Army General Classification Test
World War I and World War II created the need for this type of testing and provided a large body of test subjects. The early emphasis (World War I) was on determining the level of literacy (Alpha test) amongst a heterogeneous group. Illiterates were given another test (Army Beta); some enrollees were interviewed. Subsequent testing targeted aptitude in order to better fill roles, such as those provided by officers who obtained commissions from other than the United States military academies, or to meet the need for increasingly complicated skills that came along with technological progress, especially after World War II.
As with other measurement attempts, the AGCT ran into controversy during the era of the Vietnam War. Yet, the requirement did not abate, leading to improvements in the application and use of the standard testing methodology.
Many high IQ societies, such as Mensa, can map their entrance requirements to early AGCT scores. The AGCT was of interest to researchers due to the broad nature of the testee domain (1.75 million men took the original test). The Triple Nine Society accepts a minimum qualifying score of 157 (raw) for membership in its ranks, but only if the test was taken prior to 1976. Also, the TNS accepts a minimum qualifying score of 74 from the similar Naval General Classification Test (NGCT), but only from the years 1954-1977.
The army called this test "GT" around 1969, if you scored 136 or higher before 1978 Mensa will accept the result as proof of being in the 98th percentile.
