Do CBSE examiners know whose answer sheet it is?
Not by name. Before marking, CBSE swaps each roll number for a made-up one, and a student may not write a name on the answer book. What that does and does not hide.
Not by name, under CBSE's Examination Bye-Laws (1995, updated to 2004). Before marking, the real roll number on each answer book is changed to a fictitious number - a made-up code. Students may not write their name, or any mark that shows who they are. Doing so counts as unfair means - the board's term for cheating - and the result is not declared.
Are CBSE answer sheets marked anonymously?
Yes, in the sense that the examiner sees a code, not the student. This is sometimes called anonymous marking. CBSE's Examination Bye-Laws, from 1995 and last updated in 2004, set it out in two steps. First, the answer books arrive from exam centres under each student's real roll number. Then that number is replaced:
"All the answer books received from the examination centres in real roll numbers of the candidate shall be converted into fictitious numbers."
Marking then happens on the coded books. The Bye-Laws say: "All answer books bearing fictitious roll numbers shall be evaluated by approved examiners". An examiner holding a coded book has no roll number to look a student up by.
Who changes the roll numbers?
A team called Secrecy Officers, not whoever happens to handle the bundle. The Bye-Laws put them under a Chief Secrecy Officer, appointed by the board's Chairman. That person is a senior academic, such as a college professor or principal. The team must promise to keep the work confidential.
The answer books themselves are treated as confidential documents. Only people named by the Controller of Examinations or the Chairman may handle them.
Can you write your name on the CBSE answer sheet?
No. The Bye-Laws do not allow a student to write their name or sign the answer book. They also bar "any sign or mark which may disclose his/her identity to the examiner". A student who breaks this rule is treated as having used unfair means. The rule says the result is then not declared, and the student may face further penalty.
The rule covers more than a name. It covers a signature and any sign or mark that could show who you are. If you are unsure whether something may be written, ask the invigilator first.
What are the roll number rules on the answer sheet?
Your answer book reaches the board under your real roll number. That number is the only identity it should carry. Write it where the answer book and the invigilator tell you to, and nowhere else. The secrecy officers then swap it for the fictitious number before any marking starts.
How does CBSE keep a name off the answer sheet?
With three separate rules, each covering a different gap:
- The student may not write a name or any identifying mark.
- Secrecy officers change the roll number to a fictitious number before marking.
- People with a close relative sitting the board's exams that year may not take certain roles. The Bye-Laws list paper setters, moderators, secrecy officers, head examiners and coordinators.
The Bye-Laws do not contain a sentence saying "the examiner never sees the name". That the name stays hidden follows from the rules above. This page says so rather than quote words CBSE has not written.
What does a fictitious number not hide?
- Handwriting. The code hides the name, not the writing. CBSE's own handbook on assessment lists "the halo effects associated with hand-writing, grammar and spelling" as a difficulty in marking. That is one reason two examiners can differ.
- Internal assessment. The 20 marks a school gives are given by teachers who know the student, by design. That is a different process, covered in internal assessment: the marks with one attempt.
Does coding change how marks are given?
No. Coding decides who the examiner thinks the answer belongs to - nobody in particular. The marks still come from the marking scheme, step by step. Read how step marking works in CBSE for that part. For the whole path from the exam hall to the result, see how your answer sheet is actually checked.
Which edition of the rules is this?
The rules above come from the Examination Bye-Laws of 1995, updated to December 2004. It is the edition CBSE publishes in a form that can be opened and read. Class 10 moved to two board exams a year in 2026.
This page found no official notice that changes the fictitious-number rule. It also found none that confirms it for 2026. So it quotes the edition it read, and the date above the page is when the words were checked.
