The manual itself warns that a single FSIQ can be misleading. For example, a child with VCI=130, PRI=120, WMI=80, and PSI=75 will have an FSIQ around 101—perfectly average. Yet, that child has a significant learning profile (high verbal/visual reasoning paired with poor working memory and slow processing speed), likely struggling in a standard classroom. Therefore, clinicians always examine index-level discrepancies before reporting the FSIQ.
The PSI measures the speed of mental processing, specifically focusing on visual scanning, discrimination, and graphomotor speed.
The is arguably the most sophisticated cognitive assessment tool available for children. It provides a detailed map of how a child learns—their peaks and valleys, their automatic strengths and effortful weaknesses. However, it must never be reduced to a single number. wisc-iv
Below is a showing how a WISC‑IV assessment might be written up for a child, including scores, interpretation, and recommendations.

The tool aids in identifying learning disabilities, evaluating potential giftedness, assessing ADHD—often indicated by lower WMI/PSI scores—and informing clinical interventions.
John presents with , but with clinically meaningful discrepancies: Working Memory and Processing Speed are substantially weaker than his verbal reasoning. This pattern is often associated with specific learning disorders (e.g., in reading fluency or math calculation) and/or attention difficulties. His slow speed and poor working memory may be mistaken for lack of effort or defiance. It provides a detailed map of how a
The uses normalized standard scores. Here is how to read the results:
