This review addresses three areas of significance in the design, implementation and use of large-scale writing tests that impact ESL writers: writing assessment tasks, rater decision-making, and test washback. First, we discuss integrated writing tasks, as exemplified by the TOEFL iBT, in contrast with impromptu or independent writing tasks. Then we examine results from recent think-aloud studies of raters and their decision-making while reading essays. Finally, we review the current research on test washback in several international contexts. Additionally, we offer some research directions and practical considerations, particularly the need to educate teachers and other test users about the needs of ESL writers.College Composition and Communication Research Initiative Gran
