1 The CBSE has decided to introduce On Screen Marking (OSM) for the evaluation of
Class XII answer Book with the 2026 Examination.
m
.co
2 You are aware that evaluation is the most important process in the actual and correct
m
.co
assessment of the candidates. A small mistake in evaluation may lead to serious
problems which may affect the future of the candidates, education system and
e m
em l
teaching profession. To avoid mistakes, it is requested that before starting evaluation,
as
as
you must read and understand the spot evaluation guidelines carefully.
l a g
3 g
“Evaluation
aofleakage
policy is a confidential policy as it is related to the confidentiality
the examinations conducted, evaluation done and several other aspects. Its
to public in any manner could lead to derailment of the
examination system and affect the life and future of millions of candidates.
Sharing this policy/document to anyone, publishing in any magazine and
printing in Newspaper/Website, etc. may invite action under various rules of
the Board and IPC.”
4 Evaluation is to be done as per instructions provided in the Marking Scheme. It should
not be done according to one’s own interpretation or any other consideration. Marking
Scheme should be strictly adhered to and religiously followed. However, while
m
.co
evaluating, answers which are based on latest information or knowledge and/or
are innovative, they may be assessed for their correctness otherwise and due

e m
marks be awarded to them. In Class-XII, while evaluating two competency-

las
based questions, please try to understand given answer and even if reply is not

due marks should be awarded. ag
from marking scheme but correct competency is enumerated by the candidate,

5 The Marking scheme carries only suggested value points for the answers.
These are in the nature of Guidelines only and do not constitute the complete answer.
The students can have their own expression and if the expression is correct, the due
marks should be awarded accordingly.
6 The Head-Examiner must go through the first five answer books evaluated by each
evaluator on the first day, to ensure that evaluation has been carried out as per the
instructions given in the Marking Scheme. If there is any variation, the same should
be zero after deliberation and discussion. The remaining answer books meant for
m
.co
evaluation shall be given only after ensuring that there is no significant variation in
m
c. o7
the marking of individual evaluators.
Evaluators will mark ( √ ) wherever answer is correct. For wrong answer CROSS ‘X’
e m
e m be marked. Evaluators will not put right (✓) while evaluating which gives an
l as
las ag
impression that answer is correct and no marks are awarded. This is most common

ag 8
mistake which evaluators are committing.
If a question has parts, please award marks on the right-hand side for each part in
the OSM Portal. Marks awarded for different parts of the question will be totaled up
by the OSM System.
9 If a question does not have any parts, marks must be awarded in the left-hand margin
in the OSM Portal. This may also be followed strictly.

10 No marks to be deducted for the cumulative effect of an error. It should be penalized
only once.
11 A full scale of marks ____60______ (example 0 to 80/70/60/50/40/30 marks as given
in Question Paper) has to be used. Please do not hesitate to award full marks if the
answer deserves it.
12 Every examiner has to necessarily do evaluation work for full working hours i.e., 8
hours every day and evaluate 20 answer books per day in main subjects and 25
answer books per day in other subjects (Details are given in Spot Guidelines). This
is in view of the reduced syllabus and number of questions in question paper.
13 Ensure that you do not make the following common types of errors committed by the
Examiner in the past: -
● Answers marked as correct, but marks not awarded. (Ensure that the right tick
mark is correctly and clearly indicated. It should merely be a line. Same is with
the X for incorrect answer.)
● Half or a part of answer marked correct and the rest as wrong, but no marks
awarded.
14 While evaluating the answer books if the answer is found to be totally incorrect, it
should be marked as cross (X) and awarded zero (0) Marks.
15 The Examiners should acquaint themselves with the guidelines given in the
“Guidelines for Spot Evaluation” before starting the actual evaluation.
16 The candidates are entitled to obtain photocopy of the Answer Book on request on
payment of the prescribed processing fee. All Examiners/Additional Head
Examiners/Head Examiners are once again reminded that they must ensure that
evaluation is carried out strictly as per value points for each answer as given in the
Marking Scheme.
17 If a candidate attempts both alternatives/options in a question where only one
option/ alternative is required to be attempted, the Evaluator shall award marks
in both the options. The system will take the higher of two scores and
disregard the other response.
18 In a question having two options/alternatives, if a candidate has attempted only
one, then the evaluator shall mark “NA” (Not attempted) against the option that
has not been attempted by the candidate.
