What are psychological assessments?

A psychological assessment refers to any type of formal standardised assessment conducted by a psychologist to measure aspects of an individual, such as intelligence, development, personality, attitude, behaviour, social or emotional functioning.


‘Standardised’ means the assessment is administered and scored in a predetermined and consistent manner. That is, the questions, instructions, testing conditions, and scoring procedures are the same for each individual. Results are then compared to a norm group (i.e. a large group of individuals who have completed the assessment in order to calculate what is ‘average’). An individual’s score can then be matched to the norm group to determine where their score sits compared to others of the same age (i.e. are they below average, average, or above average).


Types of psychological assessments


Psychological assessments include a range of different ways of gathering information about a person. Common types of psychological assessment include:

  • Interview

  • Observation

  • Test

  • Questionnaire


Psychologists use information and results obtained from psychological assessments to form a diagnosis and guide treatment. A diagnosis is not made on a single assessment, such as test result, as a test result fills only one piece of the puzzle. Information needs to be gathered from multiple sources to form a complete picture of a child. Then a decision is made as to whether the set of symptoms or behaviours meet the criteria for a diagnosis.
