Modern development

Standardized testing began to influence the method of examination in British universities from the 1850s, where oral exams had common since the Middle Ages. In the US, the transition happened under the influence of the educational reformer Horace Mann. The shift helped standardize an expansion of the curricula into the sciences and humanities, creating a rationalized method for the evaluation of teachers and institutions and creating a basis for the streaming of students according to ability.

Both World War I and World War II demonstrated the necessity of standardized testing and the benefits associated with these tests. Tests were used to determine the mental aptitude of recruits to the military. The US Army used the Stanford–Binet Intelligence Scale to test the IQ of the soldiers. After the War, industry began using tests to evaluate applicants for various jobs based on performance. In 1952, the first Advanced Placement (AP) test was administered to begin closing the gap between high schools and colleges.
