The aim of this research is to determine the effect of the cooperative integrated reading and composition learning model on learning motivation for Christian Religious Education & Character Education in class XI of HKBP 2 Tarutung Private High School for the 2023/2024 Academic Year.This research uses a Posttest-Only Control type experimental method. The population is all class XI of HKBP 2 Tarutung Private High School for the 2023/2024 academic year, totaling 160 people. The sample was determined using a technique taken deliberately (purposive sampling) with the specified conditions that the learning material being experimented with was in that class, namely class XI IIS-1 students totaling 32 people as the experimental class and XI IIS-3 totaling 32 people as the control class. The research instrument used a 27 item test. The t test used is the Separated Variance t test according to the test analysis requirements, namely n1=n2 and the variance of the two sample groups is homogeneous. The results of hypothesis testing obtained a value of tcount= 13.9 > ttable (?=0.05; dk=n1+n2-2=62) = ttable 1.669, so H0 is rejected and H1 is accepted. This research concludes that students' motivation to learn Christian Religion & Character Education taught using the cooperative integrated reading and composition learning model is higher than that taught using the conventional learning model in class XI of HKBP 2 Tarutung Private High School for the 2023/2024 Academic Year.
