In short: Nobody has shown that On-Screen Marking is stricter by design. CBSE says the marking scheme is unchanged. What the 2026 evidence does show is a lower pass rate, a large number of process faults (rescans, manual fallbacks, mix-ups) and re-evaluation cases where marks rose, sometimes sharply. That points more to process quality than to strictness. The data cannot separate OSM from other factors in 2026, so anyone claiming a certain answer is going beyond the evidence.

The Question Students Are Really Asking
After the 2026 Class 12 results, many students felt their marks were lower than their performance deserved, especially in Physics, Chemistry, Biology and Maths. The natural question: "Is on-screen checking harsher than a human with a paper copy?"
Let us separate what is known from what is argued.
What Officials Said
| Claim | Source |
|---|---|
| Only the medium changed: evaluators checked scanned copies instead of hard copies, and the marking scheme is exactly the same | CBSE Chairperson at the time, via NDTV |
| OSM is not new to CBSE. It was first initiated in 2014, paused for infrastructure reasons and reintroduced in 2026 | Ministry of Education, via New Indian Express |
| The system removes totalling errors and does not let an examiner submit with unmarked steps | Officials, via Indian Express |
None of these says digital checking is lenient or strict. They say the standard is the same and the arithmetic is automatic.
What the Data Shows
| Data point | Figure | What it suggests |
|---|---|---|
| Pass rate | 85.20%, down 3.19 points from 88.39% | A lower result year |
| Answer books scanned | About 98.66 lakh | Very large scale in the first year |
| Rescanned for poor quality | 68,018 | Scan quality problems were common enough to matter |
| Manually evaluated after persistent scan problems | 13,583 | A fallback was needed for a real number of books |
| Mix-ups detected | 20 | Rare but serious |
| Applied for re-evaluation or verification | More than 1.6 lakh | Large volume of doubt |
| Reported mark rises | Wide range, some very large | Some original marks did not match the answer books |
Sources are listed in our pass rate analysis.
What the Data Cannot Show
| Gap | Why it matters |
|---|---|
| No official count of how many re-evaluations raised marks | We cannot compute an error rate |
| No before-and-after comparison on the same students | We cannot isolate OSM from the cohort |
| Other changes in 2026 | West Asia disruptions, a special assessment scheme for some candidates and a new assessment scheme cited by officials all sit in the same year |
| No public marking-level audit | We cannot test whether examiners were harsher or stricter than before |
The honest conclusion is that the 2026 numbers are consistent with process errors, but they do not prove that OSM changes how strict marking is.

What Evaluators and Schools Reported
These are reports, not statistics.
- A CBSE evaluator told The Hindu, anonymously, that the decision to use OSM came about two weeks before evaluation started and called the process "a complete mess", saying some answer scripts were not fully scanned and were rejected, and that teachers in remote areas had limited computer familiarity (The Hindu).
- Reports said teachers had to zoom repeatedly on blurred pages and some could check only a few books a day because of slowdowns (Education Post).
- CBSE officials said every re-evaluated book was checked by two evaluators and corrected where marks were not as per the marking scheme.
Together they describe a stressed rollout. That can produce errors in either direction, but the errors that get reported and corrected are the ones that lower a student's marks.
Could Digital Marking Actually Be Fairer?
There are real arguments on both sides.
| Possible advantage of OSM | Possible disadvantage of OSM |
|---|---|
| No totalling mistakes | Scan problems can hide or blur your writing |
| Examiner cannot skip a step entry | Screen reading can be tiring and may speed up skimming |
| Evaluators in other regions keep identity hidden | Mix-ups and missing pages are new failure modes |
| Faster results | Rushed rollout raises error risk |
| Scanned copy lets you check evidence | Access had cost and portal friction in 2026 |
So, Is It Stricter?
Our reading of the evidence:
- No proof that OSM raises the bar. The marking scheme is the same.
- Clear proof that the 2026 process had faults, some of which lowered individual marks until corrected.
- Unknown how much of the pass-rate drop is due to OSM versus other 2026 factors.
If OSM continues in 2027 with better controls, a good chunk of the 2026 problems could shrink. If it continues without them, the same risks apply. Either way, your best defence is a clear answer book and the willingness to check your scanned copy.
What Students Should Do With This
| Action | Reason |
|---|---|
| Write with clear steps and numbering | Easy to mark whether on screen or paper |
| Use dark ink and clean diagrams | Survives scanning |
| Request your scanned copy after results | Evidence beats suspicion |
| Compare with the marking scheme | Only challenge what you can prove |
| Avoid decisions based on rumours | Evidence is still emerging |
Frequently Asked Questions
Is OSM stricter than manual checking?
There is no evidence that it is stricter by design. CBSE says the marking scheme is unchanged. The 2026 problems were mostly about scanning and process quality.
Why did marks drop in 2026 then?
The pass rate fell, but multiple factors overlapped, including exam disruptions in West Asia and a new assessment scheme. OSM process faults also affected some students. The data does not isolate one cause.
Can I trust OSM marks?
You can verify them. Request your scanned copy and check it against the marking scheme. That option is what turns suspicion into evidence.
Will OSM be used in 2027?
Not officially confirmed in the sources we found. CBSE said it would consult stakeholders before deciding.
Does OSM affect Class 10?
In 2026 it did not. Extension to Class 10 was under review.
What should I do if I think my marks are wrong?
Follow the re-evaluation steps and read how examiners award marks.
The Bottom Line
"Is OSM stricter?" is the wrong question to settle on rumours. The better questions are whether your answer book will scan cleanly and whether you will check it after results. Control those two and the debate matters much less to your marks.
