Biography Timeline


Terman was born in Indianapolis, Indiana, the son of Martha P. (Cutsinger) and James William Terman. He received a BS, BPd (Bachelor of Pedagogy), and BA from Central Normal College in 1894 and 1898, and a BA and MA from the Indiana University Bloomington in 1903. He received his PhD from Clark University in 1905.


He worked as a school principal in San Bernardino, California in 1905, and as a professor at Los Angeles Normal School in 1907. In 1910, he joined the faculty of Stanford University as a professor of educational psychology at the invitation of Ellwood Patterson Cubberley and remained associated with the university until his death. He served as chairman of the psychology department from 1922 to 1945.


In 1915, he wrote a paper called The mental hygiene of exceptional children. He pointed out that though he believed the capacity for intelligence is inherited, those with exceptional intelligence also need exceptional schooling. Terman wrote that "[bright children] are rarely given tasks which call forth their best ability, and as a result they run the risk of falling into lifelong habits of submaximum efficiency". In other words, nature (heredity) plays a large role in determining intelligence, but nurture (the environment) is also important in fostering the innate intellectual ability. By his own admission, there was nothing in his own ancestry that would have led anyone to predict him to have an intellectual career.


Terman published the Stanford Revision of the Binet-Simon Scale in 1916 and revisions were released in 1937 and 1960. Original work on the test had been completed by Alfred Binet and Théodore Simon of France. Terman promoted his test – the "Stanford-Binet" – as an aid for the classification of developmentally disabled children. Early on, Terman adopted William Stern's suggestion that mental age/chronological age times 100 be made the intelligence quotient or IQ. Later revisions adopted the Wechsler cohort-norming of IQ.


Terman found his answers in his longitudinal study on gifted children: Genetic Studies of Genius. Initiated in 1921, the Genetic Studies of Genius was from the outset a long-term study of gifted children. Published in five volumes, Terman followed children with extremely high IQ in childhood throughout their lives. The fifth volume examined the children in a 35-year follow-up, and looked at the gifted group during mid-life.


Previously, the research looking at genius adults had been retrospective, examining their early years for clues to the development of talent. With Binet's development of IQ tests, it became possible to quickly identify gifted children and study them from their early childhood into adulthood. In his 1922 paper called A New Approach to the Study of Genius, Terman noted that this advancement in testing marked a change in research on geniuses and giftedness. Throughout his life Terman developed several methods for examining individuals with high ability, such as the longitudinal method and above-level testing. Some of these procedures would be adopted by other social scientists studying very different populations.


The suggestions of a significant role for genetics in IQ led Terman to later join the Human Betterment Foundation, a Pasadena-based eugenics group founded by E. S. Gosney in 1928 which had as part of its agenda the promotion and enforcement of compulsory sterilization laws in California. Stern et al. (2017) documented significant long-standing violence inflicted on those identified by eugenicists as unfit and sterilized.


From 1957 until 2018, Terman and his son had a middle school named after them. In 2018, the school board of the Palo Alto Unified School District unanimously decided to rename the school in honor of former Palo Alto City Councilwoman Ellen Fletcher after Terman's involvement with the eugenics movement came to the attention of parents and the school board.
