Abstract |
|
|
| We introduce a disparity measure, the disproportion statistic, suitable for use in the field of education. The reason for devising a disparity measure specifically for education stems from mounting evidence that extreme disciplinary actions result in greater numbers of repeat offenses and higher dropout rates. We derive the disproportion statistic then apply this statistic to disparities associated with zero tolerance policies as related to high school expulsions. We use the disproportion statistic to quantify the differences among ethnic groups and school settings. Patterns of disciplinary actions in four school settings, Non–Title I Non–Charter, Non–Title I Charter, Title I Non–Charter, and Title I Charter schools are examined. Analysis is based on the most recent data provided by the Office of Civil Rights. The importance of this research is that it is consistent with previous studies that show racial disparities due to zero tolerance policies. This research is unique because it additionally shows statistically significant differences in disparities among school settings as well.
