The present study attempted to investigate the writing performance of EFL learners through process vs. product writing on IELTS test. To do this, the researcher randomly selected 60 candidates who wanted to take the IELTS Test. They had already taken and passed several technical courses regarding the skills in that test. After they were divided into two experimental groups, they were given a writing pre-test. Then, each of the process and product strategies were practiced with the experimental groups. The feedback that was given for the process strategy focused on the steps of writings related to that specific task with little focus on grammatical and spelling mistakes. On the other hand, there were strict corrections on grammatical and spelling mistakes of the writing tasks in product strategy. The results revealed that there was a significant difference between the pretest and posttest scores of the process and product groups. Also, there was a significant difference between the process and product strategy which indicated that process strategy was more effective than the product strategy. Manuscript profile
