Gifted Issues Discussion homepage Forums Identification, Testing & Assessment WISC V Subtests

Do some subtests lend themselves more toward being VERY strong indicators than others of math vs vocabulary ability? Obviously Verbal Comprehension Index (VCI) points to ELA strengths. What about:
Visual Spatial Index (VSI)
Block Design
Visual Puzzles
Fluid Reasoning Index (FRI)
Matrix Reasoning
Figure Weights
Working Memory Index (WMI)
Digit Span
Picture Span
Processing Speed Index (PSI)
Coding
Symbol Search

As a generalization, VS, FR, and WM indices have more relationship to math. Not necessarily in that order. There is also the QRI (Quantitative Reasoning), derived from Figure Weights and (optional subtest) Arithmetic, which is considered the best indicator of math ability.
