What Is a Good IQ Score? Complete Guide

If you've just taken an IQ test — or you're about to — you're probably wondering what your score actually means.

Is 110 good? Is 125 exceptional? Where does 100 fall on the spectrum?

The short answer: a score of 100 is exactly average, and anything above 115 puts you in the top 16% of the population. But the full picture is more nuanced than a single number suggests.

In this guide, we'll break down every IQ range, what it means statistically, and why the score alone is only part of the story.

What Is the Average IQ Score?

IQ scores are designed around a concept called normalization. The average score is always set to 100, with a standard deviation of 15 points. This means:

• About 68% of people score between 85 and 115
• About 95% of people score between 70 and 130
• Only 2.2% of people score above 130 (gifted range)
• Only 2.2% of people score below 70

IQ Score Ranges Explained

Here's how psychologists classify IQ scores according to modern standards used by tests like the WAIS-IV and Stanford-Binet:

Note: Different IQ tests use slightly different classifications. The ranges above follow the Wechsler scale, which is the most widely used standard worldwide.

What Is Considered a "Good" IQ Score?

This depends on what you mean by "good." Statistically speaking:

For most practical purposes — career success, academic performance, and everyday problem-solving — an IQ between 100 and 120 is more than sufficient. Research consistently shows that emotional intelligence, work ethic, and social skills often predict life outcomes as strongly as raw IQ.

What Score Do You Need for Mensa?

Mensa International — the world's oldest and largest high-IQ society — accepts members who score in the top 2% of the population. On most standardized tests, this corresponds to an IQ of 132 or higher on the Wechsler scale, or 148+ on some older Stanford-Binet versions.

Does a High IQ Guarantee Success?

Not automatically. IQ is one of the strongest predictors of academic and professional performance — but it is not the only one. Decades of research show that:

• IQ correlates strongly with job performance — but mostly in complex, knowledge-heavy roles
• Emotional intelligence (EQ) predicts leadership and relationship success
• Conscientiousness (a personality trait) often outperforms IQ in long-term goal achievement
• Working memory and processing speed — two components measured in our test — may be better predictors than raw IQ for specific tasks

The psychologist Robert Sternberg famously argued that traditional IQ tests measure only "academic intelligence" — missing creative and practical intelligence entirely. This is one reason our test uses the CHC theory, which captures a much broader range of cognitive abilities.

Can You Improve Your IQ Score?

This is one of the most debated questions in cognitive science. The honest answer:

While your core IQ is largely stable after adolescence, specific cognitive abilities — particularly working memory and processing speed — can be meaningfully improved with the right training.

The Bottom Line

A "good" IQ score is ultimately relative to your goals. A score of 100 means you're exactly in the middle of the human range — which, by definition, is where most people are. A score of 115 puts you ahead of 84% of people. And a score of 130+ places you in the exceptional tier.

But more important than a single number is understanding which cognitive abilities are your strengths and which need development. That's exactly what our test is designed to reveal.
