The negotiated syllabus, also known as a learner-centered and process-oriented syllabus, was introduced as an alternative to a pre-determined syllabus a couple of decades ago. The review of the related studies shows the number of studies in the use of negotiated syllabus in English language teaching is scanty. This study aimed at delving into the impacts of the negotiated syllabus on undergraduate students’ reading comprehension, oral production, and the participants’ perspectives about the syllabus. A mixed-methods research design was employed. Data were collected through researcher-developed tests and an interview checklist. The quantitative section analyzed through independent samples-tests (p=0.05) verified that the negotiated syllabus had a significant effect on the experimental mean scores regarding reading comprehension and oral ability production. In addition, results of the qualitative phase indicated that the use of negotiated syllabus, despite some learner, teacher, and institute-related constraints, has some pedagogical advantages. In light of the results, teachers are recommended to minimize the limitations and implement the negotiated syllabus in teaching English programs to optimize the language learners’ motivation and language achievement.
