Abstract A much-debated question in the L2 assessment field is if computer familiarity should be considered a potential source of construct-irrelevant variance computer-based writing (CBW) tests. This study aims to make partial validity argument for an online source-based test (OSWT) designed English placement testing (EPT), focusing on explanation inference. Score interpretations OWST are prop...

this study examined the effects of aural and written prompts under two planning conditions (i.e. pre-task planning and no planning) on complexity, accuracy, and fluency of test takers' writing production. forty learners in an english institute, who had already been classified as intermediate according to the oxford placement test, were assigned to two planning conditions (i.e. no planning and p...

This study utilized Structural Equation Modeling to investigate the washback mechanism, focusing on two design aspects of an English language proficiency test: component weighting (weight assigned to different test papers) and testing methods (item format), and their washback on test preparation. Two months before taking the test, a large sample of test-takers (N 1⁄4 1000) were surveyed regardi...
