Control and Instrumentation 1 (ENGG 0009.1) ? Spring ? 21 ? CW 2 (Assignment 2) ? A ? QP
chances to attend the viva in such cases. It is expected that the student attends the viva
during the first chance itself unless due to extenuating circumstances. If the student does
not attend the viva in spite of being given 2 chances and fails to submit valid reasons,
he/she will be awarded a fail in the module and this shall be counted as a case of academic
integrity violation.
All cases of violation of academic integrity on the part of the student shall fall under any of the below
mentioned categories:
1.
Plagiarism
2.
Malpractice
3.
Ghost Writing
4.
Collusion
5.
Other cases
If the student fails a module and has a proven case of academic integrity violation in this module,
the student is required to re-register the module. This is applicable to first and second offence of
academic integrity violation of plagiarism type
1.1. First Offence of Academic Integrity Violation:
1.1.1. Plagiarism
a. If a student is caught first time in an act of academic integrity violation during
his/her course of study in any assignment other than project work and if the type
of violation is plagiarism, then the student will be allowed to re-submit the
assignment once as per the period allowed for re submission 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 within one
week (5 working days) from the date he or she is advised to re-submit.
c.
Re-submission of the work beyond the allowed period of resubmission will not be
accepted and the assessment will be awarded a zero mark.
d.
If the re-submitted work (within the allowed period of resubmission) is also found
to be plagiarized, then that assessment component will be awarded a zero mark.
It shall also contribute to the total count of academic integrity violation for that
student.

Control and Instrumentation 1 (ENGG 0009.1) ? Spring ? 21 ? CW 2 (Assignment 2) ? A ? QP
e.
If plagiarism is detected in UG Project work (Project 1, Project Planning and Project
Design and Implementation), the above clauses 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 reregister the module.
1.1.2. Malpractice / Ghostwriting / Collusion
If a student is caught first time in an act academic integrity violation during his/her course
of study for an assessment component irrespective of coursework or end semester and
if the type of violation is Malpractice/Ghostwriting/Collusion, then the student shall fail
the module.
1.2. Second Offence of Academic Integrity Violation:
1.2.1. Plagiarism
a. If any student is caught second time in an act of academic integrity violation during
his/her course of study and if the type of violation is plagiarism, then the student
will not be allowed to resubmit the work, and s/he will directly be awarded zero
for the work in which plagiarism is detected.
b.
The student shall also receive a warning of suspension in such cases.
1.2.2. Malpractice/Ghostwriting/Collusion
a. If a student is caught a second time in an act academic integrity violation for an
assessment component irrespective of coursework or end semester and if the type
of violation is Malpractice/Ghostwriting/Collusion, then the student shall fail the
module.
b.
The student shall also receive a warning of suspension in such cases.
1.3. Third Offence of Academic Integrity Violation:
a.
b.
c.
d.
MEC_AMO_TEM_035_02
If a student is caught a third time in an act of academic integrity violation for an
assessment component irrespective of coursework or end semester then the student
shall fail the module and also shall be suspended for one semester from the College,
once the academic integrity violation case is confirmed by Institutional Assessment
Review Committee.

and premises shall cease to exist. The documents shall be released only after getting
the NOC (No Objection Certificate) from Registration Office.
c.
`On termination, the student shall not be refunded any fees paid for the academic
semester in which academic integrity violation was observed.
1.5. Other cases
If a student commits an act of academic integrity violation as per the definition of ?other
cases? mentioned in the previous section or of a different nature, student?s case shall be
forwarded to an Institutional Assessment Review Committee, Chaired by the Associate
Dean, Academic Affairs. The committee shall investigate the case by means of a viva and/or
a hearing of the parties concerned if required and shall take appropriate decision. The
penalty that can be granted to a proven case of academic integrity violation which falls in
this category of ?other cases? can be a warning/component zero/ module
fail/suspension/expulsion depending on the nature and gravity of the offence.
1.6. Types/Variations of cases of Plagiarism and associated actions
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.
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.
If some students in the group are eligible to re-submit (first offence) and others are not
eligible, only eligible students will be allowed to re-submit within a period of one week and
the penalty will be applied as per the policy for each student according to his / her history of
violations.
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.
If some students in the group are eligible to re-submit (first offence) and others are not
eligible, only eligible students will be allowed to re-submit within a period of one week and
MEC_AMO_TEM_035_02

Control and Instrumentation 1 (ENGG 0009.1) ? Spring ? 21 ? CW 2 (Assignment 2) ? A ? QP
the penalty will be applied as per the policy for each student according to his / her history of
violation.
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.
If some students in the group are eligible to re-submit (first offence) and others are not
eligible, only eligible students will be allowed to re-submit within a period of one week and
the penalty will be applied for each student according to his / her history of violation.
b. If plagiarism is detected in the individual assessment component, the individual assessment
component will be resubmitted ? if the student is eligible for resubmission-. 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).
1.7. Types/Variation of Cases of Multiple Offences
If student is caught with multiple violations of same or different nature in different modules
of the same semester, they will be considered as one offence and student will be penalized
for each violation according to the type of the offence.
If student is caught with multiple violations of same or different nature in the same module
of the same semester, then they will be considered as different offences and each will
contribute to the overall count of AIV. The student then shall be penalized for each violation
according to the count and type of each offence.
* For further details Refer to MEC Student Academic Integrity Policy in Student Handbook.
2. Late Submission Regulations:
It is the students? responsibility to check all relevant timelines related to assessments.
As per the Assessment Policy at MEC, late submissions are allowed for one week (5 working days)
for all UG modules with a penalty. In such cases, a deduction of 5% of the marks obtained for the
submitted work shall 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

Control and Instrumentation 1 (ENGG 0009.1) ? Spring ? 21 ? CW 2 (Assignment 2) ? A ? QP
week (5 working days) 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.
