What is the Stanford-Binet test?

The Stanford-Binet test is a examination meant to gauge intelligence through five factors of cognitive ability. These five factors include fluid reasoning, knowledge, quantitative reasoning, visual-spatial processing and working memory. Both verbal and nonverbal responses are measured. Each of the five factors is given a weight and the combined score is often reduced to a ratio known commonly as the intelligence quotient, or IQ.

How reliable is the Stanford-Binet test?

The Stanford-Binet test is among the most reliable standardized tests currently used in education. It has undergone many validity tests and revisions throughout its century-long history, and while there are undoubtedly a few issues with the assessment, most results are treated as accurate. Research indicates that individuals with high scores often demonstrate advanced cognitive abilities, while those with significantly below-average scores may benefit from additional educational support or evaluation for learning differences.

Origins of the Stanford-Binet Test

The Stanford-Binet Test traces its roots to the Binet-Simon Scale, a French assessment developed to identify levels of intelligence. The Binet-Simon Scale was created by Alfred Binet and his colleague Theodore Simon in the early 1900s. At the time, French education laws were evolving, and Binet was approached by a government commission. This commission sought a reliable method to identify children with significantly below-average intelligence for their age so appropriate educational interventions could be provided.
