From a group of 292 youth (269 male, 23 female) who scored 700-800 on the mathematical portion of the College Board's Scholastic Aptitude Test (SAT-M) before age 13, the subscale of 68 students who were of Asian descent (55 males, 13 females) were asked to complete a questionnaire concerning their parents' and grandparents' educational and immigratory histories. Interest in these students' backgrounds stemmed from the huge discrepancy between the percentage of Asian students in this sample (22%) and the percentage of Asian Americans in the general United States population in 1980 (1.5%). Fifty-six of the Asian-background students were of Chinese, Taiwanese, and Korean descent. Most were found to be first-generation Americans and to come from well-educated families. The phenomenal mathematical precocity of these Asian-Americans, especially females, provides a superb example of ability, ambition, and willingness to work hard that is helping set higher levels and a faster pace of educational attainment in the United States. It is predicted that they will be educational and vocational pacesetters for at least a generation or two. (JW)
