Standardized test
Standardized testing has been a part of American education since the 1800s, but the widespread reliance on standardized is largely a 20th-century phenomenon. For instance the College Entrance Examination Board did not begin standardized testing in connection to higher education until 1900. The College Entrance Examination Board was established and in 1901, the first examinations were administered around the country in nine subjects. This test was implemented with the idea of creating standardized admissions for the United States in northeastern elite universities. Originally, the test was also meant for top boarding school in order to standardize curriculum. With origins in World War I the Army Alpha and Beta tests developed by Robert Yerkes and colleagues. Before then, immigration in the mid-19th century contributed to the growth of standardized tests in the United States. Standardized tests were used in immigration when people first came over to test social roles and find social power and status.
Psychology
Following the Army Alpha and Army Beta tests for soldiers in World War I, mental testing became popular in the US, where it was soon applied to school children. The federally created National Intelligence Test was administered to 7 million children in the 1920s, and in 1926 the College Entrance Examination Board created the Scholastic Aptitude Test to standardize college admissions. The results of intelligence tests were used to argue for segregated schools and economic functions—i.e. the preferential training of Black Americans for manual labor. These practices were criticized by black intellectuals such a Horace Mann Bond and Allison Davis. Eugenicists used mental testing to justify and organize compulsory sterilization of individuals classified as mentally retarded. In the United States, tens of thousands of men and women were sterilized. Setting a precedent which has never been overturned, the U.S. Supreme Court affirmed the constitutionality of this practice in the 1907 case "Buck v. Bell".
