This study aims to: (1) Analyze the effectiveness of the An-Nahdliyah method in improving the ability to read the Qur'an among students at the Al-Maghfiroh Al-Qur'an Education Park, and (2) Identify supporting and inhibiting factors in its implementation. The background of this study is based on the fact that some students still experience difficulties in pronouncing the hijaiyah letters and applying the rules of tajwid, so a systematic learning method is needed that is appropriate to the characteristics of early childhood. The study uses a descriptive qualitative approach with data collection techniques through observation, interviews, and documentation. The research informants consist of the head of the institution, ustaz/ustazah, and students. Data are analyzed through the stages of reduction, presentation, and verification to obtain a comprehensive picture of the application of the An-Nahdliyah method and its impact on the ability to read the Qur'an. The results of the study indicate that the An-Nahdliyah method is effective in improving the ability to read the Qur'an among students. This effectiveness is reflected in four main indicators: the accuracy of pronunciation of the letters, the application of basic tajweed rules, reading fluency, and the students' active participation in learning. Furthermore, the study also found supporting factors in the form of the competence of the ustaz/ustazah, institutional support, and parental involvement, while inhibiting factors include the students' regular absence, differences in individual abilities, and suboptimal support at home. Thus, the An-Nahdliyah method can be said to be relevant and effective in improving the ability to read the Qur'an while building the students' motivation and active participation. However, the success of its implementation is highly dependent on the support of teachers, institutions, and families, and it is necessary to anticipate emerging obstacles to maximize learning outcomes.
