How are board exam papers evaluated in India?
CBSE now scans answer booklets and marks them on‑screen, a shift that has sparked both praise and concern.
In CBSE‑affiliated schools, answer booklets are collected after the exam, scanned and uploaded to an on‑screen marking (OSM) platform. Trained evaluators then view the digital images on computers, marking each response with specialised software that records scores instantly. For objective sections, the software grades automatically; for written answers, markers use a cursor and keyboard to assign marks. Once all papers are processed, the system aggregates scores and releases results online. Students who dispute their marks can request a re‑evaluation through the CBSE portal, after which a clearer scan of their answer sheet is provided for review.

What's happening now
The 2026 CBSE Class 12 results are out. About 18 lakh students submitted 98 lakh answer booklets, which the board scanned and evaluated through an on‑screen marking (OSM) system rather than traditional paper‑based grading. The new process coincided with a drop in the overall pass rate to 85.29%, down from 88.39% the previous year, according to TheWire.in.
Students and parents quickly raised concerns when they tried to view their scanned answer sheets: many reported blurry images, cropped pages and illegible diagrams, making it hard to verify marks (TheWire.in). In response, CBSE recorded 43,980 re‑checking requests via its portal (Indian Express).
Teachers in Tamil Nadu noted that the tougher question papers and the stricter OSM evaluation reduced the state’s pass percentage to 95.25%, a three‑point dip from 2025 (Times of India). A senior principal explained that manual marking often allows leniency on difficult papers, a flexibility that OSM does not provide (Times of India).
How CBSE board papers are evaluated
Collection of answer booklets
After the exam ends, schools gather each student's answer booklet and seal it for transport to regional CBSE centres.
Digital scanning
At the centre, every booklet is scanned at high resolution. The digital file is stored on a secure server and linked to the student's roll number.
Upload to OSM platform
Scanned images are fed into the on‑screen marking system, where they become viewable to authorised evaluators on dedicated workstations.
Marking process
Multiple‑choice items are auto‑graded by the software. For descriptive answers, trained markers use a cursor and scoring rubrics to assign marks directly on the screen, saving their inputs instantly.
Score aggregation and result release
The system compiles marks from all subjects, applies scaling rules and publishes the final scores on the CBSE results portal.
Re‑evaluation request
If a candidate doubts a score, they can file a request through the portal. CBSE then provides a clearer scan of the relevant pages for the candidate to review, and a second marker may re‑assess the response.
Who it affects
Millions of students across India are directly impacted: 18 lakh Class 12 candidates, their parents, and teachers who must adapt to digital marking. The process also touches regional CBSE offices handling scans, IT vendors maintaining the OSM platform, and private tutoring centres that advise students on how to appeal scores. In Tamil Nadu alone, over 83,000 students experienced the new marking regime, while the broader nation saw a dip in pass rates that concerns policymakers and employers alike.

What we still don't know
- Will the OSM system consistently produce legible scans for all subjects, especially diagrams?
- How will the board address the perceived increase in marking strictness for difficult papers?
- What long‑term impact will digital marking have on overall pass percentages?
- Can the re‑evaluation process be expedited to reduce student anxiety?
Questions readers ask
Can I see a physical copy of my answer sheet after results?
CBSE provides a digital scan through its portal; a physical copy is not issued unless you request a re‑evaluation, after which a clearer digital version is sent.
How long does a re‑evaluation take?
The board aims to complete re‑evaluation within 15‑20 working days after the request is lodged, though delays have been reported during peak periods.
Is the on‑screen marking system used for all subjects?
Yes, OSM is applied to every subject, but objective questions are auto‑graded while subjective answers are marked by trained evaluators on the screen.
What should I do if my scanned answer sheet is blurry?
File a re‑evaluation request through the CBSE portal; the board will provide a higher‑resolution scan for the disputed pages.
Will the new system affect my future college admission?
Colleges accept CBSE marks as usual; however, if you feel your score is inaccurate, pursuing a re‑evaluation can ensure the marks reflect your true performance.
