Who Needs to Appear for the Practical Examination?
CBSE has identified two categories of students who are required to appear for practical examinations during the Supplementary Examination 2026.
1. Students with Repeat Practical (RP)
Students who have been placed in the Compartment category due to Repeat Practical (RP) are required to appear only for the practical examination.
Since these students have already passed the theory component, their previous theory marks will be carried forward and considered while preparing the final result. They are not required to reappear for the theory examination.
2. Students with Repeat Theory and Practical Both (RB)
Students who fall under the Repeat Theory and Practical Both (RB) category must appear for both the theory and practical examinations during the Supplementary Examination 2026.
Successfully completing only one component will not be sufficient. Students must qualify in both theory and practical as per CBSE examination rules.
Practical Examination Dates
According to the latest CBSE guidelines, the Supplementary Practical Examinations will be conducted from:
29 July 2026 to 4 August 2026
Schools and examination centres will inform eligible students about the exact subject-wise schedule and reporting time.
Students are advised to stay in regular contact with their schools to avoid missing any updates.
Practical Examination Venue
The examination venue depends on the category of the candidate.
For Regular Students
Regular candidates will appear for their practical examinations in their respective schools.
For Private Candidates
Private candidates will appear for practical examinations at the examination centres allotted for their theory examinations.
In cases where a particular examination centre does not have the required laboratory or facilities for a subject, the concerned CBSE Regional Office will arrange the practical examination at a nearby school or examination centre.
Appointment of External Examiners
To ensure transparency and fairness in evaluation, CBSE has stated that External Examiners will be appointed only by the Regional Offices.
Schools will appoint Internal Examiners from among their own teachers, while the appointment of External Examiners remains the responsibility of the Board.
Schools are not permitted to appoint External Examiners independently under any circumstances.
Practical Answer Books
CBSE has instructed that only the official practical answer books supplied by the Regional Offices should be used during the practical examination.
Examiners are required to complete all entries carefully and accurately before submitting the answer books for evaluation and record purposes.
Uploading Practical Marks
Schools and examination centres conducting the practical examinations must upload the awarded marks on the official CBSE portal on the same day the practical examination is conducted.
Once the marks have been uploaded, they will be treated as final, and no requests for corrections or modifications will be accepted later. Therefore, schools should verify all entries carefully before submitting them online.
Important Instructions for Students
Students appearing for the Supplementary Practical Examination should carefully follow these instructions:
- Contact your school or examination centre on or before 27 July 2026.
- Carry a copy of your result or mark sheet and your admit card.
- Confirm the date, time, and venue of your practical examination.
- Reach the examination venue well before the reporting time.
- Bring all required practical records, project files, laboratory notebooks, and other materials prescribed by your school.
Following these instructions will help students avoid unnecessary complications on the examination day.
Responsibilities of Schools and Examination Centres
CBSE has assigned several important responsibilities to schools and examination centres for the smooth conduct of practical examinations.
These include:
- Preparing a subject-wise list of eligible students.
- Coordinating with the Regional Office for the appointment of External Examiners.
- Informing students well in advance about the examination schedule.
- Preparing a practical examination plan based on examiner availability and the supplementary theory examination timetable.
- Uploading practical marks promptly after the examination.
- Ensuring that all practical records and answer books are submitted as required.
These measures help maintain transparency and consistency throughout the examination process.
Responsibilities of CBSE Regional Offices
The Regional Offices play a vital role in organizing the Supplementary Practical Examination.
Their responsibilities include:
- Preparing centre-wise and subject-wise lists of eligible students.
- Appointing External Examiners wherever required.
- Monitoring the timely completion of practical examinations.
- Ensuring practical marks are uploaded correctly.

This centralized coordination helps ensure uniform implementation of CBSE examination standards across the country.
Tips for Students Appearing in the Practical Examination

- Revise practical experiments and laboratory procedures.
- Complete practical files and record books before the examination.
- Practice viva-voce questions related to the syllabus.
- Carry all necessary documents and stationery items.

Why These Guidelines Are Important

By clearly defining the responsibilities of students, schools, examination centres, and Regional Offices, CBSE aims to ensure a transparent, fair, and well-organized examination process.
Understanding these guidelines in advance allows students to prepare effectively and complete all required formalities without last-minute confusion.
