The research evaluated the ability of project-based learning (PBL) techniques to improve secondary school student academic achievement in Assam. The implementation of inquiry-based projects allows PBL to develop students' critical thinking abilities together with their problem-solving skills and enhance their classroom engagement. This research developed a quantitative method which used surveys and analyzed data with SPSS 22.0. Research findings showed that project-based learning generated positive academic results through statistical data from 70 secondary school students displaying an R-value of 0.974 and R-square value of 0.948 which indicates PBL contributes to 95% of academic performance changes. ANOVA statistical results demonstrated the significance of this relationship with an F value of 1239.170 and p value of 0.000. Significant correlation values proved that PBL increases student engagement and critical thinking and problem-solving abilities. Students in Assam faced infrastructure problems and technology barriers but managed to gain meaningful academic progress through PBL methods which improved both knowledge understanding and practical application of course concepts. The research demonstrates how PBL transforms classroom instruction to create active learning spaces which develop both skill sets and interactivity. Additional measures to deal with existing implementation problems along with proper resource integration will help PBL reach its maximum potential in secondary education. The research shows that PBL stands as a replacement strategy for conventional teaching methods which delivers important benefits for student education results while readying them for future academic and professional demands.
