摘要：
This study attempts to examine a mid-term English achievement test held in a university in Taiwan. Test items are analyzed, based on assessment devices such as Item Facility, Item Discrimination and Distractor Analysis, to evaluate if the test was appropriately administered in terms of level of difficulty, power of discrimination and function of distractors. Research issues include (1) whether items in four categories are easy or difficult for test takers; (2) whether items can discriminate the performance of top scorers and low scorers; and (3) whether distractors function well or badly. The result of a questionnaire indicates that about 60 percent of test takers think vocabulary is the most difficult category for them, which corresponds with the result of the study. Research findings have shown that vocabulary tests are the most difficult part of the whole test and exhibit the most powerful discrimination. A higher percentage of items in listening, reading, and grammar tests show little or no discrimination power. More nonsense distractors appear in listening tests. The outcome of the analysis suggests that the test needs to be revised. Suggestions are made to improve the quality of the achievement test in order to effectively measure students performance of learning.
