Is 120 a Good IQ Score? What It Really Means
If you've scored 120 on an IQ test, you might be wondering: is that actually good? The short answer is yes — it's very good. An IQ of 120 places you well above the average population, but let's dive deeper into what this score truly means for your cognitive profile, career potential, and everyday life.
Where Does 120 Fall on the IQ Scale?
On the standard IQ scale (with a mean of 100 and a standard deviation of 15), a score of 120 is exactly 1.33 standard deviations above the mean. This places you in the 91st percentile — meaning you scored higher than approximately 91% of the population.
| Metric | Value |
|---|---|
| IQ Score | 120 |
| Percentile Rank | 91st |
| Classification | Superior |
| Standard Deviations Above Mean | +1.33 |
| Rarity (1 in X people) | ~1 in 11 |
In clinical terminology, a score of 120 falls within the “Superior” intelligence classification (120–129). This is above “High Average” (110–119) but below “Very Superior” (130+). You can check where any score falls using our IQ calculator tool.
What a 120 IQ Means in Practice
Numbers alone don't tell the full story. Here's what a 120 IQ typically looks like in real-world cognitive performance:
🎓 Academic Performance
People with a 120 IQ are typically strong academic performers. They can handle advanced coursework, excel in competitive academic environments, and are well-suited for graduate-level study. Most university graduates have IQs in the 110–125 range.
💼 Career Potential
A 120 IQ provides sufficient cognitive horsepower for virtually any profession. This score is common among professionals in medicine, law, engineering, science, and management. Research suggests that IQ has a moderate correlation with job performance, particularly in complex, knowledge-intensive roles.
🧠 Problem-Solving
People at this level are strong abstract thinkers who can quickly identify patterns, draw inferences from incomplete data, and handle multi-step problem-solving with relative ease. They tend to learn new skills and concepts faster than average.
📖 Learning Speed
Individuals with a 120 IQ typically require fewer repetitions to master new material and can handle more complex information simultaneously. They often enjoy intellectual challenges and self-directed learning.
120 IQ Compared to Other Scores
To put a 120 IQ in context, let's compare it with other common benchmarks:
| IQ Score | Percentile | Classification |
|---|---|---|
| 100 | 50th | Average |
| 110 | 75th | High Average |
| 120 | 91st | Superior ← |
| 130 | 98th | Very Superior |
| 140 | 99.6th | Genius/Near-Genius |
As you can see, 120 places you comfortably in the “Superior” tier — 10 points shy of the “gifted” threshold and Mensa eligibility, but still significantly above average. For a deeper look at all IQ ranges, check out our guide to IQ scores.
Notable People with IQs Around 120
While reported celebrity IQ scores should always be taken with a grain of salt (many are estimates or unverified), several well-known figures are believed to have IQs in the 115–125 range:
- •John F. Kennedy — estimated IQ of 119
- •George Washington — estimated IQ of 118
- •Abraham Lincoln — estimated IQ of 128
- •Barack Obama — estimated IQ of 130
These examples illustrate that extraordinary achievement doesn't require an extraordinary IQ. Leadership, discipline, emotional intelligence, and opportunity often matter just as much as raw cognitive ability.
Can You Increase a 120 IQ?
Your IQ is relatively stable over time, but research shows that certain lifestyle factors can influence your score by several points:
- •Regular exercise improves blood flow to the brain and neuroplasticity
- •Quality sleep (7–9 hours) is essential for optimal cognitive function
- •Continuous learning and intellectual challenges build crystallized intelligence
- •Mindfulness and stress management can improve focus and working memory

The Bottom Line
A 120 IQ is unquestionably a good score. It places you in the top 9% of the population, indicates strong analytical and reasoning abilities, and opens the door to virtually any academic or professional path. While it doesn't qualify for Mensa (which requires the top 2%), it reflects a level of intelligence that most people would be very happy with.
Remember, though, that IQ is just one dimension of who you are. Emotional intelligence, creativity, perseverance, and social skills all contribute to success and fulfillment in ways that a single number cannot capture.
