The highest recorded IQ is no longer listed in the Guinness Book of World records. Various applicants had standardized scores in the range of 170 to 220.Although hailed as having "the highest IQ", the columnist Marilyn vos Savant (born 1946), she scored this on the Stanford-Binet test at the age of 10. The result of 228 is often rounded to 230.
First, you take the test. It depends on how well you answered the test. By this I mean if you answered it like a 22 year-old that is your mental age. Then, you divide your mental age by your real age, next, you multiply that by 100.

The Stanford-Binet intelligence scale is an updated version of the original Binet-Simon scale, developed by Lewis Terman at Stanford University. Terman revised and expanded the original scale to include a wider range of age groups and standardized it for the American population. The Stanford-Binet scale is still used today to assess cognitive abilities in individuals.
Alfred Binet, in collaboration with Theodore Simon, developed the first systematic intelligence test in France in the early 1900s. The test was designed to assess a child's mental age compared to their chronological age. This test laid the foundation for modern intelligence testing.
The first test was invented by Baylor Delshprau in the year 1423!
The concept of mental age was developed by psychologist Alfred Binet and his colleague Theodore Simon in the early 20th century. It was initially used to assess children's intellectual development and abilities in comparison to their chronological age.
The first effective tests of mental faculties were developed by Alfred Binet and Theodore Simon in 1905 with the creation of the Binet-Simon intelligence scale. This test was designed to measure a child's mental age in relation to their chronological age and is considered the foundation for modern intelligence testing.
Binet and Simon designed a test of intellectual abilities in order to identify students who may need additional help in school. Their test aimed to measure a child's mental age compared to their chronological age, providing a tool for educators to tailor instruction to individual needs.
Alfred Binet died on October 18, 1911 at the age of 54.
Alfred Binet is most known for developing the concept of mental age and the first intelligence test, the Binet-Simon scale. His work laid the foundation for the development of the concept of intelligence quotient (IQ) and the theory that intelligence can be measured and predicted.
Philippe de Broca died on November 26, 2004 at the age of 71.
Jacques Philippe Marie Binet died on May 12, 1856 at the age of 70.
Alfred Binet probably deserves the primary credit there, though the intention of his test was to ascertain the ability levels of different children to succeed in elementary school rather than to measure intelligence per se. In any case, it was a valid test of individual differences in aptitude.
