Following the declaration of the Class 12 board examination results, a wave of concern has swept through social media. Numerous students and parents have expressed dissatisfaction over unexpectedly low scores, particularly in core science streams like Physics, Chemistry, Biology, and Mathematics. Many online discussions have pointed fingers at the board’s newly implemented digital evaluation method.
In response to the growing criticism, the Central Board of Secondary Education (CBSE) has issued an official clarification. The Board firmly stated that its new digital evaluation architecture is designed to enhance accuracy, transparency, and consistency, and is “not at fault” for the lower scores. For students who remain unhappy with their marks, the Board has advised following the established, official channels for re-evaluation and verification.
The Controversy: What is On-Screen Marking (OSM)?
For the 2026 examination cycle, CBSE completely transitioned the Class 12 evaluation process to a digital format called On-Screen Marking (OSM).
Under this system:
- Physical answer sheets are collected from exam centers, securely scanned, and converted into high-resolution digital images.
- Examiners evaluate these digital copies on secure computer screens rather than marking physical paper booklets.
- The digital portal automatically records every action an examiner takes, creating a comprehensive digital audit trail.
Social media posts, including appeals from competitive exam aspirants who cleared tough engineering or medical entrances but failed to meet the 75% board criteria, alleged that technical glitches or systemic issues within the OSM framework led to faulty marking.
Why CBSE Stands Firm on the OSM System
Defending the integrity of the digital transition, CBSE highlighted several safety nets embedded within the OSM architecture that make it inherently more reliable than traditional physical checking:
| Traditional Evaluation Pitfalls | How OSM Resolves Them |
| Arithmetic Errors: Examiners manually add up marks per question, leading to totaling mistakes. | Automated Totalling: Marks entered per question are automatically summed by the software, eliminating manual calculation errors. |
| Inconsistent Standards: Subjective bias or different regional speeds can alter grading outcomes. | Standardized Parameters: Digital boundaries ensure uniform parameters and structured marking environments across regions. |
| Step-Wise Marking Omissions: Examiners might accidentally gloss over step marks in long answers. | Enforced Step-Wise Tracking: The software prompts the examiner to explicitly award marks for individual sub-sections of a question. |
The Board further explained that the digital logs track exactly how much time an evaluator spends on each script, as well as any subsequent adjustments made to previously entered scores, ensuring unprecedented professional accountability.
Dissatisfied with Your Scores? Here is the Official 3-Step Remedy
CBSE has reiterated that its long-standing multi-tier grievance redressal system remains active and accessible to anyone who believes their hard work was under-represented. If you wish to challenge your Class 12 results, you must apply online through the official portal (cbse.gov.in) under the “Post Result Activities” section.
The board’s re-evaluation process strictly follows this sequential, three-stage pipeline:
Stage 1: Verification of Marks
- What happens: The board checks for any computation or totaling omissions. They ensure no answer or sub-section was left un-evaluated.
- Outcome: You receive a confirmed total. If a discrepancy is found, your marksheet is updated.
Stage 2: Obtaining a Photocopy of the Evaluated Answer Book
- What happens: Only students who applied for Stage 1 can request a scanned, digital photocopy of their evaluated answer booklet.
- Outcome: This allows you to see exactly how the examiner graded your responses and where points were deducted based on the official marking scheme.
Stage 3: Formal Re-evaluation of Specific Questions
- What happens: If, after reviewing the photocopy, you spot a clear error where a correct answer was marked wrongly or missed according to the answer key, you can challenge specific, individual questions.
- Outcome: A separate, independent subject expert will re-examine those specific items, and the final decision will be binding.
Key Deadlines and What Lies Ahead
Students must adhere strictly to the timelines announced on the CBSE portal, as the windows for verification and re-evaluation are brief and rarely extended. Furthermore, the provisional online marksheets hosted on results.cbse.nic.in and cbseresults.nic.in will only remain available for download until July 31, 2026. Students are advised to secure digital copies on DigiLocker or download their PDFs before this date.
For candidates who need to clear a subject or want to improve their scores to meet university cutoffs, the CBSE Class 12 supplementary and improvement examinations are scheduled to commence on July 15, 2026. The online submission process for the List of Candidates (LOC) for these upcoming tests will open on June 2, 2026.
