This study’s findings reveal that the three teachers have positive perception of implementing the communicative approach in teaching speaking skill based on the emancipated curriculum in Demak Regency. In implementing the communicative approach, guided by classroom observation and the teachers’ lesson plans, the teachers follow the sixteen principles of the communicative approach as outlined by Larsen-Freeman (2011).
