Overview & Quick Facts
The WPPSI-IV measures cognitive development in children ages 2 years 6 months through 7 years 7 months. It is the primary IQ test for preschool and early elementary gifted identification, commonly required for NYC and private school admissions.

Index Scores
Key Takeaway
WPPSI-IV scores at ages 3–4 are less stable than at ages 6–7 — young children's scores can shift 10–15 points between administrations. A single early WPPSI score should not be treated as a permanent measure of ability.

Verbal Comprehension Index
The VCI measures verbal knowledge and reasoning. For young children (ages 2:6–3:11), this index is the primary composite along with VSI.
Examiner names a word; child points to one of four pictures. Tests receptive language — key at younger ages when expressive language is limited.
Questions about everyday objects and events: "What do you use to cut paper?" Measures general knowledge and long-term memory.
"How are an apple and a banana alike?" Tests abstract verbal reasoning and concept formation — only included for the older age band.
Visual Spatial & Fluid Reasoning
VSI measures visual-spatial construction; FRI (ages 4+) measures fluid reasoning with novel visual problems.
Child assembles red-and-white blocks to match a model or picture. Measures spatial visualization, analysis, and fine motor coordination.
Puzzle pieces assembled into a recognizable object. Tests visual-motor integration and spatial reasoning in young children.
Choose which picture completes a matrix. Similar to the nonverbal sections of the NNAT — tests abstract pattern recognition.
Score Interpretation
WPPSI-IV scores are reported as FSIQ and individual Index Scores, all with mean 100 and SD 15. Young children (under 4) also receive the Early Years Composite (EYC).
Full-Scale IQ (FSIQ)
Composite of core subtests. Mean = 100, SD = 15. For ages 2:6–3:11, FSIQ is based on fewer subtests. FSIQ 130+ = 98th percentile — the typical gifted program cutoff.
Early Years Composite (EYC)
For ages 2:6–3:11, the EYC is the primary composite (combines VCI + VSI). FSIQ is available but the EYC is often considered more reliable for very young children.
EYC for under-4s
More reliable than FSIQ at young ages
Percentile Rank
FSIQ 100 = 50th percentile. FSIQ 130 = 98th percentile. NYC private schools typically use 90th+ percentile on the WPPSI as a screening threshold for kindergarten.

Frequently Asked Questions
What is the WPPSI-IV?
The WPPSI-IV (Wechsler Preschool and Primary Scale of Intelligence, 4th Edition) is an individually administered IQ test for children ages 2 years 6 months through 7 years 7 months. It is the primary tool for early childhood gifted identification.
How is the WPPSI-IV different from the WISC-V?
The WPPSI-IV is designed for younger children (up to age 7:7), while the WISC-V is for ages 6–16. There is an overlap at ages 6:0–7:7 where either test can be used — psychologists choose based on the child's maturity and referral question.
What do NYC private schools use the WPPSI for?
NYC private schools (and many other independent schools) require WPPSI-IV results for kindergarten admissions. The test is administered by an educational psychologist and scores are typically submitted alongside the ERB application.
Are WPPSI-IV scores stable in young children?
Scores for children under age 4 can fluctuate significantly. Research shows that IQ scores become more stable around age 7. A score at age 3 may differ substantially from a retesting at age 5.
Can parents prepare their child for the WPPSI-IV?
You cannot teach the test items (they are confidential). However, rich language exposure, puzzles, memory games, and reading aloud support the cognitive skills the test measures. Avoid overly drilling your child — test anxiety can depress scores.
