The results of this case study have shown that the stakeholders were doubtful about the issue of readiness of students, which is claimed by IELTS, and they wanted the test to be clearer about how the students were going to cope with university demands upon gaining entry. In addition, with respect to the content validity of the test, this study found that the tasks in the academic writing test to a large extent do not reflect the kind of tasks candidates are likely to encounter at university. Furthermore, this study pointed out that response validity, on the part of students who may not have understood the rubric of the tasks, is another important factor affecting the students’ performance. Also, the findings of this study suggested that scoring validity could have a significant effect on the students’ scores because of the inconsistency of markers during the scoring process as they may have sometimes failed to assign the students to their corresponding level of proficiency. Consequently, the study provided a set of implications as well as recommendations for future research.
