IQ Score Ranges: What Every Score Means
IQ scores are one of the most widely recognized measures of cognitive ability, but understanding what a specific score actually means requires context. The modern IQ scale is built on a normal distribution (bell curve) with a mean of 100 and a standard deviation of 15. This means that about 68% of all people score between 85 and 115, and roughly 95% score between 70 and 130.
Whether you have just received your results from a professional assessment or you are curious about where you fall on the scale, this guide breaks down every IQ score range in detail — including what each classification means, how rare it is, and what career paths are commonly associated with each level. If you want a deeper understanding of what IQ measures and how it is assessed, see our complete guide to IQ.
Complete IQ Score Range Chart
The table below summarizes the major IQ score classifications used by most modern intelligence tests, including the Wechsler Adult Intelligence Scale (WAIS) and the Stanford-Binet. Use this as a quick reference to see where any score falls on the overall scale.
| Score Range | Classification | Percentile | % of Population | Rarity |
|---|---|---|---|---|
| 145+ | Genius / Near-Genius | 99.9th+ | ~0.1% | 1 in 1,000 |
| 130–144 | Gifted / Very Superior | 98th–99.8th | ~2% | 1 in 50 |
| 120–129 | Superior | 91st–97th | ~6.7% | 1 in 15 |
| 110–119 | High Average | 75th–90th | ~16.1% | 1 in 6 |
| 90–109 | Average | 25th–74th | ~50% | 1 in 2 |
| 80–89 | Low Average | 9th–24th | ~16.1% | 1 in 6 |
| 70–79 | Borderline | 2nd–8th | ~6.7% | 1 in 15 |
| Below 70 | Extremely Low | Below 2nd | ~2.2% | 1 in 50 |
IQ 130+ — Gifted / Very Superior
An IQ score of 130 or above places an individual in the top 2% of the population. This is the threshold most commonly associated with intellectual giftedness, and it is the minimum score required for admission to Mensa, the world's largest and oldest high-IQ society. People who score in this range typically demonstrate exceptional abilities in abstract reasoning, pattern recognition, and complex problem-solving.
Individuals with IQs in the 130+ range often excel in highly demanding intellectual careers. Research shows that this group is disproportionately represented among researchers, university professors, physicians, surgeons, and engineers. They tend to grasp new concepts quickly, make connections between seemingly unrelated ideas, and thrive in environments that reward deep analytical thinking.
However, a gifted IQ does not automatically translate to success or happiness. Research on gifted individuals suggests they may face unique challenges, including perfectionism, social isolation, and heightened sensitivity. Emotional intelligence, persistence, and social skills remain crucial factors in translating raw intellectual ability into real-world achievement. Curious where specific scores in this range fall?

IQ 120–129 — Superior
Scoring between 120 and 129 places you in the top 9% of the population, a range classified as "superior" intelligence. Interestingly, research has identified the range of approximately 120–125 as a potential "sweet spot" for leadership. Studies suggest that leaders who are significantly smarter than their peers can sometimes struggle to communicate effectively with them, while leaders in this range tend to be intelligent enough to strategize at a high level yet relatable enough to inspire and motivate their teams.
People in the superior range frequently pursue and succeed in careers that demand strong analytical and verbal reasoning skills. Common career paths include law, accounting, senior management, financial analysis, and software development. Academically, they tend to perform well in graduate-level programs and often hold advanced degrees.
While not quite at the "gifted" threshold, individuals in this range possess a significant cognitive advantage in most professional and academic settings. They typically learn new material faster than average and can handle high levels of complexity in their work. For a deeper look at specific scores, explore our pages on IQ 120 and IQ 125.
IQ 110–119 — High Average
An IQ between 110 and 119 is classified as "high average" and represents the upper quartile of cognitive ability. While not in the superior or gifted ranges, individuals who score here enjoy a noticeable advantage in academic settings. They tend to find traditional schooling manageable and are often among the stronger students in a typical classroom, even if they are not always at the very top of the class.
This range is particularly well-suited for graduate education. Many people with high average IQs successfully complete master's degrees and professional certifications. Career paths commonly associated with this range include teaching, nursing, mid-level management, social work, and technical roles. These are professions that require solid reasoning skills and the ability to absorb and apply new information consistently.
People scoring in the 110–119 range should recognize that they have a genuine cognitive edge over the majority of the population — roughly 75% of people score lower. Combined with strong motivation and good study habits, this level of intelligence opens the door to a wide array of professional opportunities. Learn more about what specific scores mean: IQ 110 and IQ 115.
