{{main|Race and intelligence (test data)}}
The modern controversy surrounding intelligence and race focuses on the results of IQ studies conducted during the 20th century, mainly in the United States and some other industrialized nations. In almost every testing situation where tests were administered and evaluated correctly, the mean IQ of Blacks was approximately one [[standard deviation]] below that of Whites. Attempted world-wide compilations of average IQ by race generally place Ashkenazi Jews at the top, followed by East Asians, Whites, other Asians, Arabs, Blacks and Australian Aborigines (See [[IQ and the Wealth of Nations]] for an attempted compilation of average IQ for different nations and a discussion of associated measurement problems). The IQ scores vary greatly among different nations for the same group. Blacks in Africa score much lower than Blacks in the US. Some reports indicate that the Black–White gap is smaller in the UK than in the U.S.
Gaps are seen in other tests of cognitive ability or aptitude, including university admission exams such as the [[SAT]] and [[GRE]] as well as employment tests for corporate settings and the military (Roth et al. 2001). Measures of school achievement correlate fairly well with IQ, especially in younger children. In the United States, achievement tests find that by 12th grade Black students are performing on average only as well as White and Asian students in 8th grade; Hispanic students do only slightly better than Blacks. <!-- from the NAEP (mentioned in NYT, WSJ, etc) - reference? --> Whether the gaps are narrowing or not is debated.
