The purpose of the study is to investigate the writing strategies employed by the more skilled EFL student writers and how they were applied when students were inventing, composing, and revising their writing. The results were obtained through interviewing three of the more proficient students of the English Department of Chinese Culture University and analyzing the written work of these students. The study showed that these students were rather efficient at using cognitive, metacognitive and social-affective strategies at different stages of writing. The aim of studying writing strategies adopted by the more skilled students is to find Out the useful writing strategies which may be of practical use to less skillful student writers. To help students make use of writing strategies in writing tasks, EFL writing teachers should incorporate the teaching of writing strategies in their instructions.
