The earliest intelligence test was designed to place children in appropriate school classes. At the beginning of the 20th century school authorities in Paris asked the psychologist Alfred Binet to devise a method of picking out children who were unable to learn at a normal rate. Binet went on to develop a method that could measure the intelligence of every child-dull, bright, or normal. Binet realized that a person`s ability to solve problems was an indication of intelligence. He found that complex problems, especially those involving abstract thinking, were best for sorting out bright and dull students. Problem-solving ability grows rapidly during childhood. Because of this, Binet decided to make an age scale of intelligence ad chose specific tasks for each age level.
