From the percentage results, it can be said that this summative test has large amount of in-effective distracter. Because ineffective distracters makes the
question easier to answer, and the result of easy question is the gap between lower and upper group become smaller. So it makes the teacher difficult to distinguished
the real comprehension ability of the students. Therefore, ineffective distractors should be replaced or corrected as it affects overall the quality of the questions.
Also the ratio of almost all the items in this test are easy in difficulty, it means the test did not consider the psychological of students in doing the test. Since almost
all of the items are easy in difficulty and it also have many in-effective distracter, it can be said that the English summative test did not test real ability of students
comprehension.
