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 will 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 not be accepted.
  • 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 will result in removal from the class, course or 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 Note – 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 has to be scheduled with the Division Chair and/or Faculty.  If you are completing your final core program course, consider scheduling your capstone.  If you have any questions, please contact your instructor for more information

 

LAST DAY TO WITHDRAW 

For the fall 2020 semester the last day to withdraw from a course with a “W” is September 26, 2020

 

STUDENT HANDBOOK

Students are expected to follow all rules and regulations found in the student handbook and published online.

Potential Conversion of Onsite Classes to Online/Remote Format: North Central Texas College students should be aware that in the event of a college closure due to COVID-19, onsite classes will be converted to an online/remote format. Students should plan ahead to ensure they have access to the computer equipment (either PC, MAC, or tablet), webcam, and internet connectivity to continue their classes in an online/remote format. Please read all your official North Central Texas College student emails as the transition from onsite to online/remote might require a reorganization in your personal situation. Students will be granted a 72-hour transition and grace period. Online classes will continue as scheduled without disruption. Wear a mask, stay safe, and contact your Instructor as the situation arises. These policies and procedures were updated on July 30, 2020 and are subject to change.

Face Coverings: Per the North Central Texas College guidance on face coverings on campus, in the instructional setting, faculty and students must wear face coverings, such as masks or face shields. Students without coverings, or those who do not comply with the rules relating to face coverings, will not be able to participate in on-campus classroom activities. To request an exception to this requirement, students should contact the NCTC HR Office of Enrollment Management (ccove@nctc.edu). Failure to comply with the face coverings requirement may result in the Instructor directing the student to leave the classroom. Any student asked to leave the classroom may be referred to the student conduct officer. These policies and procedures were updated on July 30, 2020 and are subject to change.

Temporary COVID-19 Attendance Policy for Face-to-Face Meetings: We are facing an unprecedented situation in which all of us must be flexible and make prudent decisions in the best interest of our families, our campus, and our community. In light of this, North Central Texas College is temporarily establishing the requirement that faculty keep records of student attendance for face-to-face course meetings as well as a documented seating chart. In addition, students who are sick or need to quarantine should not attend classes. Students will not be required to provide formal documentation from a health care provider and will not be penalized for COVID-19 related absences when proper notification to campus health officials is made in accordance with the guidelines stated below.

Faculty will:

  • Notify students about important course information and delivery changes through Canvas and campus email.

Students should:

  • Provide notification to campus officials (via NCTC Daily Health Check protocol through Canvas) if they have tested positive for COVID-19 or have to quarantine so we can confirm reported absence with instructors, monitor, and assist the campus community.
  • Notify instructors in advance of the absence.
  • Connect with that class through Webex if the class session is being transmitted in a hybrid fashion.
  • Keep up with and/or make up missed classwork or assignments.
  • Submit assignments digitally through Canvas or other means as announced by your instructor.
  • Work with their instructors to reschedule exams, labs, and other critical academic activities described in the course syllabus.
  • Check Canvas and campus email daily to receive important announcements pertaining to the course.

During this period, faculty with face-to-face meetings will establish assigned seating/work stations to facilitate roll-taking, and, if necessary, contact tracing. Additionally, we ask all members of the College community to be attentive to their health, and safeguard others, by following the CDC’s guideline to “stay home when you are sick.” You should stay home if you have symptoms. More information on what to do if you are sick is available at the CDC’s website.

Additional NCTC information is available at http://www.nctc.edu/coronavirus/index.html (Links to an external site.)

 

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:

  1. A grade of zero on any assignment that the instructor believes was completed dishonestly.
  2. A report of the academic dishonesty to the appropriate authorities at NCTC  which may result in removal from the course and/or removal from 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.
