The research seeks to interpret the perceptions of students with different reading profiles based on their experiences with the Philippine Informal Reading Inventory (Phil-IRI) process. Additionally, it analyzes the perceptions of Filipino subject teachers regarding the Phil-IRI results to propose improvements and the creation of effective reading programs. A combination of qualitative and quantitative methods was employed in analyzing the data. Teachers answered surveys using a Likert Scale to capture their perceptions, while the Phil-IRI tool was used to gather the overall reading profiles of students from Grades 7 to 10 in Junior High School. Findings revealed that Phil-IRI significantly contributes not only to assessing students' reading abilities but also to motivating them toward active learning and strengthening their self-awareness regarding their skills. For teachers, Phil-IRI serves as an essential guide for monitoring students' progress and for designing more effective teaching strategies. The study recommends using Phil-IRI as a launching point for developing reading programs aimed at further enhancing students' reading proficiency and overall reading levels.
