The purpose of this study was to determine the effect of the application of the learning contract method on learning outcomes of Indonesian history. This research method is quasi-experimental research. The population in this study were all students of class X IPS with a total of 86 students. The sampling technique is cluster sampling. The results of the study conducted t-test. Based on the results of the sample class normality test, the sample class has L0 0.00706 < Lt 0.173 with a significant level (α=0.05), which means that the sample classes are normally distributed. To find out whether the two groups of data have a homogeneous variant or not, an F test is carried out, so the sample class has Fcount 1.16 < Ftable 1.88, meaning that the two sample classes have homogeneous variants. The results of the hypothesis test obtained tcount: 3.91 while ttable at a significant level (α = 0.05) is 1.68 meaning tcount > ttable so that H1 is accepted, and Ho is rejected. The conclusion of this study is that there is a positive effect of the application of the learning contract method on the results of learning Indonesian history in class X IPS at SMAN 1 Lareh Sago Halaban which makes students active in learning so that the learning process becomes more meaningful.
