What does the Stanford-Binet test measure?

The Stanford-Binet test is a test that is used to determine intelligence based on five cognitive abilities. The abilities that the Stanford-Binet test measure are memory, visual-spatial processing, quantitative reasoning, knowledge and fluid reasoning. Overall, the Stanford-Binet test measures what is known as a person’s intelligence quotient, or IQ for short. The Stanford-Binet test was initially created to assess the intelligence of children to help aid educators in placing kids in the right educational settings.

What’s an average IQ score on the Stanford-Binet test?

As the test sits today in 2018, the average IQ score a person can have is 100. The scores that the test measures range from zero to an unknown number at the top of the range. Much debate surrounds the highest possible score that the Stanford-Binet test can produce for an individual. Scores above 145 are considered genius or near genius. Scores between 130-145 are very superior. Scores between 100-115 are above average. Scores between 85-100 are below average. Scores between 70-85 are considered dullness. Scores below 70 are considered deficient.

What is the highest score recorded on the Stanford-Binet test?

There is controversy in the Psychology field as to what the highest recorded score on the test has been. A claim that a gentleman named David Hanna scored 328 on the Stanford-Binet test has been debated if that score is even possible due to the fact that the odds of a score that high are almost mathematically impossible. The scoring of the test compares the tester to the weight of the population. A score of 202 is said to be on in 11 billion and with only around 6.5 billion people on earth, the number seems both astronomical and impossible. Others that have scored high that are documented are William James Sidis with a score between 250-300, Terence Tao with a score between 225-230, Marilyn Vos Savant with a score of 228 and Kim Ung-Yong with a score of 210. To compare, it is said that Albert Einstein’s intelligence quotient was between 160-190. As well, the high IQ society MENSA requires a minimum score of 132 to join the group. Another high-IQ society, the Triple Nine Society, accepts a minimum score of 146 from the newest version of the Stanford-Binet test.
