This study aims to determine the effectiveness of the Numbered Heads Together (NHT) learning model to improve the Arabic reading ability of students at SDIT Al-Fajar Academy Mataram. This study uses a quantitative method with a quasi-experimental design. The results of the study showed that the use of the NHT learning model in improving students' Arabic reading ability was effective. This was indicated by the rejection of Ho and the acceptance of Ha because the calculated t value of 2.721 was greater than the t table of 2.016 at a significance level of 5%. This is because the Numbered Heads Together (NHT) learning model actively involves students in learning to read Arabic so that they have the ability to read Arabic texts correctly. And the increase in students' Arabic reading skills is significant, where the N-Gain Score in the experimental class reached 50.75 which is included in the medium (effective) category, while the control class only reached 9.03 which is included in the low (ineffective) category. This is because the NHT model encourages students to actively think and participate because each individual has the responsibility to understand the material before conveying the results of the group discussion
