WISC-V Subtests Overview
The WISC-V comprises 16 subtests, categorized as primary or secondary. Typically, 10 primary subtests are administered. These aren’t a single test but a collection to measure different aspects of cognitive function.
Primary vs. Secondary Subtests
The WISC-V utilizes a comprehensive set of subtests to assess various cognitive abilities in children. These subtests are broadly classified into two categories: primary and secondary. The primary subtests are considered essential for deriving the Full Scale IQ (FSIQ) and the five primary index scores. These subtests are administered to provide a comprehensive overview of a child’s intellectual functioning, covering areas such as verbal comprehension, visual-spatial reasoning, fluid reasoning, working memory, and processing speed. The primary index scores, along with the FSIQ, are recommended for a comprehensive description and evaluation of intellectual ability. Three new primary subtests extend the content coverage of the WISC-V and increase its practical application. The test structure includes new and separate measures of visual spatial reasoning, fluid reasoning, and working memory.
Secondary subtests, on the other hand, provide additional information and can be used to further explore specific cognitive strengths and weaknesses. While not directly contributing to the FSIQ or primary index scores, secondary subtests offer valuable insights into areas such as quantitative reasoning, auditory processing, and nonverbal reasoning. The choice of which secondary subtests to administer depends on the individual child’s needs and the specific questions being addressed by the assessment. Overall, the distinction between primary and secondary subtests allows for a flexible and targeted approach to assessing cognitive abilities using the WISC-V.
WISC-V Index Scores
The WISC-V yields several index scores, each measuring a different area of cognitive ability. These include Verbal Comprehension (VCI), Visual Spatial (VSI), Fluid Reasoning (FRI), Working Memory (WMI), and Processing Speed (PSI).
Verbal Comprehension Index (VCI)

This index is vital for a well-rounded understanding of a child’s cognitive abilities. The FRI highlights the ability to adapt and learn.
Working Memory Index (WMI)
The Working Memory Index (WMI) of the WISC-V assesses a child’s capacity to hold and manipulate information in their mind for a short period. This cognitive ability is crucial for learning, problem-solving, and following instructions. The WMI reflects the efficiency of a child’s working memory system, which is essential for tasks like reading comprehension, mathematical calculations, and remembering multi-step directions. A strong working memory allows a child to effectively process and utilize information, contributing to academic success and everyday functioning. The WMI is typically measured through subtests that require the child to remember and manipulate sequences of numbers and visual stimuli. These tasks assess the ability to focus attention, encode information, maintain it in active memory, and perform operations on it. A high WMI score indicates strong working memory abilities, suggesting the child can easily hold and process information. Conversely, a low WMI score may indicate difficulties in working memory, which could impact academic performance and attention; Understanding a child’s WMI score is crucial for educators and clinicians, as it can inform targeted interventions and support strategies. Deficits in working memory can affect a child’s ability to follow classroom instructions, complete assignments, and participate effectively in learning activities. By identifying weaknesses in working memory, appropriate accommodations and interventions can be implemented to help the child succeed.

This index is a critical component of the WISC-V, offering a comprehensive assessment of cognitive functioning. The WMI helps to understand how children learn. It is a very important aspect of cognitive function.
Processing Speed Index (PSI)
The Processing Speed Index (PSI) on the WISC-V measures how quickly a child can process visual information and make simple decisions. It reflects the efficiency with which a child can perform repetitive tasks under time pressure. Processing speed is a fundamental cognitive ability that affects many aspects of academic performance, including reading fluency, writing speed, and mathematics. A higher PSI score indicates that a child can quickly and accurately perceive visual information, make decisions, and implement those decisions. This efficiency allows the child to complete tasks more rapidly and with less cognitive effort. The PSI is typically assessed through subtests that require the child to quickly scan and identify visual patterns, symbols, or shapes. These tasks evaluate the ability to focus attention, discriminate between stimuli, and respond accurately within a limited time frame. A low PSI score may indicate difficulties in processing visual information, which can lead to slower task completion, increased errors, and frustration. These difficulties can significantly impact academic performance, particularly in subjects that require rapid processing of visual material. Understanding a child’s PSI score is crucial for educators and clinicians, as it can inform targeted interventions and support strategies. Children with low processing speed may benefit from accommodations such as extended time on tests, reduced workload, and visual aids. Additionally, interventions aimed at improving attention, visual discrimination, and motor speed can be helpful. The PSI provides valuable insights into a child’s cognitive strengths and weaknesses, guiding educational planning and support. This index is a critical component of the WISC-V, offering a comprehensive assessment of cognitive functioning. The efficiency of a child is very important. Visual information is also important.
Full Scale IQ (FSIQ)
The Full Scale IQ (FSIQ) is derived from seven subtests, summarizing ability across a diverse set of cognitive skills. It’s recommended, along with the primary index scores, for a comprehensive evaluation of intellectual ability and function;
Subtests Contributing to FSIQ
The Full Scale IQ (FSIQ) on the WISC-V is a composite score derived from seven core subtests, providing a comprehensive overview of a child’s intellectual ability. These subtests are carefully selected to represent a range of cognitive domains, ensuring that the FSIQ is a reliable and valid measure of overall cognitive functioning. Understanding which subtests contribute to the FSIQ is crucial for interpreting the WISC-V results and gaining insights into a child’s strengths and weaknesses. The seven subtests that contribute to the FSIQ are: Similarities, Vocabulary, Block Design, Matrix Reasoning, Visual Puzzles, Digit Span, and Symbol Search. Each of these subtests measures a specific cognitive ability, such as verbal comprehension, visual-spatial reasoning, fluid reasoning, working memory, and processing speed. By combining the scores from these subtests, the FSIQ provides a holistic assessment of a child’s intellectual capacity. It’s important to note that while the FSIQ is a valuable summary score, it should always be interpreted in conjunction with the individual subtest scores and index scores to gain a more nuanced understanding of a child’s cognitive profile. For example, a child with a high FSIQ may still have weaknesses in specific areas, such as working memory or processing speed, which can be identified through the subtest scores. Conversely, a child with a lower FSIQ may have strengths in certain areas, such as visual-spatial reasoning or verbal comprehension, which can also be identified through the subtest scores. Therefore, a comprehensive interpretation of the WISC-V results requires careful consideration of all the scores, not just the FSIQ.
