In addition, 15 Teacher I-III and 15 Master Teacher I-II were tapped to evaluate the material. Total enumeration and purposive sampling technique were employed to determine these samples. Two research instruments were utilized in this study, namely: the diagnostic test and the survey questionnaire. Based on the results, the identified four least mastered competencies in Grade 7 English were used to develop Supplementary Modules in Grammar through Literature based on the diagnostic test results. In addition, it can be noted that overall, Master Teacher (M=4.48, HE) rated slightly lower the material than the Teacher I-III (M=4.63, VHE). More so, it was found out that there was no significant difference in the perceived effectiveness of the material between the two groups of respondents. The respondents provided comments and suggestions as additional support to the indicated effectiveness of the module in enriching grammatical and linguistic competence of the Grade 7 learners.
