This study assesses the effectiveness of remediation activities of Grade 5 pupil's academic performance in the subject Technology and Livelihood Education (TLE). The study used an experimental pretest-posttest design. We chose two schools in the experiment and each school has a class with 50 pupils each. We assigned one school as the independent group and the other one was the experimental group. The researchers worked with the respective teachers in TLE to determine the level of academic performance of the students. First, we administered a pretest during their first grading period. The results for both schools were not impressive, prompting the researchers to advise remediation activities to the experimental group. We advised the independent group to do the usual learning methods. After the intervention, the researcher performed another set of assessment using the results of the second grading period performance. The researchers used a paired t-test to check for significant differences in the scores of the groups. The study found that there is a significant difference in the scores of the pupils after the remediation intervention. Therefore, the researchers concluded that remediation activities can affect the academic performance of the students.
