Average IQ for a 5-Year-Old

Quick Answer: What is the Average IQ for a 5-Year-Old?

The average IQ score for a 5-year-old is 100. The "normal" range falls between 85 and 115, which includes roughly 68% of all children. A score above 130 is typically considered "gifted," while scores below 70 may indicate developmental delays requiring support.

If you are wondering whether your 5-year-old is "smart for their age," you aren't alone. Age 5 is a critical milestone. It is often when children enter formal schooling (Kindergarten), and it is a common age for the first round of standardized testing for private school admissions or Gifted and Talented (G&T) programs.

However, measuring intelligence at this age is distinct from testing adults. Here is the breakdown of what the numbers mean, the signs of high potential, and the specific tests used for this age group.

The IQ Score Breakdown for 5-Year-Olds

IQ (Intelligence Quotient) is not a measure of how much your child knows (like counting to 100), but rather how well they can reason and solve problems compared to other children born within 3 months of them.

IQ Score Range Classification Percentile
130+ Very Superior (Gifted) Top 2%
116 - 129 High Average Top 16%
85 - 115 Average (The Norm) Middle 68%
70 - 84 Low Average Bottom 16%

Is My 5-Year-Old Gifted? (Signs to Look For)

While an IQ test provides a number, observation often provides the first clue. High IQ in a 5-year-old often manifests as "asynchronous development"—where their mind is miles ahead of their emotional maturity. Look for these markers:

  • Advanced Vocabulary: They use specific words (e.g., "actually," "complicated," "structure") rather than generic ones, and understand sentence nuance.
  • Pattern Recognition: They notice repeating patterns in floor tiles, numbers, or music beats that other kids miss.
  • Intense Curiosity: They don't just ask "What is that?" but "How does that work?" and "Why did it happen?"
  • Memory: They can recall specific details from a trip taken months ago.

The Test: What is the WPPSI-IV?

If you take a 5-year-old to a psychologist for testing, they will likely administer the WPPSI-IV (Wechsler Preschool and Primary Scale of Intelligence). This is the "Gold Standard" test for children aged 2 years 6 months to 7 years 7 months.

Unlike adult tests which are heavy on reading, the WPPSI-IV for 5-year-olds feels like a series of games. It tests:

  • Verbal Comprehension: Defining words or answering common knowledge questions.
  • Visuospatial: Putting blocks together to match a pattern.
  • Fluid Reasoning: Picking which picture comes next in a sequence.
  • Working Memory: Remembering picture cards in order.
⚠️
Important Note on Stability:
IQ scores at age 5 are less stable than scores at age 8 or 9. A child's brain is developing rapidly; a "spurt" in development can change a score significantly in just one year. Unless testing is required for school admission, many experts recommend waiting until age 7 for a more permanent baseline.
