For the first time, this study combined models and principles of authentic assessment from two parallel fields of applied linguistics as well as general education to investigate the authenticity of the TOEFL iBT speaking module. The study consisted of two major parts, namely task analysis and task survey. Utilizing Bachman and Palmer’s (1996) definition of authenticity, the task analysis examined the degree of the correspondence between the characteristics of the speaking module tasks in the TOEFL iBT test and those of target language use (TLU) tasks. In the task survey, a Likert Scale questionnaire of authenticity was developed by the researcher based on Herrington and Herrington’s (1998; 2006) four criteria of authentic assessment. The questionnaire was sent through email to 120 subjects who had already taken the test in order to elicit their attitudes towards the degree of the authenticity of the speaking section tasks. The results of the task analysis revealed a limited correspondence between the characteristics of the test tasks and those of the TLU tasks. However, the results of the task survey indicated that except for one factor (indicators), most of the test takers had a positive view toward the authenticity of the speaking module tasks in terms of the three other factors (context, student factor, task factor).
