Course Policy
ATTENDANCE POLICY:
Regular and punctual attendance is expected of all students in all classes for which they have registered. All absences are considered to be unauthorized unless the student is absent due to illness or emergencies as determined by the instructor. It is the student’s responsibility to provide documentation as to the emergency for approval and judgement by the faculty member. Approved school sponsored activities are the only absences for which a student should not be held liable and only when provided by a school official ahead of the absence. Valid reasons for absence, however, do not relieve the student of the responsibility for making up required work. Students will not be allowed to
make up an examination missed due to absence unless they have reasons acceptable to the instructor. A student who is compelled to be absent when a test is given should petition the instructor, in advance if possible, for permission to postpone the exam. Student will be dropped from a class by the Registrar upon recommendation of the instructor who feels the student has been justifiably absent or tardy a sufficient number of times to preclude meeting the course’s objectives. Persistent, unjustified absences from classes or laboratories will be considered sufficient cause for College officials to drop a student from the rolls of the College. From Board Policy FC (LOCAL) Students may be allowed to drop one exam grade from the required exams given during the course. Required work not completed by due dates will not be accepted without instructor approval.
Course Attendance & Participation are just as important in class as on the job. Any student who is not present will receive a "0" for any graded assignments missed. You may be allowed to make up work, at the instructor’s discretion. If you must be late or absent for any reason you are required to contact the instructor by phone, text or email prior to the absence or tardiness.
You are required to submit online assignments on time regardless of whether or not you are in class that day.
Late assignments will up to 7 calendar days past due with a 5% deduction.
Incomplete assignments will not be accepted.
Cell phone use is prohibited in the classroom and lab unless specifically authorized by the instructor. Earbuds may only be used with specific approval from the instructor.
Class disruptions will not be tolerated.
If you need to leave the classroom or lab for any reason during class hours, inform the instructor of your destination and expected return time. Check back in with the instructor upon your return.
All assignments must be completed by each student individually. There is to be no collaboration unless specified by the instructor.
Dishonesty will not be tolerated. A minor offense will result in a grade of "0" for any assignment affected by dishonest or prohibited behavior. Deliberate, intentional and/or repeated instances of dishonesty such as plagiarism and/or collusion on assignments may result in an “F” for the final course grade or dismissal from the course, and possibly the college at the discretion of the instructor and/or college authorities.
Watches, rings and other jewelry are prohibited in the lab.
Closed toe shoes are required in the lab.
Loose fitting clothing, accessories or any hairstyle that may present a safety issue while using tools are prohibited in the lab.
Outer clothing made from 100% cotton or specific fire resistant material is required to be worn whenever torches are in use in the lab.
Failure to follow any of the above lab policies may result in the student receiving a grade of "0" for any assignment under way at the time. Repeated offenses will result in the removal of the student from the class.
Important Program Notes:
All certificate and degree programs have a capstone exam and lab practical. This capstone process must be completed and passed before NCTC will award the certificate or associates. The exam is often included in the curriculum of the final course each semester but may have to be scheduled with the Division Chair and/or Faculty. If you are completing your final core program course, consider scheduling your capstone.
The instructor may add, remove, or change any graded elements of this course at the instructor's sole discretion.
If you have any questions, please contact your instructor for more information.
LAST DAY TO WITHDRAW
For the fall 2024 semester the last day to withdraw from a course with a “W” is September 14, 2024
STUDENT HANDBOOK
Students are expected to follow all rules and regulations found in the student handbook and published
online.
ADA STATEMENT
NCTC will adhere to all applicable federal, state, and local laws, regulations and guidelines with respect to providing reasonable accommodations to afford equal educational opportunity. It is the student’s responsibility to contact the Office for Students with Disabilities to arrange appropriate accommodations. See the OSD Syllabus Addendum.
AI Statement for Instruction
Absent a clear statement from a course instructor, use of or consultation with generative Artificial
Intelligence (AI) or other similar technologies shall be treated analogously to assistance from another
person, agency, or entity. In particular, using generative AI tools to substantially complete an
assignment or exam is not permitted. Students should acknowledge the use of generative AI (other than
incidental use) and default to disclosing such assistance when in doubt.
When students use generative AI to replace the rigorous demands of and personal engagement with
their coursework, it runs counter to the educational mission of the college and undermines the heart of
education itself. Artificial Intelligence, large language models, and technologies hold promise for
deploying knowledge in service to others and accelerating the discovery of new knowledge. However,
such technology poses new challenges to pedagogy and to integrity. Within the context of the teaching
mission of the college, and consistent with the Student Code of Conduct, the authority to define the
appropriate use, study, and deployment of these technologies rests with the faculty.
Individual course instructors, in coordination with their divisions, set policies regulating the use of
generative AI tools in their courses, including allowing or disallowing some or all uses of such tools.
Course instructors will set such policies in their course syllabi and clearly communicate such policies to
students. Students who are unsure of policies regarding generative AI tools are encouraged to ask their
ACADEMIC DISHONESTY
Scholastic dishonesty shall include, but is not limited to cheating, plagiarism, academic falsification, intellectual property dishonesty, academic dishonesty facilitation and collusion. Faculty members may document and bring charges against a student who is engaged in or is suspected to be engaged in academic dishonesty. See Student Handbook, “Student Rights & Responsibilities: Student Conduct ([FLB(LOCAL)]”.
Consequences for academic dishonesty may include:
A grade of zero on any assignment that the instructor believes was completed dishonestly.
A report of the academic dishonesty to the appropriate authorities at NCTC which may result in removal from the course and/or removal form the college.
DISABILITY SERVICES (Office for Students with Disabilities)
The Office for Students with Disabilities (OSD) provides support services for students with disabilities, students enrolled in technical areas of study, and students who are classified as special populations (i.e. single parents).
Support services for students with disabilities might include appropriate and reasonable accommodations, or they may be in the form of personal counseling, academic counseling, career counseling, etc. Furthermore, OSD Counselors work with students to encourage self-advocacy and promote empowerment. The Counselors also provides resource information, disability-related information, and adaptive technology for students who qualify.
If you feel you have needs for services that the institution provides, please reach out to either Wayne Smith (940) 498-6207 or Yvonne Sandman (940) 668-4321. Alternative students may stop by Room 170 in Corinth or Room 110 in Gainesville.
