Plagiarism Policy:
As per MEC policy, any form of violation of academic integrity will invite severe penalty. Plagiarised
documents, in part or in whole, submitted by the students will be subject to this policy.
A. First offence of plagiarism
a. If a student is caught first time in an act of plagiarism during his/her course of study in any
assignment other than project work, the student will be allowed to re-submit the assignment
once, within a maximum period of one week. However, a penalty of deduction of 25% of the
marks obtained for the resubmitted work will be imposed.
b. Period of re-submission: The student will have to re-submit the work one week from the date
he or she is advised to re-submit.
If the re-submitted work is also found to be plagiarized, then the assessment will be awarded a
zero mark
d. Re-submission of the work beyond the maximum period of one week will not be accepted and
the assessment will be awarded a zero mark.
e. If plagiarism is detected in Project work (Project 1, Project Planning and Project Design and
Implementation) the above clauses (a,b,c,d) do not apply and the work will be summarily rejected.
In these cases the student will be awarded a fail (F) grade and is required to re-register the module
f. If the student fails the module and has a proven case of academic integrity violation in this
module, the student is required to reregister the module

B. Second offence of plagiarism
a. If any student is caught second time in an act of plagiarism during his/her course of study (in a
subsequent semester), the student will directly be awarded zero for the work in which plagiarism
is detected. In such cases, the student will not be allowed to resubmit the work.
b. If the student fails the module and has a proven case of academic integrity violation in this
module, the student is required to re-register the module
C. Third Offence of plagiarism
If any student is caught for the third time in an act of plagiarism during his/her course of study (in
a subsequent semester), the student will be penalized with a fail in the module and shall be
required to re-register the module.
D. Fourth Offence of plagiarism
If any student is caught for the fourth time in an act of plagiarism during his/her course of study
(in a subsequent semester), the student shall be suspended from the College for a period of one
semester.
E. Fifth offence of plagiarism
If any student is caught for the fifth time in an act of plagiarism during his/her course of study (in
a subsequent semester), the student shall be expelled from the College
Types/Variations of cases of Plagiarism and associated actions
A. Type 1: In case plagiarism is detected in any component or part submission (submitted at
different times) of one assessment (assignment), the deduction in marks will be
applicable for the whole assessment (assignment), even if only the component or part
submission alone needs to be resubmitted.
B. Type 2: In case plagiarism is detected in a group assessment, all students of the group will
be considered as having committed an act of plagiarism irrespective of whether
plagiarism is on account of the act of all or a few or only one member. The policy will then
be applied to all students.
C. Type 3: Combination of Type 1 and Type 2: In case plagiarism is detected in any
component or part submission (submitted at different times) of a group assessment
(assignment), the deduction in marks will be applicable for the whole assessment
(assignment), even if only the component or part submission alone needs to be
resubmitted. All students of the group would be considered as having committed an act
of plagiarism irrespective of whether plagiarism is on account of the act of all or a few or
only one member. The policy will then be applied to all the students of the group.
D. Type 4: Variation of Type 1 and Type 2: In cases where the assessment consists of
components or part submissions that could be a group assessment component (e.g. group
assignment) and an individual assessment component (e.g. individual reflection), the
following will be applicable:

a. If plagiarism is detected in the group assessment component, all students of the
group will be considered as having committed an act of plagiarism, irrespective
of whether plagiarism is on account of the act of all or a few or only one member.
The policy will then be applied to all students of the group. In such cases the group
assessment component will be resubmitted as per the policy.
b. If plagiarism is detected in the individual assessment component, the individual
assessment component will be resubmitted as per the policy. The policy will then
be applied to that student alone.
c. In both cases (a) and/or (b), the deduction in marks will be applicable for the
whole assessment (assignment).
Rules & Regulations

If any part of assignment is found copied from the other then marks will be deducted accordingly.

Assignments with 3 or more identical topics will be awarded 0 Marks.
Late Submission Policy
The recommended practice at MEC is to set the cutoff time to 23:59 on the due date for all
assessment submissions. As per the Assessment Policy at MEC, for any late submissions, a penalty
of deduction of 5% of the marks obtained for the resubmitted work will be imposed for each
working day following the last date of submission till the date of actual submission. Assessment
documents submitted beyond a period of one week after the last date of submission will not be
accepted and will be awarded a zero for that assessment. In cases where the submission has been
delayed due to extenuating circumstances, the student may be permitted to submit the work
without imposing the late submission policy stated above. The extended period of submission will
be one week from the original last date of submission. In such cases, the student is expected to
submit the supporting certificates on or before the original last date of submission of the
assessment and the decision of extension rests with faculty responsible for the assessment .The
late submission policy shall be applied if the student fails to submit the work within one week of
the original last date of submission.
Students may contact their teachers for clarification on specific details of the submission time if
required.
