Searchlight Psychology provides psychological assessments and reports for individuals, families and service providers.

Psychological assessments can help inform treatment for both psychological intervention and a number of different professional services such as Paediatricians, Speech Pathologists and Occupational Therapists; effectively forming the foundation for behavioural intervention and planning. We also provide assessments for NDIS planning and to inform NDIS supports and treatment. We are a fully registered NDIS provider and have met Verification from the NDIA to provide services to NDIS participants. We also independently contract our assessment services to government and non-government providers. We have the facilities to assess psychological, intellectual, and functional capacity for both adults and children.

Searchlight Psychology can provide assessments for Neurodevelopmental Disorders related to Intellectual Disability, Autism and ADHD. We also have the capacity to assess children under 7 in Early Childhood Intervention (ECI). Our assessment library consists of multiple formalised and evidence-based tools to help identify a range of intellectual, psychosocial and developmental disorders across the lifespan. Below we provide more detailed descriptions of just a few of the Psychological Assessments we provide here at Searchlight Psychology.

Cairns Psychological Assessments


The Autism Diagnostic Observation Schedule – 2 (ADOS – 2) is a semi-structured standardised assessment instrument designed to diagnose Autism Spectrum Disorders (ASD) from age 12 months through to adulthood. The ADOS-2 consists of a number of play based activities that assess areas related to communication, reciprocal social interactions and behaviours specific to ASD. The assessment takes approximately one to one and half hours depending on the age of the person being assessed. The ADOS-2 is usually used along with a number of other standardised assessments to help determine behaviours consistent with Autism.


The Autism Diagnostic Interview – Revised edition (ADI-R) is a structured clinical interview conducted with parents or caregivers and is designed to evaluate possible Autism or Autism Spectrum Disorders. The interview covers a person’s full developmental history and takes between 1 to 2 hours. The ADI-R used in conjunction with the ADOS-2 is considered to be the most thorough assessment of an adult or child that has suspected Autism or Autism Spectrum Disorders.


The Wechsler Intelligence Scale for Children – 5th edition (WISC-V) is a structured standardised assessment designed to assess the intellectual capacity of children from age 6 through to 16 years and 11 months of age. It consists of a number of items that assess reasoning abilities, working memory, processing speed, verbal comprehension and visual processing and can help identify intellectual disability and learning difficulties. The assessment takes around one and half to two hours to complete and is conducted in conjunction with a number of additional assessments to help inform health services such as Pediatrics, Psychology and Occupational Therapy as well as educational and learning interventions.


Wechsler Preschool and Primary Scale of Intelligence 4th edition (WPPSI-IV) is a structured standardised assessment designed to assess the intellectual capacity of young children ages 2 years and six months of age through to seven years and seven months of age. Depending on the age of the child the assessment takes between 30 minutes to 1 hour to administer.
