50% percentile • 1 in 2
An IQ of 100 is classified as Average, placing you in the 50% percentile (1 in 2).
The bell curve shows the normal distribution of IQ scores. The mean is 100 with a standard deviation of 15. The highlighted area represents the percentage of people who score at or below IQ 100.
Average intelligence represents the cognitive ability of approximately half the population. Individuals at this level can handle typical work and educational demands and can succeed in many career paths with appropriate training and effort.
An IQ of 100 is the mathematical midpoint of human cognitive ability. By design, IQ tests are normed so that the average score is always 100, with a standard deviation of 15 points. This means roughly 50% of the population scores above 100 and 50% below. The concept was standardized by Lewis Terman in 1916 when he adapted the Binet-Simon test for American use.
Scoring 100 on an IQ test is like bowling a 150 or shooting par in golf — it represents competent, typical performance. Most job roles, educational programs, and daily cognitive tasks are designed around this level of ability.
An IQ of 100 is associated with successful completion of a high school diploma and the ability to handle standard college coursework. Most vocational training and associate degree programs assume cognitive ability near this level.
The difference between IQ 95 and IQ 105 is minimal in practical terms — both are solidly average. IQ differences below 10 points are generally not meaningfully distinguishable in daily life. The threshold where noticeable differences begin is typically around 15+ points (one standard deviation).
Suitable for a wide range of careers. Success depends significantly on skills development, experience, and finding good fit between abilities and job demands.
