Look at the five Index scores. Is there a spread of more than 23 points between the highest and lowest? If yes, the FSIQ is not a valid average of your child’s ability.

WISC-V UK Interpretive Considerations for Sarah Sample (03/11/2016)
Sophia Martinez displays a distinct cognitive profile characterized by superior verbal and logical reasoning abilities contrasted with significant weaknesses in working memory and processing speed. This pattern is often referred to as a "spiky profile" and is common in children with Specific Learning Disabilities in mathematics fluency or ADHD, inattentive type. Sophia’s difficulty is not with knowing the information, but with retrieving and executing it under time pressure. | Working Memory Subtests | Scaled Score (Mean

Liam demonstrated a relative strength in verbal reasoning. His Verbal Comprehension Index (VCI) of 112 falls within the High Average range (79th percentile). He performed well on tasks requiring word knowledge and verbal concept formation (Similarities). This suggests that Liam has a The WISC-V organizes cognitive ability into five primary
If you only looked at the FSIQ (102), you would conclude Sophia is perfectly "average." You would miss her disability in Working Memory and her gifted potential in Verbal skills. This is why responsible psychologists do not rely solely on the FSIQ when there is significant scatter.
The FSIQ is a summary of global intellectual functioning. However, it is only valid if the scores across indices are consistent. If there is significant scatter (variability), the FSIQ may be "uninterpretable" as a summary score, and the focus must shift to the specific indices.
