CBSE 12th Supplementary Date Sheet 2026 Released — Compartment Exam on July 28

The Central Board of Secondary Education has published the CBSE 12th Supplementary Date Sheet 2026 on its official portal, cbse.gov.in. According to the notification, the CBSE Class 12 Supplementary (Compartment) Exam 2026 will be conducted on Tuesday, July 28, 2026, in a single shift, with each paper running for a different duration depending on the subject. Students who could not clear one or more subjects in the main board exam — as well as those seeking to improve their score — can now check the complete subject-wise schedule and start their final round of preparation.

Notably, the exam date has been revised from the earlier July 15 schedule to July 28, giving candidates a slightly longer preparation window. Anyone still relying on the old timetable should switch to the updated CBSE Class 12 Supplementary Time Table 2026 immediately.

Who Is Eligible for the CBSE Class 12 Supplementary Exam 2026?

CBSE has defined three categories of eligible candidates for the 2026 supplementary cycle:

• Compartment candidates (2026 batch): Students placed in the "Compartment" category in the 2026 board exam after failing in one or more subjects.

• Improvement candidates (2026 batch): Students who have already passed but wish to improve their marks in one subject.

• Compartment candidates (2025 batch) — last chance: Students from the 2025 cycle still carrying a compartment. The board permits a maximum of three attempts to clear a compartment subject.

Around 1.63 lakh students fall in the compartment category this year. The context: the CBSE Class 12 Result 2026, declared on May 13, 2026, recorded an overall pass percentage of 85.20%, meaning roughly 2.7 lakh of the 17.8 lakh registered candidates did not clear the main examination held between February 17 and April 10, 2026.
