I often have people ask me if the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-IV) is part of an educational assessment for children in their early years. A psychoeducational assessment normally consists of an intelligence test such as the WPPSI-IV and an achievement test such as the Wechsler Individual Achievement Test Third Edition (WIAT III). The Wechsler Preschool and Primary Scale of Intelligence has recently become available for use in Australia (by qualified psychologists) which is an updated version of the WPPSI-III.
An intelligence test such as the Wechsler Preschool and Primary Scale of Intelligence is useful for measuring your child’s strengths and weaknesses and can be essential component of a diagnosis of certain academic problems or strengths such as dyslexia, intellectual disability or giftedness.
The WPPSI-IVis an individually administered clinical tool for assessing cognitive ability of children 2.6 years through to 7 years and 7 months. The test provides a general intellectual ability score often referred to as your IQ score. It also provides information on different areas of intelligence such as verbal and practical intelligence.
The Wechsler Preschool and Primary Scale of Intelligence normally takes about 45-60 minutes to complete as part of an educational assessment. Normally a qualified psychologist would also administer other tests within an educational assessment that would normally be expected to take another hour in length. Scoring and writing a report by a qualified psychologist may take from 4 to 6 hours to complete.
There are five main components of the Wechsler Preschool and Primary Scale of Intelligence called Verbal Comprehension, Visual Spatial, Fluid Reasoning, Working Memory and Processing Speed.
Verbal Comprehension measures your child’s understanding of words (receptive vocabulary). In comparison, Visual Spatial and Fluid Reasoning tasks measure your child’s practical ability; however, there is still some understanding of language required such as the ability to follow instructions. Working Memory assesses your child’s capacity to hold and manipulate information in their mind over short periods in an auditory and visual manner. Processing Speed is designed to measure how quickly your child can perform mental tasks.
The WPPSI-IV is often required to be completed to assist in determining if a child may benefit from early school entry as a consequence of giftedness. It may also be useful in assisting teachers with early identification of reading and learning/behavioural issues that may be present in a child. The WPPSI-IV is an important tool in psychoeducational assessments in Adelaide and is used by trusted educational psychology clinics.
