Research on examinees' response changes on multiple-choice tests over the past 80 years has yielded some consistent findings, including that most examinees make score gains by changing answers. This study expands the research on response changes by focusing on a high-stakes admissions test-the Verbal Reasoning and Quantitative Reasoning measures of the GRE revised General Test. We analyzed data from 8,538 examinees for Quantitative and 9,140 for Verbal sections who took the GRE revised General Test in 12 countries. The analyses yielded findings consistent with prior research. In addition, as examinees' ability increases, the benefit of response changing increases. The study yielded significant implications for both test agencies and test takers. Computer adaptive tests often do not allow the test takers to review and revise. Findings from this study confirm the benefit of such features.
过去80年里关于考生在多项选择题测试中答案变化的研究得出了一些一致的结果，包括大多数考生通过更改答案提高了分数。本研究通过聚焦一项高风险入学考试——GRE修订版普通考试的文字推理和数量推理部分，扩展了对答案变化的研究。我们分析了来自12个国家参加GRE修订版普通考试的8538名数量部分考生和9140名文字部分考生的数据。分析结果与先前的研究一致。此外，随着考生能力的提高，更改答案的益处也会增加。该研究对考试机构和考生都有重要意义。计算机自适应测试通常不允许考生复查和修改答案。本研究的结果证实了这些特点的益处。
