The notion that testing exerts influence on teaching and learning is accepted by many. In Hong Kong, some educationalists indeed see tests and examinations as one way of instilling positive changes in learners' learning. In 1993, amidst growing concern that Hong Kong students' standard of English was declining, the Hong Kong Polytechnic University (PolyU) proposed to the then University and Polytechnic Grants Committee that a Graduating Students' Language Proficiency Assessment (GSLPA)be devised and introduced to encourage university students to improve their English proficiency. In 1999, the GSLPA-English was mandated by the PolyU as a university exit English test for its graduates. There was no accompanying formal teaching/learning curriculum, as the test was intended to assess students' level of English proficiency rather than their achievement in some taught English courses. Whilst it was reasonable to expect that some students in this university would engage in some form of learning activities to help them learn/train for their exit English test, it was not clear exactly how these students - of their own accord, without a specified learning syllabus and receiving no input from teachers in the regular English classroom - would approach test preparation. Hitherto, there has been little research on how washback operates for learners rather than teachers. This study was principally motivated by a desire to better understand learners as participants in the washback cycle. It investigated how a sample of PolyU graduating students perceived the GSLPA-English as a university exit English test, and whether and how they prepared for it. Initially, the study found that this test was perceived by many respondents as lacking in status and stakes, and that not many took steps to prepare for it. The GSLPA-English was superseded by the lELTS-CEPAS in 2002, when the University Grants Committee, in a further attempt to raise students' awareness of the importance of English proficiency
