This study aims to determine the effect of the use of video learning media on student achievement in Christian Religious Education in seventh-grade students at SMP Negeri 2 Simanindo. This research was quantitative, using a quasi-experimental design using a two-group pretest-posttest design. The sample size was 55 students, divided into two groups: an experimental class (using video media) and a control class (using conventional methods). Data were collected through a multiple-choice test (20 items) that had been tested for validity and reliability, a questionnaire (60 items), and a student activity observation sheet. The pretest results showed no significant difference between the initial abilities of the experimental class (average 49.0) and the control class (average 45.61), with a calculated t value (1.3099) < t table (2.0032). After treatment, the average posttest score of the experimental class increased significantly to 80.39, while the control class only achieved 65.96. A one-tailed hypothesis test yielded a calculated t value (5.905) > t table (2.0032), indicating that Ha was accepted. This demonstrates the positive and significant influence of the use of video-based learning media on student achievement in Christian Religious Education (PAK). The regression equation Y = 76.09 + 0.035 X indicates a positive relationship between the use of video media and improved learning outcomes.
