Reading assessment was not a one-dimensional skill that could be evaluated by a single test format. Different test formats measured reading comprehension differently. It was recommended to use more than one test format to have a better understanding of the readers’ comprehension ability. One of the most important issues in the field of reading
assessment that needed to be researched more in depth was applying different test formats to investigate the potential of each test method in assessing reading comprehension of the test takers (Alderson, 2000; Hudson, 2007; Ozuru et al., 2007). It was conceivable that different testing techniques permitted the measurement of different aspects of the reading construct. Therefore it was important to consider what techniques/test formats that were suitable for assessing, as well as what they might typically assess (Alderson, 2000). It was inadequate to measure the understanding of text with only one method by test takers. Different test methods should be applied to gauge students’ reading performance based on their proficiency.