IQ 90–109 — Average
The average IQ range of 90 to 109 is where approximately 50% of the population falls. This is the largest single category on the IQ scale, and it represents the cognitive baseline against which all other scores are measured. If you score in this range, you are in very good company — half of humanity is right there with you.
It is essential to understand that "average" does not mean limited. The vast majority of people with average IQ scores lead successful, fulfilling, and productive lives. IQ measures only a narrow slice of human capability — it does not capture creativity, emotional intelligence, social skills, practical wisdom, artistic talent, or determination. Many entrepreneurs, artists, athletes, and community leaders have IQ scores squarely in the average range.
A wide range of careers is accessible to people in this category, from administrative roles and sales to small business ownership, customer service, and many technical positions. Success in any career depends far more on effort, experience, and interpersonal skills than on IQ points. For more insight into where specific average scores stand, see our detailed breakdowns for IQ 90, IQ 95, IQ 100, and IQ 105.
IQ 80–89 — Low Average
About 16% of the population scores in the low average range of 80 to 89. Individuals in this range have cognitive abilities that are somewhat below the statistical midpoint but are still well within the bounds of normal functioning. Many people in this range complete high school, hold steady employment, and manage the demands of daily life without significant difficulty.
That said, people in the low average range may need more time when working with complex academic material. Abstract or theoretical content can be more challenging, and these individuals may benefit from hands-on, practical learning approaches rather than purely lecture-based instruction. Patience, repetition, and real-world application are often the most effective learning strategies.
Career paths that align well with the low average range include skilled trades (such as carpentry, plumbing, and electrical work), service industry positions, food preparation, transportation, and many other practical careers that value reliability, manual dexterity, and real-world problem-solving over abstract reasoning. These are essential roles that keep society running. Explore more at IQ 80 and IQ 85.
IQ Below 80 — Borderline and Below
IQ scores below 80 fall into the borderline range (70–79) and, below 70, into ranges that may indicate intellectual disability. It is important to approach this topic with sensitivity and to recognize that an IQ score alone does not define a person's potential, value, or worth. People across every part of the IQ spectrum contribute meaningfully to their families, communities, and workplaces.
Individuals who score in the borderline range (70–79) may face challenges with tasks that require complex reasoning or rapid information processing, but many live independently and hold jobs successfully. Those who score below 70 may qualify for additional support services, including educational accommodations, vocational training, and assisted living programs designed to help them achieve the greatest possible independence and quality of life.
Modern perspectives emphasize a strengths-based approach: rather than focusing solely on cognitive limitations, educators and support professionals work to identify and develop each individual's unique abilities, whether in social connection, artistic expression, physical skills, or practical tasks.

How IQ Percentiles Work
A percentile rank tells you the percentage of the population that scores at or below a given IQ score. For example, if your IQ is at the 84th percentile, you scored higher than 84% of the population. Percentiles are a useful way to understand exactly where you stand relative to everyone else, without getting caught up in the raw numbers.
| IQ Score | Percentile | What It Means |
|---|---|---|
| 145 | 99.9th | Higher than 999 out of 1,000 |
| 130 | 98th | Higher than 98 out of 100 |
| 120 | 91st | Higher than 91 out of 100 |
| 115 | 84th | Higher than 84 out of 100 |
| 100 | 50th | Higher than half the population |
| 85 | 16th | Higher than 16 out of 100 |
| 70 | 2nd | Higher than 2 out of 100 |
Frequently Asked Questions
What is a normal IQ score?
A normal or average IQ score falls between 90 and 109. The IQ scale is designed so that 100 is the exact middle, and roughly 50% of the population scores within this range. Scoring in the average range means your cognitive abilities are typical for the general population — and it says nothing negative about your potential for success.
What IQ score is considered gifted?
An IQ score of 130 or above is generally considered gifted or very superior. This places an individual in the top 2% of the population. Many gifted education programs and organizations like Mensa use 130 as their threshold for qualification or membership.
Can your IQ score change over time?
Yes, IQ scores can change over time, particularly during childhood and adolescence. Factors such as education, environment, nutrition, health, and sustained cognitive engagement can all influence scores. However, for most adults, IQ scores tend to remain relatively stable after the mid-20s, with only modest fluctuations.
What percentage of people have an IQ above 120?
Approximately 9% of the population has an IQ score of 120 or higher. This places individuals in the superior range of cognitive ability. About 2% score above 130 (gifted), and fewer than 0.1% score above 145 (genius-level).
Does a higher IQ guarantee success in life?
No. While higher IQ scores are correlated with academic achievement and certain career outcomes, success in life depends on many factors — including motivation, emotional intelligence, social skills, work ethic, creativity, and opportunity. Many highly successful people have average IQ scores, and many people with very high IQs do not achieve traditional markers of success.
