<em>The objectives of this study to </em><em>develop a model of religious extracurricular activities and produce a model book of </em><em>the religious extracurricular activities based on a practical scientific approach. </em><em>The research method used was a Research and Development (R and D) with the Borg and Gall model. The data collection tool was observation sheet. Then the data were analyzed quantitatively by using Aiken V index calculation, if the index is 0.0 <V ≤ 0.200 it is said that the validity is very low, if 0.200 <V ≤ 0.400 is said to be low, 0.400 <V 600 0.600 is said to be practical, 0.600 <V 800 0.800 is practical, 0800 < V ≤ 1.00 can be said to be very practical.</em><em><em> The results of the practicality test of the religious extracurricular activity model based on the scientific approach obtained an average of 0.85 in the <em>very practical category after field trials were carried out, so that the model of religious extracurricular activities was feasible to use.</em></em></em><em></em>
