The study attempts to determine those factors which exist concurrent with high achievement as measured by the Iowa Test of Basic Skills (ITBS). The data were drawn from sixth grade students enrolled in the Des Moines, Iowa Public Schools during 1974-75. Based on the various analyses, a profile of the individual student most likely to be a high achiever has emerged. While the profile does not hold true in all cases, students exhibiting these characteristics seem to generally exhibit high achievement as measured by the ITBS: female, majority race, family not eligible for free hot lunches, has attended only one or two schools by the time they are enrolled in sixth grade, living with both natural parents, the father has completed at least some college, teacher ratings are high in virtually all areas, the number of brothers and sisters is fairly low, and the student has a higher than average IQ. Overall this study tends to confirm the findings of previous studies which indicate that the factors students bring with them to school are more influential in attaining high achievement, as measured by the ITBS, than any factors over which the school has control and which were included in this study.
