says is "a form of assessment in which students are asked to perform real-world tasks that demonstrate meaningful application of essential knowledge and skills." The keyword that Mueller used is "real-world" which gives us an idea of what is authentic testing is all about and why curriculum developers as well as teachers are interested to adopt authentic testing especially in English language courses. Defawu (2010) indicated that unlike standardized assessments, authentic assessments encourage the use of skills and knowledge necessary in real-life situations. Along with other experts, Defawu argued that authentic assessments expect students to organize their understanding of a complex issue. Actually, in order to connect new understanding to their prior knowledge, students need to interpret, synthesize, evaluate, and clarify new and complex information. The problem must have alternative solutions that reflect real-life disciplinary situations to challenge students' thinking processes at a deeper level. In addition, students should present their thinking through extended writing for an audience in outside-of-school contexts. Thus we can say that authentic testing might be a new haven that educators seek to get rid of 'old-fashioned' testing styles that separate students' learning experience from the outside world. Authentic assessment, however, gives a wider range of options for language testing because accurate and effective assessment of language students is essential to ensure that English language learners gain access to instructional programs that meet their needs.
