Abstract. Validity and test fairness have concerned many researchers and scholars in the field of language testing due to its importance in decision making process (Kunnan, 2008; Shohamy, 2001, 2007; Bachman, 2005) as well as the consequences that an unfair practice may bring to test takers ( Kane, 2004, 2006; Xi, 2005a, 2005b). This study was a quantitative investigation of test validity and fairness using an argument-based approach developed by Xi (2010). The main purpose of this study was to quantitatively assess and determine the relationship between a series of inferences in an argument-based framework that can potentially lead to degrees of unfairness and lack of validity in language testing. To this end samples of IELTS test were analyzed and the obtained results determined degrees of fairness which existed among the inferences in the interpretive model.
