What is diagnostic testing?
A diagnostic test is used to evaluate whether a child meets the criteria for a particular psychological condition. It involves measuring relevant abilities, skills and functional capacities to determine what might be causing the child's symptoms.
When a child's symptoms follow a certain pattern, it may be appropriate to assign him or her with a clinical diagnosis.
Before categorising a child with a diagnosis, it is important to consider the benefits of doing so. In many cases, a formal diagnosis opens up opportunities for additional support and funding. It is also helpful to identify effective interventions and treatment.
If you suspect your child is suffering from a condition or disorder that is affecting his or her daily life, you should seek professional help.
How does it work?
Diagnostic testing is essentially a process of information gathering. It involves a combination of standardised testing, clinical observation, exploring the child's background and history, as well as parent and teacher interviews and questionnaires.
Proper diagnostic assessment requires time and attention to detail from a trained specialist. If you would like to learn more about our testing service, please get in touch.
*NOTE: be cautious of online quizzes or computerised tests promising to provide a diagnosis or IQ score. These are nearly always unreliable and invalid, and not accepted as evidence of a clinical diagnosis.

Types of standardised tests we use
To provide accurate diagnostic assessments, we use precise tools. Our psychologists use only the top-quality testing instruments available on the market. All of our standardised tests are based in strong scientific research.
In short, the tools we use to assess children are valid and reliable. Our test library is comprehensive, meaning we can assess for most childhood conditions across the five key areas of behaviour, cognition, emotions, school learning and social health.
