Alfred Binet
He believed intelligence was a collection of mental abilities. His idea for assessing intelligence was seeing how people completed cognitive tasks. Examples include their knowledge of words and how well they followed directions. With the help of Psychiatrist Theodore Simon, Binet created the first standardized intelligence test. The rest was called the Binet-Simon Intelligence scale. Its items were in the order of increasing difficulty and it measured cognitive abilities such as memory, common knowledge, and vocabulary. The test wouldn't last forever because it did not give a single score.
His second attempt was more successful for it offered a single score which represented mental age. With the help of Simon, Binet came up with the mental age method of measuring intelligence. The new test had different items measuring different cognitive abilities it was also in order of increasing difficulty. It took the average of a child a certain age and tested a child the same age to see how much information they knew. If the child had a lower mental age than what children their same age had they were considered to have an intellectual disability.

Lewis Terman
As the spark for how to measure and scale intelligence grew, Lewis Terman came up with the Stanford-Binet test. The test originally came from the Simon-Binet scale. The test was arranged in increasing difficulty. It tested common knowledge and cognitive abilities. It tested for a person's normalcy and separated those with intellectual defective into three groups. The least defective were the morons, more moderate were the imbeciles, and the most severe was the idiots. the test was very targeting to those with defective intelligence and offered no real answers to those who didn't fall into those categories.

William Stern
William was known for creating the intelligence quotient. He wanted to classify people by groups such as types, abilities, or averages. He wanted to look at individuality because it would reveal intelligence and personality. Stern came up with the Intelligence Quotient. It was calculated by dividing a child's mental age by their chronological age with the results from taking an intelligence test. Then the age is multiplied by one hundred which in turn would result in an IQ score.
