Wechsler Test Wechsler FSIQ and Index Score Interpretation 3

Question 1

Which WISC-V index was newly separated from Perceptual Reasoning to distinguish spatial from fluid abilities?

Accepted Answer

Visual Spatial Index

Answer

The WISC-V split the old Perceptual Reasoning Index into the Visual Spatial Index and Fluid Reasoning Index.

Question 2

A FSIQ score of 100 corresponds to approximately which percentile rank?

Accepted Answer

50th percentile

Answer

A FSIQ of 100 equals the mean, which is the 50th percentile.

Question 3

The Fluid Reasoning Index (FRI) best measures which capacity?

Accepted Answer

Novel problem solving and inductive reasoning

Answer

Fluid reasoning involves detecting relationships and solving novel problems without relying on prior knowledge.

Question 4

Approximately what FSIQ score marks the 98th percentile, the common threshold for gifted programs?

Accepted Answer

130

Answer

A FSIQ near 130 falls at roughly the 98th percentile, often used as a giftedness cutoff.

Question 5

Before interpreting the FSIQ, a clinician should first check whether the index scores are:

Accepted Answer

Unitary (not too discrepant from one another)

Answer

The FSIQ is most interpretable when the underlying indexes are reasonably consistent (unitary).
