CBSE Class 12 OSM 2026: What Changes for Students

CBSE Class 12 answer books will be evaluated through On-Screen Marking from the 2026 examinations. For students, the main point is not panic; this circular is about how answer books are checked after the exam. Schools and teachers have separate technical preparation steps.

What CBSE has announced

CBSE’s circular dated 09.02.2026 says the Board has decided to introduce On-Screen Marking for evaluation of Class XII answer books beginning with the 2026 examinations.

This means the evaluation process for Class XII answer books moves into a digital marking workflow. The circular does not mean students should start assuming a different board exam pattern or online written exam from this notice alone.

• Class XII answer-book evaluation moves to OSM from 2026 exams.
• Class X answer books continue in physical mode in 2026.
• Students should keep preparing as per official syllabus and exam instructions.

What changes for students

For a Class 12 student, the most practical change is behind the scenes. Your answer book evaluation is handled through the OSM process after the exam, but the circular is not asking students to do a new student-side registration for OSM.

Students and parents should avoid rumours such as every paper becoming online or students needing special software. The circular focuses on evaluation, school infrastructure and teacher support.

• Do not confuse digital evaluation with online examination.
• Do not trust unofficial claims about changed paper pattern based only on OSM.
• Keep checking CBSE official updates for exam and result-related notices.

Why CBSE is introducing OSM

The circular lists several benefits of On-Screen Marking. These include reduction in totalling errors, automated coordination, faster evaluation and reduced transportation time and cost.

CBSE also mentions that teachers can stay in schools, manpower for verification can reduce, global teacher participation can be possible and there are digital and environmental benefits.

• Lower chance of totalling errors is one stated benefit.
• Evaluation coordination becomes more automated.
• Answer-book movement and transport-related work may reduce.

What schools need to prepare

The technical readiness is mainly a school-side and evaluation-side issue. CBSE lists requirements such as a computer lab with public static IP, Windows OS 8 or above, 4GB RAM and 1GB free space in the C drive.

The circular also mentions modern browser, Adobe Reader, reliable 2 Mbps internet and uninterrupted power. Schools should read the official circular carefully and prepare the lab and systems as per CBSE instructions.

• Computer lab with required system readiness.
• Reliable internet and uninterrupted power.
• Browser, Adobe Reader and system space as listed by CBSE.

Support promised by CBSE

CBSE says it will provide login practice, dry runs, training and call centre support. This matters for teachers and schools because OSM requires comfort with the marking platform.

Parents should not press students about technical OSM details unless CBSE issues a student-facing action. The better role for parents is to keep the student focused on board preparation and verify only official updates.

• Training support is part of the circular.
• Dry runs and login practice are mentioned.
• Call centre support is also listed by CBSE.

Safe next steps for students and parents

Students should use the CBSE Class 12 hub for related board updates and keep official circulars saved when a school message causes confusion.

Parents should check the official PDF before forwarding any claim in class groups. For fake-news safety, use the PrincipalSaab guide on verifying CBSE updates.

• Read the official OSM circular once.
• Do not mix Class X and Class XII evaluation details.
• Avoid panic claims about exam pattern unless CBSE separately announces them.
