This research aims to determine three things: (1) students' reading abilities in Indonesian before using the CIRC model; (2) how the CIRC model can be used to improve students' reading abilities in Indonesian; and (3) students' reading abilities in Indonesian after using the CIRC model. Classroom Action Research is the methodology employed (PTK). The study took place at MIS NU in the Barus District's Pasar Batu Gerigis. Each cycle of this study includes four steps: planning, acting, monitoring, and thinking about what you learned. Participants included 26 fourth-year students (16 male and 10 female) from MIS NU Pasar Batu Gerigis. The study’s overarching goal is to find effective ways to implement the CIRC learning model in Indonesian classes so that students can develop stronger reading skills. Sheets of observations, tests, and written documentation are all examples of data collection methods. It was determined that 1) only 6 students out of a total of 23 had a classical completion percentage of 23 percent with an average score of 4.4 before using the CIRC learning model. Using the CIRC model, 14 students achieved 54% classical completeness and an average score of 6.0 on a reading comprehension assessment after the first cycle of student learning. In addition, students' reading abilities improved even further in the second cycle, with 22 students achieving an 85 percent classical completeness rate and an average score of 8.2. The data presented above demonstrate that students in class IV at MIS NU Pasar Batu Gerigis have improved their reading comprehension to the extent that classical learning has been completed (at the 85% level).
