WISC-V and WPPSI explained: gifted IQ testing basics
What the WISC-V and WPPSI cognitive assessments measure, who administers them, and how they fit into gifted identification.
Some private schools and gifted programs require an individually-administered IQ test — most often the WISC-V (ages 6–16) or WPPSI-IV (ages 2½–7). Here's the parent's overview.
What they measure
- Verbal Comprehension — vocabulary and verbal reasoning.
- Visual Spatial & Fluid Reasoning — pattern and puzzle logic.
- Working Memory — holding and manipulating information.
- Processing Speed — quick, accurate visual scanning.
- These combine into a Full Scale IQ plus index scores.
Who gives it
Unlike group screeners (CogAT/NNAT), these are administered one-on-one by a licensed psychologist. Many gifted programs use a Full Scale IQ around 130+ (≈98th percentile) as a benchmark — but the exact threshold and the role of index scores vary.
Can you prepare?
You can't 'study' for an IQ test, but you can reduce format anxiety: practice reasoning question types so the thinking feels familiar, and make sure your child is rested and comfortable. The score should reflect ability, not nerves.
Common questions
What IQ score is considered gifted?
Commonly a Full Scale IQ of 130+ (about the 98th percentile), though programs differ and often weigh index scores too.
