IQ stands for Intelligence Quotient, a measure used to assess cognitive abilities and intelligence relative to the general population. Typically, IQ is calculated using a standardized test, where the average score is set to 100. The score follows a bell curve, meaning that most people score around the average, and fewer individuals score either very low or very high. An IQ of 118 for a 17-year-old is considered above average.
Is an IQ of 118 Good for a 17-Year-Old?
An IQ score of 118 for a 17-year-old is a significant indicator of above-average intelligence. On the IQ scale, 118 falls within the high-average range. It’s important to note that while an IQ score gives insight into cognitive abilities, it doesn’t define a person’s creativity, emotional intelligence, or potential for success in life. For a teenager, a score of 118 could indicate that they have strong problem-solving skills, critical thinking abilities, and are likely to perform well in academic settings.
Understanding IQ Scores: The Bell Curve
The distribution of IQ scores follows a normal distribution (or bell curve). The average score is set to 100, and most people (about 68%) score between 85 and 115. A score of 118 places a 17-year-old just above this range, in the 85th percentile, meaning they outperform 85% of individuals in the same age group.
Here’s a breakdown of the general IQ scale:
- 70-85: Below average intelligence
- 85-115: Average intelligence
- 115-130: Above average (high average)
- 130 and above: Gifted
A score of 118, therefore, reflects a strong intellectual ability, putting the individual in a position where they may excel in areas that require logical reasoning, abstract thinking, and quick learning.
IQ percentile chart
The IQ percentile chart helps to determine where an individual stands relative to the rest of the population. It shows what percentage of people score below a given IQ score. Here is a breakdown of common IQ scores and their corresponding percentiles:
| IQ Score | Percentile | Classification |
|---|---|---|
| 55 | 0.13% | Extremely Low |
| 70 | 2.1% | Borderline |
| 85 | 16% | Low Average |
| 100 | 50% | Average |
| 115 | 84% | High Average |
| 130 | 98% | Gifted |
| 145 | 99.7% | Highly Gifted / Genius |
| 160 | 99.99% | Exceptionally Gifted / Near Genius |
Key Insights:
- Average IQ Score (100): Roughly 50% of the population scores below this level. It represents average intelligence.
- High Average (115): About 84% of people score lower than this, meaning someone with a score of 115 is more intelligent than the majority.
- Gifted Range (130 and above): This group represents the top 2% of the population, indicating significantly above-average intellectual abilities.
- Low IQ Scores (Below 85): These scores represent below-average intelligence, with lower percentiles indicating a smaller portion of the population scoring lower.
Wechsler IQ Classification (WAIS-IV and WPPSI-IV)
The Wechsler scales are among the most widely used tools for measuring intelligence. They include the WAIS-IV (Wechsler Adult Intelligence Scale, Fourth Edition) for adults and the WPPSI-IV (Wechsler Preschool and Primary Scale of Intelligence, Fourth Edition) for younger children. Below is the classification system used by these tests for interpreting IQ scores.
WAIS-IV (Adults, 16 years and older) IQ Classification:
| IQ Score Range | Classification |
|---|---|
| 130 and above | Very Superior / Extremely High |
| 120 – 129 | Superior |
| 110 – 119 | High Average |
| 90 – 109 | Average |
| 80 – 89 | Low Average |
| 70 – 79 | Borderline |
| 69 and below | Extremely Low / Intellectual Disability |
WPPSI-IV (Children, ages 2 years 6 months to 7 years 7 months) IQ Classification:
For younger children, the same general categories apply, although interpreting scores in young children requires more caution due to developmental factors. The classification typically mirrors that of the WAIS-IV but adjusted for developmental expectations:
| IQ Score Range | Classification |

Many careers that require analytical thinking and problem-solving skills, such as engineering, data science, law, and medicine, are well-suited for individuals with higher-than-average IQ scores.
