Data from the standardization samples for the Stanford-Binet and Wechsler scales indicate that since the 1970s, the gap in IQ scores between blacks and whites has shrunk by about 4 to 7 points. This suggests that there has been some improvement in the educational opportunities, socio-economic status, and general living conditions of African Americans over the past few decades, which has led to a reduction in the achievement gap. However, there is still some level of disparity, and more efforts are needed to address the root causes of the inequities.
