Abstract

A study investigated the extent of individual differences in academic performance and their growth over the first nine years of education. Data were obtained from analysis of the developmental standard scores of the Iowa Tests of Basic Skills. Findings revealed that the range between the lowest and highest achievers in most grade levels exceeded the eight-year gap in knowledge between average students in the first and ninth grades. Furthermore, the achievement gap increased by around 145 percent between the first and ninth grades. Further findings are presented.
