The research used qualitative research design. The Interview was the instrument used to gain the data in this research. The result found that the first school mixed the 2013 and Kurikulum Merdeka. The second school fully implemented and Profil Pelajar Pancasila. The difficulties of implementing it were related to English course time allocation and students’ different interests in learning English.
