This study aimed to evaluate the impact of the three Fridays spelling day and a post-test on the last Friday of the month (3F-PT) technique in improving the spelling and vocabulary skills of Grade 2 pupils at Sta. Rita Elementary School. The research focused on 138 Grade 2 pupils during the academic year 2020 - 2021 and investigated the level of spelling and vocabulary skills on the pre-test and post-test of the experimental group taught using the 3F-PT technique and the control group taught using the traditional method. Mean scores, standard deviations, paired t-test and t-test for independent samples were used as statistical tools for analysis. Findings revealed that the pre-test scores of the both control group and experimental group had a very satisfactory level of spelling and vocabulary skills. However, the experimental group recorded a lower mean score and was seemingly more heterogeneous than the control group based on their standard deviations before the intervention. After the treatment, the post-test scores indicated a significant gain and improvement in spelling and vocabulary skills of learners when exposed to the 3F-PT technique. It is recommended to extend the duration of applying the 3F-PT technique in order to attain more positive results in the spelling and vocabulary skills of Grade 2 learners. Teachers working with lower spelling and vocabulary skills are encouraged to recommend the use of the 3F-PT technique as an alternative teaching method.
