Grading Scheme:

Cheating and Plagiarism:

Cheating and plagiarism are major academic offences and carry serious penalties.  First offence:  A student caught cheating will receive a mark of “0” “on the work in which the offense occurred”  and have a comment indicating cheating listed on their transcript.  This comment will be removed upon graduation.  Second or subsequent offence:  “The penalty for the second offense of cheating or plagiarism is immediate expulsion from the college for the remainder of the semester or longer, depending on the circumstances.” 2 The comment will remain on the student’s transcript and will not be removed upon graduation.    Students are referred to College Policy on “Cheating and Plagiarism” in the College Academic Policy.
 

Policy on Discrimination/Harassment:

All students and employees have the right to study and work in an environment that is free from discrimination and/or harassment.  Language or activities that defeat this objective violate the College Policy on Discrimination/Harassment and shall not be tolerated.  Information and assistance are available from the Centre of Equity and Human Rights, Room 1185, Seneca@York, 491-5050, ext. 3088.
 
 

 General School Policies and Guidelines:

Submission of Lab Assignments:

All lab assignments must be submitted by the time specified by the faculty.  A penalty of 1 grade level will be imposed for all material submitted late on the day it was due and a further grade level per day will be imposed after one week.  All lab assignments must be properly completed in order to pass the course.

Tests:

The evaluation process through tests is an essential component of the course and therefore attendance at all tests is mandatory.  Any absences must be supported by a legal document within one week.  The faculty must be notified immediately by phone/e-mail in the event of a missed test.  Upon acceptable justification of a missed test the student’s test mark may be based on other methods of evaluation or a supplemental test.

Final Exam:

The final exam must be written at the scheduled time and location.  The faculty must be notified immediately by phone / e-mail in the event of the missed exam and supporting documentation must follow.

Acceptable Documentation:

Proper documentation is required for missed tests and exams.

Punctuality:

Show consideration for your classmates and respect for faculty by arriving on time to class.  If you know in advance of a class that you are going to be late, please let your faculty know.  Please arrive on time for classes so as to minimize disruption to your classmates and faculty.

Cell Phone Usage:

As a courtesy to your fellow students and faculty, cell phones should remain turned off while in class.  If, in the case of an emergency, the cell phone must remain on, please notify the teacher before class begins.

Computing Acceptable Use Policy:

All Students are responsible for abiding by the College’s Computing Acceptable Use Policy and for obeying Provincial and Federal laws/regulations regarding the use of computer equipment, facilities and/or networks.
