This research is motivated by the low learning outcomes of students in the PPKn subject caused by a less interactive learning model. This research aims to: (1) determine the application of the Cooperative Script learning model in the PPKn subject. (2) determine the improvement in student learning outcomes by applying the Cooperative Script learning model in the PPKn subject. This research was conducted at SMP Negeri 3 Mazo, Mazo District, South Nias Regency, with research subjects of class VIII Semester II of the 2025/2026 Academic Year totaling 25 people. The research method used is Classroom Action Research (CAR). The research instruments used are observation sheets, student learning outcome tests and documentation. Data collection techniques used are observation, questionnaires, tests, and documentation. The results of the research and discussion concluded that: First, in Cycle I (meetings 1 and 2), teachers' ability in implementing the learning process reached an average of 58.33%, falling in the "poor" category, while in Cycle II (meetings 1 and 2), teachers' ability in implementing the learning process reached an average of 88.33%, falling in the "good" category. Second, in Cycle I (meetings 1 and 2), student activity during the learning process with the implementation of the Cooperative Script learning model reached an average of 69.64%, falling in the "sufficient" category, while in Cycle II (meetings 1 and 2), student activity during the learning process reached an average of 89.64%, falling within the "good" assessment criteria. Third, in Cycle I (first), student learning outcomes reached an average of 67.99, while in Cycle II (second), student learning outcomes increased to an average of 83.39, with the percentage of student learning outcomes achieving completeness increasing to 100%.
