Wechsler Test Wechsler Preschool and Primary Scale of Intelligence (WPPSI-IV) 3

Question 1

For a child aged 2:6–3:11, how many primary index scores are calculated from WPPSI-IV results?

Accepted Answer

Three

Answer

Children in the younger age band receive three primary index scores: Verbal Comprehension Index, Visual Spatial Index, and Working Memory Index.

Question 2

A psychologist is evaluating a 4-year-old suspected of having a developmental language delay. Which WPPSI-IV composite best estimates cognitive ability while reducing language demands?

Accepted Answer

Nonverbal Index

Answer

The Nonverbal Index was specifically designed to minimize verbal and cultural demands, making it ideal when language abilities may artificially depress other composite scores.

Question 3

In which WPPSI-IV age band is the Object Assembly subtest administered?

Accepted Answer

Younger age band only (2:6–3:11)

Answer

Object Assembly is a supplemental Visual Spatial subtest used exclusively in the younger age band (2:6–3:11), often substituted for Block Design.

Question 4

How does the WPPSI-IV target population differ from that of the WISC-V?

Accepted Answer

WPPSI-IV targets younger children (2:6–7:7); WISC-V targets older children (6–16)

Answer

The WPPSI-IV serves preschool and early primary-age children (2:6–7:7), while the WISC-V serves children ages 6–16, with a brief normative overlap at age 6.

Question 5

When a child is exactly 6 years old, which instrument — WPPSI-IV or WISC-V — should a clinician use?

Accepted Answer

Either may be appropriate depending on the child's developmental level and referral question

Answer

Both the WPPSI-IV (ceiling 7:7) and the WISC-V (floor 6:0) have norms at age 6, so the clinician chooses based on the child's functioning level and the purpose of evaluation.
