The present study attempts to discover the impact of formative assessment on EFL students’writing skill.In fact,the aim of this research is to identify the role of formative assessment in promoting the writing skill of first year master students at Abdel Elhamid Ibn Badis university ,in Mostaganem. We further attempt to demonstrate a fundamental issue which is the lack of the implementation of formative assessment in the writing classroom .In order to confirm our hypotheses,two instruments are used in this investigation to collect data,Students’questionnaire and Teachers’questionnaire. The students’ questionnaire was provided to first year master students,at Mostaganem university ,and the teachers’questionnaire was handed to written expression teachers . The result have shown that formative assessment is not widely implemented in written expression classes ,at Mostaganem university.The two questionnaires revealed that if the learners are assessed formatively ,their writing skill would be improved. The study also recommends some ways throught which the assessors of writing teachers can decrease the writing difficulties that students encounter.
