Abstract: | The average grade equivalent reading comprehension scores of students in 50 black schools were compared to those of students in 50 white schools under two forms of test administration. Traditional grade level testing resulted in smaller group differences between blacks' and whites' scores than the apparently more valid ability level testing technique. It was concluded that the use of grade level testing with the Iowa Tests of Basic Skills is biased in favor of low scoring subgroups. |
