The authors look at how 1998 standardized test scores were affected by the scores of students retained under the CPS promotion policy. Findings show that even when the retained students' scores on the Iowa Tests of Basic Skills are counted as if the students had taken the test at a higher grade, the system's scores are still rising overall.
