The Central Board of Secondary Education (CBSE) has introduced significant updates to the board exam format and evaluation methods for the 2026 academic session. The revised procedure affects paper structure, answer sheet handling and assessment approaches for students appearing in Classes 10 and 12.
Sectional Answer Paper Structure for Class 10
Under the updated guidelines, the Class 10 Science and Social Science papers are organised into clearly defined sections. Students are required to write answers within designated areas corresponding to each subject subsection, such as Biology, Chemistry and Physics in Science and discrete parts for History, Geography, Political Science and Economics in Social Science. This structured format is designed to streamline evaluation and ensure consistent marking across different subject components. Papers will continue to assess understanding across concepts through a combination of question types, and responses placed outside the assigned sections may not be evaluated.
Competency‑Based and Question Type Mix
The board’s revised pattern incorporates a mixture of question formats intended to test analytical and application skills alongside traditional knowledge. Under this model:
- Around 50% of questions will assess competency and higher‑order thinking, including case‑based, data interpretation and situational problems.
- Approximately 20% will consist of select‑response items (MCQs).
- The remaining 30% will be constructed‑response questions requiring short and long answers.
This balanced approach reflects a move away from rote memorisation toward deeper conceptual understanding, consistent with broader educational reforms.
On‑Screen Marking for Class 12 Evaluation
A major change for Class 12 board exams is the introduction of On‑Screen Marking (OSM) for answer sheet evaluation. Instead of traditional physical answer books, students’ scripts will be scanned and uploaded digitally so evaluators can assess them on computers
This digital evaluation process is expected to:
- Reduce calculation errors and manual handling mistakes.
- Speed up assessment workflows and support transparency.
- Enable wider participation of trained evaluators using secure online systems. (
Schools and teachers have been advised to prepare for this transition, including training and dry runs to familiarise stakeholders with the new tools and protocols.
Implementation and Key Dates
The board exams are scheduled to begin 17 February 2026 for both Class 10 and Class 12 students. These pattern changes will apply to papers conducted in this cycle and are intended to lay the foundation for ongoing improvements in board assessments. Students are encouraged to review the updated formats and practice sectional answer sheets to avoid evaluation issues, especially with the new digital marking system. Schools are also expected to facilitate awareness and training sessions ahead of the exams.
