This study explored the challenges of using English as a medium of instruction in four secondary schools in the District of Pandan. Descriptive qualitative design was used and data from the interview were collected from 18 public secondary school teachers of Grade 7 in English, Mathematics, and Science during the school year 2022 – 2023 and their challenges in using English as medium of instruction were analyzed. The findings revealed that teachers could hardly facilitate learning using the language because learners could not comprehend English language. Since learners were not native speakers of English, teachers used code-switching or integrate Filipino or local language in instructions. One of the causes for such a practice is attributed to the fact that learners do not use and practice the language due to the delay in the face to face modality of instruction caused by the pandemic. Thus, learners were not exposed to the language. However, all schools were very supportive to bridge the gap in reading and comprehension problems of the learners. Exposing learners to English reading materials and practicing them to read every day was a big factor to enhance reading and comprehension skills.
