We recognise that having your child assessed can be an anxious time for you. We actively involve you in the assessment process and we are always happy to answer any questions you may have. We offer six different types of assessments:

Developmental Assessments  

We offer a play-based developmental assessment comparing your child’s current skills with the skills typically displayed between birth and eight years of age using the Griffiths Mental Development Scales – Extended and Revised (GMDS-ER). This assessment includes gross motor and fine motor skills, communication skills, self-care skills, social skills and problem-solving skills. Developmental assessments are not an autism diagnostic assessment or an IQ test. The Griffiths assessment is often used with children who may be experiencing a developmental delay (for example in their speech, or gross motor skills) and can give useful information about whether the delay is specific to one area, or whether the child is experiencing a “global developmental delay” across more than one area. It can often be helpful when planning early interventions or transition to school. For more information, click here (Link to Developmental Assessment Info Pack)

Autism/Asperger’s Assessments 

During an autism diagnostic assessment, we like to get to know you and your child, how your child thinks and how they respond to situations. Best practice research suggests that a comprehensive autism assessment involves gathering information about a child’s communication, social skills, interests and behaviour across several settings. We like to collect information from the following sources:

  • A structured play observation session with your child using the Autism Diagnostic Observation Schedule (ADOS)
  • An in-depth interview with you about your child’s development and any concerns that you have, using the Autism Diagnostic Interview – Revised (ADI-R)
  • The Australian Scale for Asperger’s Syndrome (ASAS) questionnaire and an ASD Student Profile, both completed by your child’s school or preschool teacher

Cognitive Assessments  

Cognitive assessments can be helpful in identifying a child's or adolescent's strengths and areas where they need support to reach their full learning potential.  Cognitive assessments are often requested to support applications for assistance for your child at school, or to support an application for eligibility for a placement or service available to individuals functioning at a particular cognitive level.  Depending on the age of the child, we use one of two cognitive assessments:

The Wechsler Preschool and Primary Scale of Intelligence - Third Edition Australian (WPPSI-III) is designed to assess the cognitive abilities of children aged between two years, six months and seven years, three months.  It allows us to compare a child's verbal, perceptual, processing speed and overall cognitive ability with that of other children of the same age.  

The Wechsler Intelligence Scale for Children, Fourth Edition (WISC-IV) is designed to compare a child’s verbal comprehension, perceptual reasoning, working memory, and processing speed with that of other children of the same age. The WISC-IV is used to assess the cognitive abilities of children and adolescents aged between six years and sixteen years of age

Cognitive assessments require some “test-taking skills”, for example sitting at a desk, listening to a stranger (Lydia) and attempting to answer their questions, and copying what the stranger is doing. Some young children on the autism spectrum can have difficulty with these tasks and may be better able to show their skills in a more flexible developmental assessment. If you would like a cognitive assessment as part of an autism assessment or separately, please call Lydia Meem on 4967 3363 or email her at to discuss whether a cognitive assessment will meet your needs, or whether a developmental assessment would be more appropriate.

Attention Assessments  

The Conners 3 includes Parent and Teacher questionnaires designed to identify whether children display signs of hyperactivity, impulsiveness and/or other forms of inattention (daydreaming, easily distracted), behavioural difficulties, social difficulties, and learning difficulties. It may be a useful tool where children and adolescents are more active than their peers, or there appear to be gaps in a student’s knowledge and understanding. Many children with autism or Asperger’s have some repetitive behaviours, and may fidget or appear disorganised. However these behaviours may be less prominent in classrooms with a predictable routine and visual prompts to assist organisation and learning. An attention assessment can help to identify if students meet criteria for an attention difficulty in addition to their autism or Asperger’s. If you would like an attention assessment as part of an autism assessment or separately, please call Lydia Meem on4967 3363 or email her at For information about fees and services, please go to Fees and Services

Adaptive Assessments

The Adaptive Behaviour Assessment System - Second Edition (ABAS-II) is designed to assess daily functioning skills of individuals between birth and 89 years of age.  ABAS-II questionnaires can be completed by adult clients, parents/carers, or teachers.  These questionnaires are designed to capture how much assistance the client needs to engage in everyday tasks, including communication, social and leisure activities, academic or work tasks, and health and safety.  Adaptive assessments are sometimes requested by funding bodies to confirm that individuals with low scores on cognitive assessments experience an impairment in their independent living skills compared with other people their own age, and require support to reach their full potential.

Reading Assessments

We provide reading assessments for students from Kindergarten to Year 12.  Results of these assessments can be used to support applications for a reader (special provisions) for high school examinations through the Board of Studies.  The York Assessment of Reading for Comprehension Australian Edition (YARC, 2012) has reading passages designed specifically for Australian primary and secondary students.  The YARC Early Reading assessment also provides a breakdown of pre-reading skills for children who are not yet fluent in reading.  These early skills include Letter Sound Knowledge, Early Word Recognition, Sound Isolation and Sound Deletion.  The YARC provides standard scores, percentiles and age-equivalent scores so that students can be retested over time to monitor progress of reading intervention.

Mental Health Assessment of Adults with Intellectual Disabilities

We provide clinical consultations for adults with autism and/or intellectual disabilities where they and their carers can discuss issues which are affecting their home, work and community living.  We offer tailored behavioural strategies to suit particular behaviours and to fit in with current routines.  Depending on the issues raised, we may include an assessment of the client's mental health to see if this may be impacting on their current behaviour and lifestyle.  We may gather information from the client, carers and other service providers about any recent changes in the clients' sleep, appetite and skill levels compared with their usual abilities.  We use evidence-based tools including the Glasgow Depression Scale for People with a Learning Disability (GDS-LD) and the Glasgow Anxiety Scale for People with Intellectual Disability (GAS-ID).
