What Is a Good IQ Score?
"Is my IQ good?" It's the most common question people ask after taking an IQ test. The short answer: any score of 90 or above is considered average or better, and the vast majority of people fall in the 85-115 range. But what counts as "good" depends entirely on what you're comparing against and what your goals are.

What "Good" Really Means
Here's the truth most IQ discussions miss: a "good" IQ is whatever allows you to achieve your goals. A score of 100 is perfectly good for running a successful business, raising a family, or excelling in most careers. A score of 130 isn't "better" in any universal sense — it just means certain types of abstract reasoning come more easily.
Research consistently shows that above an IQ of approximately 115-120, additional IQ points have diminishing returns for career success, income, and life satisfaction. Personality traits like conscientiousness, social skills, emotional intelligence, and opportunity become the dominant factors. Many people with 100 IQs outperform people with 130 IQs in their careers because of superior motivation, work ethic, or interpersonal skills.
Good IQ Scores for Specific Goals
For College
An IQ of 100 (average) is sufficient for most college programs. Competitive universities may implicitly select for IQs of 115+, and elite programs (Ivy League, MIT) may average 130+. But IQ is just one factor — GPA, extracurriculars, and test prep matter too. See our SAT to IQ conversion for how standardized test scores relate.
For Most Careers
An IQ of 90-110 is adequate for the vast majority of careers. Demanding fields like medicine (120-130), law (115-130), and engineering (115-128) tend to have higher averages, but individual variation is wide. See our full career IQ pages for specific professions.
For Mensa
130 is the minimum for Mensa membership (98th percentile). Only about 2% of the population qualifies. If your goal is Mensa, you need a "very superior" or "gifted" score.
For "Genius"
140 is the commonly cited genius threshold, though some definitions use 130 or 145. Only about 0.4% of people score this high. See our page on the highest IQ scores ever recorded.
Why You Shouldn't Obsess Over Your Score
IQ tests measure specific types of cognitive ability — logical reasoning, pattern recognition, processing speed, working memory. They do not measure:
- Creativity and artistic ability
- Emotional intelligence and empathy
- Practical wisdom and common sense
- Motivation, discipline, and work ethic
- Social skills and leadership ability
- Musical, athletic, or physical intelligence
A "good" life doesn't require a high IQ. It requires finding work that suits your strengths, building meaningful relationships, maintaining your health, and pursuing goals that matter to you. IQ is one tool in a large toolkit.
Good IQ by Age
IQ is age-normed, so "good" is the same at every age — 100 is always average for your age group. However, cognitive abilities change across the lifespan:
- Children — scores can be volatile; don't over-interpret
- Teenagers — scores stabilizing, good time to test
- Young adults — fluid intelligence peaks
- Adults — most stable period for IQ measurement
- Seniors — crystallized intelligence stays strong
