Tests, Quizzes, Homework
Attendance and Attitude
Final Exam (written)
Total Possible
Class Grade Percentage
50%
25%
10%
15%

Lab Points awarded per completed assignment
85%-100%= A
76%-84%= B

50%-64%= D
Instruction: The class with be taught in active rather than active manner and will
require your participation in the discussions. Please read the material ahead of time so that
you have the background or at least some understanding what we are talking about. Feel
free to ask guest ions on subject matter only.
Written Tests: Success in welding is primarily your ability to actually weld. Therefore,
a major portion of your course grade will be derived from your performance in the
welding booth as assignments. The remainder of the grade will be on the written tests
taken throughout the semester (see dates on schedule handout), the comprehensive final
test, unannounced pop quizzes (no make-up), and homework. All questions on the tests
will be material that is covered in the classroom. It is important that you take notes and
study all handouts.
Attendance: Regular attendance in a punctual manner is essential for success in this
class as well as the work place. Attendance roll will be taken daily. On your third absence,
you will be given a warning and on your fifth absence your status in the class will be
evaluated, and you may be dropped from the course. Excessive unexcused absences will
be reflected on your final grade at the discretion of the instructor. There in a change for the
last day you can add and drop that is Sunday Sept. 2 without a W. If you enrolled and if
you drop the class you must contact records and remove your self from the class roster.
Failure to remove ones self will result in an “F” on final grade sheet. You have up to the
12-week to withdraw with a “W” after that it is an automatic “F” from the college.

Student Conduct: Students are expected to conduct themselves in a manner that is
appropriate for college classroom and lab. There is defiantly no “horse play” in the shop
portion of this class. Basic expectations include arriving on time, listening while the
instructor or another student is talking, actively participating in classroom discussions, and
working in a professional manner in the lab portion.

*The Cuesta College Welding Program has identified the above SLO’s as applicable to
the WELD 270c –MIG and TIG course.
RECOMMENDATIONS/EXPECTATIONS:
1. Safety – All students must pass the Welding Safety test with 100% accuracy.
Everyone is required to wear safety glasses and appropriate personal protective
equipment at all times in the shop. Anyone reporting to the shop without
proper safety attire and/or equipment will be instructed to leave.
2. Clean Up – You are responsible for cleaning up your work area, as well as
making a general contribution to leaving the shop in an orderly state (sweeping
floor, picking up waste, turning machines off, etc.). You must leave enough
time to do this before the class is over.
3. Welding Booths – No one owns a welding booth. Your welding station is on a
first come first serve basis. Please help us maintain it report any problems to
the instructor.
4. Text and Materials – You will be given text material and be required to
organize and maintain a class binder for test and reference use. There will be
locations on the Internet where you will be required to access.
5. Lockers – You will have the opportunity to utilize a locker in the shop.
See the instructor to obtain a locker. You will need to provide your own lock.
6. Parking – The shop compound is not for student/staff parking. We must
utilize the appropriate parking areas outside the compound. Don’t try to get by
without purchasing a parking permit. It is a good financial investment.
7. Disabilities / Special Needs - If you are a student with a verified disability,
please make an appointment with me to discuss your needs for
accommodations as soon as possible.
8. Academic Honesty – You will earn your instructors and peers respect by your
honesty (see the Academic Honesty Policy in your class schedule).

9. Cell Phones – Please turn off your cell phones during class time.
10. Projects – Class time and space constraints prevent this course from being a
project construction class. The Welding 270C course is designed to provide
you with the skills to build projects out of class or during our WELD 277
course.
Office hours are by arrangement only. Part time instructors are not required to list and have a
place to do paper work on campus. For any reason, you cannot attend class, please call and leave a
message on my cell phone 459-3001. Your attendance counts toward your grade.
