assessments for people of all ages who have been exposed to trauma.

This assessment is informed by the Neurosequential Model of Therapeutics (NMT) and contains a complete developmental history and collated information from a wide range of sources. An NMT certified clinician will use this information to complete a NMT report including a functional brain map which provides a visual representation of the persons needs and strengths.

The assessment process helps to identify domains of functioning that are either under-developed or dysfunctional which in turn helps guide the selection and sequencing of developmentally sensitive and neurobiologically guided interventions. These assessments assist families and services by prescribing therapeutic interventions which can be implemented throughout the persons day and across various settings.
