IQ Score Ranges Explained

A clear, plain-English guide to IQ score ranges, percentiles, and what labels like average, gifted, and genius typically refer to.

Average is typically set at 100 Most people score roughly 85–115 Percentiles explain “how rare” a score is Different tests can use different scoring scales

Quick Overview

Most modern IQ tests are designed so the average score is 100, and scores spread out in a predictable way across the population. That’s why you’ll see ranges like 90–109 labeled “average” and 130+ labeled “gifted” in many references.

Important: IQ is not a measure of your value as a person. It’s a statistical score that estimates certain cognitive skills under specific test conditions. Stress, sleep, motivation, and familiarity with testing can affect results.

Common IQ Score Ranges

The ranges below match the most widely used “average 100” style scoring. Labels can vary by publisher, so treat them as helpful descriptions—not permanent identity tags.

Score Range Common Label What it often means (plain English)
145+ Genius / Exceptional Very rare Strong pattern recognition and reasoning under timed conditions; often excels in complex problem-solving and abstraction.
130–144 Gifted Uncommon Learns quickly, connects ideas easily, and tends to perform well on challenging logic and reasoning tasks.
120–129 Above Average / High Strong Faster-than-average learning and strong reasoning; often does well with new concepts and structured problem-solving.
110–119 High Average Common Solid reasoning skills and good learning pace; typically handles academic or work complexity comfortably.
90–109 Average Range Most common Typical reasoning and learning pace for the general population. This is where the largest portion of people score.
80–89 Low Average Less common May prefer hands-on learning or extra time for complex reasoning tasks; still capable across many real-world skills.
70–79 Borderline Uncommon Can indicate challenges with certain timed reasoning tasks. Context matters a lot—support and environment can change outcomes.
Below 70 Very Low Rare May suggest significant difficulty with standardized reasoning measures. Only a qualified professional can interpret in clinical contexts.

Percentiles: The Easiest Way to Understand “How Rare” a Score Is

Percentiles translate a score into a comparison. Example: being in the 84th percentile means your score is higher than about 84 out of 100 people in the reference group.

Common anchor points (approximate)

  • IQ 100 → around the 50th percentile (middle of the pack)
  • IQ 115 → often around the 84th percentile
  • IQ 130 → often around the 98th percentile
  • IQ 145 → extremely rare (upper tail)

Why Two People Can Score Differently on Different IQ Tests

Not all tests measure the exact same skills in the exact same way. Differences can come from:

  • Scale differences: some tests use different scoring spreads
  • Question types: verbal, spatial, logic, memory, speed, etc.
  • Timing: timed vs untimed conditions change performance
  • Practice effects: familiarity with test patterns can lift scores
  • Life factors: sleep, stress, motivation, distractions

What IQ Measures (and What It Doesn’t)

IQ scores usually reflect performance on reasoning tasks—often including pattern recognition, logic, and problem-solving speed. IQ does not directly measure character, creativity, kindness, leadership, wisdom, or real-world experience.

Best use: Treat your score as a “snapshot” that helps you understand how you performed on this style of reasoning test today. If you take a different test or retake later, some change is normal.
