Psychological Assessments

We have years of experience using a diverse range of psychometric tests with a wide variety of clients. Tests most commonly used in our practice include (but are not limited to):

1. Wechsler Adult Intelligence Scale (WAIS-IV) is the most advanced measure of adult intellectual ability.

2. Wechsler Intelligence Scale for Children (WISC-V) is the new gold-standard assessment tool designed to measure a child’s intellectual ability.

3. Wechsler Individual Achievement Test (WIAT-IV) is an individually administered measure of oral language, reading, written language and mathematics.

4. Wechsler Memory Scale (WMS-IV) is  a neuropsychological test designed to measure different memory functions in a person. 

5. Woodcock-Johnson IV Tests of Cognitive Abilities (WJ-IV COG) is an individually administered, norm-referenced instrument that measures general intellectual ability and specific cognitive abilities in people aged 2 to 90+. 

6. Conners 4 Assessments assess ADHD and evaluate problem behaviour in children and adolescents.

7. Child Behaviour Check Lists (CBCL) is a widely used questionnaire to assess behavioural and emotional problems, including ADHD, ODD, anxiety and depression. 

8. Monteiro Interview Guidelines for Diagnosing Autism Spectrum (MIGDAS-2) provides evaluators with an efficient method of systematically gathering and organising the information needed to diagnose autism spectrum disorder (ASD) in children, adolescents, and adults. 

9. Gilliam Autism Rating Scale (GARS-3) assists teachers, parents, and clinicians in identifying autism in individuals and estimating its severity.

10. Autism Diagnostic Observation Schedule (ADOS-2) allows clinicians to accurately assess and diagnose autism spectrum disorders (ASDs) across age, developmental level, and language skills. 

11. Personality Assessment Inventory (PAI) assesses psychopathological syndromes and provides information relevant for clinical diagnosis, treatment planning, and screening for psychopathology. 

12. Vineland Adaptive Behavior Scales, Third Edition is the leading instrument for supporting the diagnosis of intellectual and developmental disabilities. Addresses the needs of individuals with intellectual and developmental disabilities, autism spectrum disorder, and ADHD.

Each psychometric assessment requires 2 to 3 hours of testing onsite with a clinician.

Formal assessment tools such as WAIS-IV and WISC-V require considerable testing, score interpretation, report preparation, and interviews.

Dune Health and Wellbeing has dedicated assessment appointments and can accommodate evening and weekend appointments (on request). This allows us to accommodate client assessment with minimal delay.

The cost of psychometric assessment varies depending on the time required for assessment and report preparation. For example, the assessment of ADHD usually requires 1 psychometric assessment and take-home questionnaires. The assessment of ASD or intellectual concerns often requires 2 or more psychometric assessments and take-home questionnaires.

As a guide, in general, our prices are as follows:  

• 1 psychometric assessment (e.g., WISC) + take-home questionnaires + comprehensive report = $2,145 (Including GST)

• 2 psychometric assessments (e.g., WISC & WIAT) +  take-home questionnaires + comprehensive report = $2,860 (Including GST)

• 3 psychometrics assessments (e.g., WISC & WIAT & ADOS) + take-home questionnaires + comprehensive report = $3,575 (Including GST)

• 4 psychometrics assessments (e.g., WISC & WIAT & ADOS & WIM) + take-home questionnaires + comprehensive report = $4,290 (Including GST)

We require a $500 deposit at the time of booking an initial assessment interview and the remainder before the report is released. 

Our assessment process is comprehensive, rigorous and thorough. To do so our assessment process usually includes:

1. An initial consultation of 80 minutes to assess the concerns to be assessed and the psychometric tests needed for reporting.

2. Interviews with relevant sources (e.g., teachers, employers, caregivers, case workers, etc.). Such interviews are usually 30 minutes each (but sometimes longer). For instance, two interviews with relevant sources can be conducted within an hour.

3. Comprehensive assessments (e.g., WAIS, WISC, WIAT, WMS, etc.) usually require 2 to 3 hours of testing on-site. 

4. Assessment interpretation can take up to 2 hours for each assessment. 

5. Most reports our team produce are 2 to 5 pages long. We charge $75 per page for our reports.

6. Clients are invited to attend a 50-minute feedback session to review the report's findings and discuss recommendations. This can be done over the phone or via telehealth. 

As an example**, testing using the WISC and WIAT for a child assessment could include:

• An initial 80 minute consultation

• Two 30 minute interviews with a teacher and another caregiver

• 2 hours of WISC testing and 2 hours of WIAT testing

• 4 hours of assessment interpretation 

• $100 per page of the report

• 50 minute feedback appointment

Other assessments (e.g., university, vocational, immigration, court, NDIS applications / reviews and other reports) are charged at our initial consultation rates for an 80-minute- or 50-minute appointment. Reports for these assessments cost $100 per page. Contact us to inquire.  

Worker's compensation and vehicle accident assessments require additional neurocognitive and psychometric assessments, including symptom validity and impact of injury. Please Contact us to discuss the report needs and for pricing information.

An initial assessment consultation fee must be paid in full at the time of booking. 

GST is included in all assessment fees.
