Hiller (2002) defines the summative assessment occurs at the end of learning, where formative assessment occurs during the course of learning to assist teachers and learners to know the progress of learning. Moreover, formal assessment methods may be used in the informal assessment throughout the course of learning. That is, formal assessment contributes to the identification of achieved outcomes as specified by the learning program, where informal assessment does not necessary have to be (Hillier, 2002).
Brown (1994) and Kruidenier (2002) view that assessment for learning as informal assessment, and assessment of learning as formal assessment. Ecclestone (2004) argues that formative assessment is synonymous with continuous assessment or courses without end examinations. Fordham et al. (1995) also argue that summative and formative assessment should be equally important and useful. Derrick and Ecclestone (2008) further suggest that summative assessment should be used formatively. This study intends to adopt Derrick and Ecclestone's (2008) theory and put it into practice. TOEIC test assess English learners at the end of their learning, that is, it is more of a summative assessment, where this study implemented the test formatively. This study intends to collect data on English learners' attitudes toward formatively use of summative language assessment tool. Furthermore, the study focuses the English proficiency test (TOEIC) as a task oriented tool for English learners in the learning process.
