This study examined the correlation between advanced EFL students' syntactic knowledge and their writing and speaking proficiency to determine whether students' syntactic knowledge can influence their productive skills. A total of 50 advanced students aged between 18 and 25 were chosen purposefully to take part in the study. Four tests, including a placement test, a syntax test from Oxford University Press, a writing test, and one test for speaking proficiency were employed to collect the required data. Because the data for this study were quantitative, a correlational/descriptive design was chosen for the data to be analyzed. The researcher then decided to find a correlation between the students' writing and speaking scores and their syntax scores based on the obtained data. Both the t-test and the Pearson correlation demonstrated that there is no real correlation between the syntactic, speaking, and writing proficiency of the students. Further findings showed that there is no difference between the relationship between syntactic knowledge and speaking proficiency and the relationship between syntactic knowledge and writing proficiency. The implication of this study is that grammatical competence is not a valid predictor for the proficiency of students in writing and speaking courses. If a student’s grammatical competence is low, his proficiency in writing and speaking can still be average or even above average depending on the process of assessing these skills. Additionally, learners must understand that possessing a strong grasp of grammatical knowledge does not inevitably ensure their ability to produce language effectively in spoken or written form.
