Class and Shop Conduct – Motive Power Policies and Procedures The Heavy Equipment Program considers both HED210-11 Theory and HED211-9 Shop to be co-requisites. Students must successfully complete both courses in the same semester. Motive Power Department Truck/Coach-Heavy Equipment Department Policies and Procedures Policy Information Sheet During your program, you are considered to be a member of the Motive Power Department. As such, your actions and deportment, both in the college and the community reflect on this Department. We trust that your influence will be positive. College policy prohibits the consumption of food and drink in the classrooms and shop. Smoking is allowed only outside of the building in designated smoking areas. No smokeless tobacco is allowed in theory class or shop class. CSA approved Safety Glasses and Safety Boots must be worn in the Shop at all times. This means going to and from all of the classrooms located in the shop. It is the responsibility of the STUDENT to wear them. You will be marked absent if the aforementioned policy is not adhered to. Note; All safety glasses and boots must meet Sault College CSA approval rating. See attachment RE: Eye, Face and Foot Personal Protection Equipment (PPE) NO GLASSES-NO BOOTS-NO ENTRY!! Repairs to your private vehicles in our facilities can be educational to you. We will accommodate you if the work is part of our program and schedules in. No car should be parked in the shop compound without staff permission and a temporary parking pass clearly displayed. Attendance – if late, don’t bother coming until the next class, you will be marked absent. The student is to be continuously present and actively participating during all scheduled theory and shop classes (scheduled breaks excepted). For every unexcused absence you will be deducted 1% per class period missed from that specific unit for the time missed.

The student must have safety boots and safety glasses readily available because you may not have a lot of warning when going into shop.

Please, coffee breaks only 10 to 12 minutes MAXIMUM. NOTE: Individual Professors will address each class with their expectations. Some may only allow 10 minutes.

Please refrain from loitering in “C” wing hallways, around shop hallway entry doors and outside entrance doorways/walkways.

Drinking alcohol or using drugs at lunch is discouraged and students will be excused from class at the Professor’s discretion.

Welding attendance is MANDATORY, as are all related subjects. It is in your best interests to attend all classes on your schedule. Remember, you need to successfully complete all assigned courses to graduate.

If you miss a test with an “unexcused absence” (as deemed legitimate by your professor) you will NOT be allowed to write that test. Only if; a doctors note, airline ticket, etc., or circumstances arising from a family emergency; and legitimate written proof can be presented to the professor. See item number 16 below for clarification.

If a class is missed or going to be missed it is your responsibility to notify in writing (see item #16 below) your Professor and make arrangements for handouts and notes taken while you are away.

The use of cell phones/PDA’s, electronic information/image capturing or recording device for any form of communication or recording (voice, text, recording, image, etc…) during theory class or shop is strictly prohibited. Cell phones/PDA’s must be silenced during regular class and shop times and must be turned off and kept out of sight during all classes and test sittings. Failure to follow the latter requirement during a test sitting will result in a grade of 0 (zero) being assigned and if not out of sight or being used during class, the unit WILL be confiscated for the duration of the class.

NO EXCEPTIONS

14.	Students may not wear earphones/headphones of any kind (i.e. for playback of recorded music/voice) during theory classes, shop classes and test sittings. This does not include hearing aids as required by hearing impaired students.

15.	NO Lap Top Computers will be allowed in any class unless proper documentation is provided that the computer is required for learning assistance.

16.	Any request to deviate from the aforementioned course outline requirements must be made to the Professor in writing or via Sault College email. If permission is granted it must also be granted in writing or via Sault College email. Verbal requests/permissions are not acceptable. It is the student’s responsibility to maintain a copy of all such requests and associated permissions.

ATTENDANCE

A terminal objective of the Motive Power Department is the demonstration of satisfactory attendance and punctuality performance that the Motive Power Industry, itself, relies on, for efficiency, productivity and profitability.

Absences will affect your learning and your final grade.

Students are encouraged to be present for the full duration of each class. Shop attendance is recorded at the start and end of class. Students are expected to be continuously present and actively participating (scheduled breaks excepted) for the entire class.

If you are absent from class at the time of attendance, you will be marked absent from the entire class.

1.3	If you are marked absent, and no reasonable excuse is given your absence will be termed unexcused. There should NOT be a reason to NOT let us know nor related subject Professors, in writing why you’re absent.

1.4	Students will lose marks from their theory and shop mark grade for unexcused absences. Poor attendance can mean a repeat of both theory and shop courses if your employment skills are poor. This is based on the 10% Employability Skills.

1.5	At 10% of accumulated hours of unexcused absence you will be asked to a scheduled meeting with your Professor and will be asked to sign a contract enabling you to continue the course.

1.6	If you are absent from class, the lesson material is your responsibility.
