Outcome-based education (OBE) by Washington Accord (WA) promises to improve the technical education system by clarifying expectations for students and focussing assessment on specific learning outcomes for better measurement of student achievements. Numerous publications describe the process and results of OBE implementation in India. This article is a meta-analysis of research articles documenting the OBE efforts made by Indian engineering institutes. The study implements the established objective approached based reviewing technique. A rubric comprising seven distinct measurements was applied to assess critically selected articles. The detailed assessment indicates that there is a lack of empirical validation of the results obtained by the researchers. The papers were also found to lack a consistent understanding of CO-PO mapping. Hence, there is a clear research gap of statistical validation of the results using pre and postimplementation data for a given improvement.
