Abstract
The National Institutional Ranking Framework (NIRF) used the weight and sum approach to the combined scores of indicators in the NIRF scores, which were ranked by the institutes. This approach assumes that all indicators contribute independently to the NIRF score in the specified proportions, but this assumption is doubtful as the indicators tend to correlate with each other and some highly so. This indicates a multi-collinearity problem that makes some indicators redundant, and some indicators contribute much less to the NIRF score, which makes them non-contributing. These overlapping and noncontributing indicators make the results invalid. Using data for top 100 engineering institutions of NIRF 2019, these problems are demonstrated, and a solution is proposed. This resulted in a new NIRF Score calculated by only two out of five indicators namely RPC (Research, Professional Practice, and Collaborative Performance) and Perception.
