The Distortions of High Steaks
- Campbell’s law states: “The more any quantitative social indicator is used for social decision-making, the more subject it will be to corruption pressures, and the more apt it will be to distort and corrupt the social processes it was intended to monitor.” So if the stakes are high, people will work harder to improve. Such hard work can subvert the accuracy of the measurement. If test preparation is excessive, the tested students will no longer compare to the group on which the test was normed. Schools caught cheating are only the tip of the iceberg. Some schools improve scores by counseling students to dropout into GED programs. Educational triage takes place when teachers focus on “bubble kids” who will pass with help at the expense of others. Lots of test prep takes time from non tested subjects.
