What is the lowest you can get on an IQ test?
However, the lowest IQ score possible is zero. Can someone actually get this low of a score? In theory, yes. But no one in recorded history has officially scored zero on an IQ test, even if that result is theoretically attainable.

A Breakdown of IQ Scores
1 to 24: Profound mental disability. 25 to 39: Severe mental disability. 40 to 54: Moderate mental disability. 55 to 69: Mild mental disability.
The SSA has a disability listing for "intellectual disorder" (previously it used the term "intellectual disability," and before that, "mental retardation"). A person can be automatically approved for disability based on low IQ if he or she meets all of the criteria in the SSA's listing.
There is no zero point for IQ. We do not think of a person as having no intelligence (although we may be tempted to make that evaluation upon occasion).
Impossible. IQ stands for Intelligence Quotient, which is a numerical measurement of a person's ability to learn. For someone to have an IQ of 0, they would have to be completely unable to learn from experience and would most likely die very early in life.
An average person scores 100 on an IQ test using the Stanford-Binet IQ scale. A score of 137 to 160 is considered the top 1 percent to . 01 percent of all scorers.
Important Considerations. On many tests, a score of 100 is considered the average IQ. Sixty-eight percent of scores fall within one standard deviation of the mean (that is, between 85 and 115). That means that nearly 70% of all people score within plus or minus 15 points of the average score.
Bill Gates IQ is 151.45, despite the fact that he has never publicly disclosed it. He scored 1590 out of 1600 on his SATs in 1973, which converts to a score of 1590 out of 1600. With this IQ, Bill Gates is technically a genius because he is smarter than 99.96% of the population.
Can you have a low IQ and still be smart?
They can, but it's not just that. It's that IQ is a very noisy measure of all intellectual talents averaged together, and some people with unimpressive general IQs can still be extremely talented in particular fields. Even such a stereotypically intellectual pursuit as chess only correlates with IQ at 0.24.
Difficulties talking or talking late. Having problems remembering things. Inability to connect actions with consequences. Difficulty with problem-solving or logical thinking.
If a child has an intellectual disorder or low IQ that limits the intellectual functioning enough to affect his or her life, they might qualify for SSI benefits.
William James Sidis has the World's Highest IQ. Anywhere from 250 to 300 is his IQ score, almost twice the score of Albert Einstein. At the age of eleven, William famously entered Harvard University, becoming the youngest person to enter. He also claimed to be conversant in 25 languages.

Intrapersonal Intelligence is a characteristic of someone that is deeply connected with themselves. This type of person is usually more reserved but at the same time commands great admiration from their peers. Among each of the seven types of intelligence, intrapersonal intelligence is considered the rarest.
The highest IQ possible in the world is theoretically 200, although some people have been known to have an IQ of above 200. Let's discuss how that's possible below. Everyone with an IQ score higher than 110 is lucky enough to have an above average intelligence.
Elon's IQ is estimated to be around 155, while Albert Einstein's is 160. With such a slight margin, Musk is undoubtedly an incredibly smart person. Who is the smartest person on earth in 2022? Born in 1975 in Adelaide, Australia is a mathematician, Terence Tao with an IQ score of 230.
Does an individual's IQ change with age? An individual's IQ does not change with age. In other words: if you did an IQ test now and then another one in 10 years' time, your IQ score will probably be very similar. This is because IQ is always measured relative to other people your age.
To further simplify it: An IQ of 75 means that an 8-year-old child will function intellectually overall at 75% of the average 8-year-old's intellectual functioning ie, at an average of a 6-year-old level. As he ages, he will commensurately function intellectually as a 12-year-old at age 16 years.
