Communicative Approach is so appealing that it has been implemented in many countries for more than four decades. However, many issues in implementing CLT have been reported in many Asian countries, including its implementation in Indonesian senior high schools. This study aims at finding out the challenges related to Communicative Language Teaching (CLT) teaching practices in Indonesian senior high schools. An electronic questionnaire distributed through social media was used to find the data. 19 English teachers voluntarily participated in this study. The findings showed that the challenges they faced are related to methodology, teachers, students, and educational system.
