New Delhi: With Union Education Minister Dharmendra Pradhan seeking a detailed report from the Central Board of Secondary Education (CBSE) following widespread complaints from students and parents over technical glitches during the post-result revaluation process, the Center has called in experts from IIT-Madras and IIT-Kanpur and roped in four public sector banks to stabilize the system and strengthen the digital infrastructure of the board.Meanwhile, CBSE has extended the last date to apply for scanned answer sheets for re-checking after the disruptions till midnight of May 25.Sources said Pradhan took serious cognizance of repeated reports of server downtime, payment gateway failures, login disruptions, blurry scanned copies of answer sheets and operational lapses faced by candidates who had applied for verification and revaluation of Class XII board papers.Officials have been asked to explain the reasons behind the technical failures, preparedness measures adopted before opening the reassessment window, and accountability of the agencies and vendors managing the digital infrastructure.The Education Minister directed that a team of professors and technical experts from IIT-Madras and IIT-Kanpur be appointed to assist CBSE in ensuring a glitch-free revaluation process following reports of technical challenges in the post-examination service portal of the board.According to the ministry, expert teams will implement focused technical improvements in systems and technical workflows and will specifically check portal stability, server performance and overall IT infrastructure robustness. The IIT teams will also assist CBSE in taking corrective measures to ensure that the login authentication system, user access mechanisms and payment gateways function smoothly and accurately.Pradhan also spoke to Union Finance Minister Nirmala Sitharaman on technical and payment related issues faced by students during the process. After discussions, it was decided that four public sector banks – State Bank of India, Bank of Baroda, Canara Bank and Indian Bank – will assist CBSE in strengthening its payment gateway infrastructure and integration with the post-examination service portal.Banks are expected to help the Board in setting up robust payment protocols to ensure timely transactions, resolve payment irregularities and facilitate automatic refunds in cases of overpayments. Pradhan also issued instructions to CBSE to completely overhaul its payment gateway system.“Student interests are paramount and all necessary corrective measures need to be taken by CBSE on priority basis to ensure a transparent, efficient and student-friendly system,” Pradhan said in the statement.