- Learning New Skills:
With higher cognitive abilities, a 17-year-old with a 118 IQ may find it easier to acquire new skills, whether it’s mastering a musical instrument, learning a new language, or developing technical expertise in fields like coding or design.
Limitations of IQ as a Measurement Tool
While an IQ score is a useful indicator of cognitive abilities, it’s essential to remember that it is not the sole determinant of success or capability. Some key points to consider include:
- Emotional Intelligence (EQ):
Emotional intelligence, which includes self-awareness, empathy, and interpersonal skills, plays a critical role in personal and professional success. A person with a high IQ but low EQ may struggle with social interactions or teamwork.
- Creativity and Innovation:
IQ tests typically measure logical reasoning, pattern recognition, and problem-solving, but they do not fully account for creativity or innovative thinking. These skills are equally important in many fields, especially in arts and entrepreneurial ventures.
- Hard Work and Perseverance:
A high IQ doesn’t guarantee success. Motivation, discipline, and perseverance are often more critical factors in achieving long-term goals than raw intelligence alone.
How to Nurture Intelligence in a 17-Year-Old with an IQ of 118
To maximize the potential of a 17-year-old with an IQ of 118, it’s essential to foster both cognitive and emotional development. Here are a few tips to encourage intellectual growth:

- Promote Emotional Intelligence:
Encourage activities that build empathy, communication skills, and emotional regulation. This could include community service, leadership roles, or participation in team sports.
- Encourage Exploration and Creativity:
Allow the individual to explore different interests outside of academics. Creativity, problem-solving in unfamiliar contexts, and innovation are critical aspects of intellectual development.
- Provide a Growth-Oriented Environment:
Create a home environment that supports curiosity and learning. This could include access to books, technology, and diverse cultural experiences.
Can IQ Scores Change Over Time?
IQ scores are generally stable throughout adulthood, but they can vary during childhood and adolescence due to brain development and environmental factors. For a 17-year-old, their cognitive abilities are still evolving, and their score may shift slightly in the coming years, particularly if they continue to engage in activities that challenge their intellect.
FAQs Section
The upper 2% IQ refers to the individuals whose IQ scores are in the top 2% of the population. This typically starts at an IQ of 130 or above. People with IQs in this range are often classified as Gifted or Very Superior and may be eligible for membership in organizations like Mensa, which requires an IQ in the top 2%.
An IQ of 150 is extremely rare, placing an individual in the 99.9th percentile. This means that only 0.1% of the population scores this high or higher. People with IQs in this range are often considered Highly Gifted or Genius, and they are in the top 0.1% of the population in terms of intellectual ability.
An IQ score in the 99th percentile typically falls around 135 to 137. This means that a person with an IQ in this range scores higher than 99% of the general population.
To find your IQ percentile, you can compare your IQ score to a standardized IQ percentile chart. Here’s a simple way to estimate your percentile:
If you’ve taken an IQ test, look up your score on an IQ percentile chart (such as the one below).
The percentile tells you what percentage of people scored lower than you.
Example: If you have an IQ of 120, you are likely in the 91st percentile, meaning you score higher than 91% of the population.
Percentage refers to a proportion out of 100. For example, scoring 85% on a test means you answered 85 out of 100 questions correctly.
Percentile indicates a ranking relative to the rest of the population. For example, being in the 85th percentile means you scored better than 85% of people who took the test, but this doesn’t tell you how many questions you answered correctly—just how your performance compares to others.
Conclusion
An IQ of 118 for a 17-year-old is a clear indication of above-average intelligence. This score suggests strong cognitive abilities, particularly in logical reasoning and problem-solving. However, while IQ is an important measure, it does not capture all aspects of intelligence or potential. To maximize their potential, it’s important for the individual to continue developing their emotional intelligence, creativity, and perseverance alongside their intellectual abilities. With the right environment and encouragement, a 17-year-old with an IQ of 118 can achieve great success in both academics and life.
