Notify your Instructor of faulty wiring/equipment, worn or damaged tools, or missing parts. No horseplay is allowed whatsoever. Academic disciplinary measures will be promptly administered to offending person(s). Please help the Instructor to maintain order so that he can be free to use your time for more effective teaching, and less time housekeeping. We all can enjoy the benefits of an effective and conducive learning environment. Remember to use your safety glasses when entering the shop area. Always perform proper Lock-out / Tag-out.
Tools, Equipment, and Clothing

Tools and equipment specified for this class and any recommended preliminary class in the Nondestructive Testing and Evaluation curriculum are to be furnished by the student.

Stealing, vandalism, or pilferage will be dealt with severely!! No drugs, tobacco, drinks, or food allowed!

Additional Information
Student Conduct/Class Rules
I try to keep a friendly, non-hostile environment in the class. I apply all rules and regulations evenly and fairly.
Attendance
- There are 16 scheduled sessions. The attendance portion of your final grade will be based on 14 sessions. You may miss two sessions without affecting your attendance grade.
- Mid-term and Final exam sessions are not included in the two "no-penalty" sessions you are allowed to miss.
- You will clock in and clock out of each session on the computer in room 107. The time clock entries will be the final word on if you attended class or not.
- Class starts at 6:00 pm. Tardiness will result in loss of attendance points for any session.
- Class ends at 9:50 pm. Leaving early will result in loss of attendance points for any session.
- You are responsible for acquiring notes and homework assignments from fellow students when you are absent.
- Home work is due at the first of the following session after is has been assigned. If you are absent when the assignment was made, it is still due at the following session.
- Failure to turn in homework on time will result in a 20pt reduction on the homework when turned in at the following session. A paper that is two sessions late will receive a grade of 0.
- There are no mid-term or final exam make up tests.
Conduct
- The main thing to remember is to respect each other.
- Cell phones are to be silenced during class. Texting, gaming, taking non-emergency calls, and etc is not permitted. Students who choose not to follow this rule will have the option of surrendering their phone to me for the class or leaving the class for the day.
- It is permissible to bring in food or drinks into the class room. No food or drinks are allowed in the labs or computer labs. If a student does not pick up and properly dispose of food wrappers, cans, and bottles, then the food and drink privilege will be revoked for all students.
- No smoking in the building. There is an area north of the class room that you may smoke during breaks. Use the ash trays and do not throw butts or trash on the grounds or parking lot.
- No chewing tobacco, dip, snuff, sunflower seeds, or anything else that requires a spit cup.
- During class lecture I encourage open discussion; however, when a student asks a direct question to me, I need everyone else to be quite and let me respond. After I have answered the question, anyone wanting to add to or question the answer is welcome to jump in. This fair to all students and will prevent confusion as to what is the proper answer.
- Please be considerate of other classes going on in the building and keep your voices down when you are in the hallways during break.
- Anyone that causes a disruption will be asked to leave the class.
- Bring text book and tools to class every session.
- Infractions of any of the above will result in grade reduction for the day and/or disciplinary action.
