The content of TOEFL iBT is relevant to and representative of the written tasks that students will encounter in academic settings. Although it is impossible that test tasks are exactly the same as TLU tasks, two tasks in writing section of TOEFL iBT are simulations of academic tasks. Based on their study, Cumming ,Grant , Mulcahy-Ernt , and powers provide evidence about the content relevance of integrate test tasks. They interviewed a sample of English as Second Language (ESL) teacher about the new type of test tasks. The teacher gave positive feedback on the tests and viewed them to be realistic and appropriate simulations of academic tasks. They also felt the tasks elicited writing responses from their students that represented the way the students usually performed in their English classes.completely, creating potential bias.
