General Instructions :-
1. You are aware that evaluation is the most important process in the actual and correct 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 teaching profession. To avoid mistakes, it is
requested that before starting evaluation, you must read and understand the spot evaluation
guidelines carefully.
2. “Evaluation policy is a confidential policy as it is related to the confidentiality of the
examinations conducted, Evaluation done and several other aspects. Its’ leakage to the 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 News Paper/Website etc may invite action under IPC.”
3. 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 evaluating answers which are
based on latest information or knowledge and/or are innovative, they may be assessed for
their correctness otherwise and marks be awarded to them. In class-X, while evaluating two
competency based questions, please try to understand the given answer and even if the reply
is not from the marking scheme but correct competency is enumerated by the candidate,
marks should be awarded.
4. 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. The remaining answer books meant for evaluation shall be given only after
ensuring that there is no significant variation in the marking of individual evaluators.
5. Evaluators will mark ( √ ) wherever the answer is correct. For wrong answer ‘X’ be marked.
Evaluators will not put the right kind of mark while evaluating which gives an impression that the
answer is correct and no marks are awarded. This is the most common mistake which
evaluators are committing.
6. If a question has parts, please award marks on the right-hand side for each part. Marks awarded
for different parts of the question should then be totalled up and written in the left-hand margin
and encircled. This may be followed strictly.
7. If a question does not have any parts, marks must be awarded in the left-hand margin and
encircled. This may also be followed strictly.
8. If a student has attempted an extra question, the answer of the question deserving more marks
should be retained and the other answer scored out.
9. No marks to be deducted for the cumulative effect of an error. It should be penalized only once.
10. A full scale of marks 25 (example 0-25 marks as given in Question Paper) has to be used. Please
do not hesitate to award full marks if the answer deserves it.
11. Every examiner has to necessarily do evaluation work for full working hours i.e. 8 hours every day
and evaluate 30 answer books per day in main subjects and 35 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 the question paper.
12. Ensure that you do not make the following common types of errors committed by the Examiner in
the past :-
● Leaving the answer or part thereof unassessed in an answer book.

Marking Scheme - Computer Applications Subject Code 165 Paper Code 53 2022 PAGE: 1/11

● Wrong grand total.
● Marks in words and figures not tallying.
● Wrong transfer of marks from the answer book to online award list.
● 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
answers.)
● Half or a part of the answer marked correct and the rest as wrong, but no marks awarded.

13. 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.

14. Any unassessed portion, non-carrying over of marks to the title page, or totaling error detected
by the candidate shall damage the prestige of all the personnel engaged in the evaluation work as
also of the Board. Hence, in order to uphold the prestige of all concerned, it is again reiterated
that the instructions be followed meticulously and judiciously.

15. The Examiners should acquaint themselves with the guidelines given in the Guidelines for spot
Evaluation before starting the actual evaluation.

16. Every Examiner shall also ensure that all the answers are evaluated, marks carried over to the
title page, correctly totaled and written in figures and words.

17. The Board permits candidates to obtain a photocopy of the Answer Book on request in an RTI
application and also separately as a part of the re-evaluation process on payment of the
processing charges.
