Project-based learning is an instructional method centred on the learner. Students develop a question and are guided through research under the teacher’s supervision (Bell, 2010). It is an authentic learning model or strategy in which students plan, implement, and evaluate projects that have real-world applications beyond the classroom (Blank and Harwell, 1997; Dickinson and Allen 1998; Westwood, 2008). The present study investigated the effect of Project based learning on reading comprehension in English Language among Preparatory Stage Learners. The study was delimited to 3rd grade students, who comes under Preparatory Stage as per the structure of Indian Education System, prescribed by the National Education Policy (2020). The present study was experimental in nature. Pre-test post-test control group design was employed to collect the data. A total of 96 students (54 urban students and 42 rural students) were selected from 2 CBSE schools (I urban and 1 rural) by using random sampling technique. A self-constructed Reading Comprehension test was used to measure students reading comprehension in English language.  Project-based learning was used to teach the Experimental group, whereas the control group was taught through traditional teaching method. The collected data was statistically examined using Mean, SD, T-Test, and ANOVA. The results of this study demonstrated a positive and significant difference between students who were taught through project-based learning and those who were taught by the conventional way. Furthermore, rural students demonstrated a significant difference in their scores on reading comprehension in contrast to urban students. Overall, project-based learning proved to be effective in developing students reading comprehension in English language.
