1. You are aware that evaluation is the most important process in the actual and correct assessment of the candidates. 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. Evaluation is a 10-12 days mission for all of us. Hence, it is desired from you to give your best in this process.

2. Evaluation is to be done as per instructions provided in the Marking Schemes. It should not be done according to one’s own interpretation or any other consideration. Marking Schemes should be strictly adhered to and religiously followed. However, while evaluating, answers which are based on latest information or knowledge and innovative maybe assessed and marks be awarded to them.

3. The Head-Examiner must go through the first five answer books evaluated by each evaluator to ensure that evaluation has been carried out as per the instructions given in the Marking Schemes. 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.

4. 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 totalled up and written in the left evaluators.

5. It a question does not have any parts, marks must be awarded in the left hand margin and encircled.

6. If a student has attempted an extra question, answer or the question deserving more marks should be retained and other answer scored out.

Giving more marks to an answer than assigned to it.
Wrong transfer of marks from the inside pages of the answer book to the title page.
Wrong question totalling on the title page.
Wrong totalling of marks of the two columns on the title page.
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 be 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.

11. While evaluating the answer books if the answer is found to be totally incorrect, it should be marked as (X) and awarded zero (0) marks.

12. Any unassessed portion, non-carrying over of marks to the title page or totalling 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.

13. The examiners should acquaint themselves with the guidelines given in the spot evaluation before starting the actual evaluation.

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