Instructional materials are a valuable aid in the language learning of the students. This study was undertaken to evaluate the Department of Education (DepEd) instructional materials used in teaching Meranaw language in Grade 1. The result gives benefits to the teachers on how to make necessary adjustments in the materials to suit the needs and interests of the pupils and to maximize its use in the classroom. The seventy-nine participants were all Grade 1 teachers in Marawi City. This research used the descriptive-evaluative design and utilized a researcher-made questionnaire. The data gathered were statistically treated and interviews were also conducted. The overall evaluation verdict-moderately agreed. One can conclude that something must still be lacking; the materials are not irreproachable; they could stand more refinement and enrichment in some parts. The researcher recommends that there should be more training programs, enlist the cooperation of experts or scholars from different fields such as folklore and literature, and proper monitoring, evaluation and documentation of the MTB-MLE program.
