CBSE opens online registration for the Class 12 Supplementary Examination 2026 and sets July 8, 2026 as the deadline for both schools’ submission of the List of Candidates (LOC) for regular students and candidates’ application for private candidates. Multiple outlets report that the LOC submission facility starts on June 30, 2026 on the Pariksha Sangam portal on the CBSE website and remains available until July 8, closing at 11:59 PM. CBSE instructs affiliated schools to submit eligible candidates’ details through school login, including students placed in the “Compartment” category, and to ensure names are uploaded even if students are not reachable. The board also advises schools to inform eligible students about improvement options. For private candidates, CBSE states that only candidates who apply online and complete fee payment by the deadline are allowed to appear. The supplementary examination is scheduled for July 28, 2026, while admit card release is to be announced separately. Outlets also report that CBSE accepts examination fees only through digital payment methods and does not offer challan payments, and that if the fee is not credited by the deadline, the candidature is not accepted.
