    GM ASEP Time Clock Procedures

    In order to maximize learning in the GM ASEP Program, students are required to “clock in” at or before the beginning of each class session and to “clock out” upon class dismissal, each day. Students are also required to “clock out” and “clock in” at break time. Students found to be dishonest in this procedure, in any way, will be recommended for ASEP Program withdrawal. Because of the extreme importance that the automotive industry places upon being punctual, dependable, and reliable, the student will punch a time card at break or at the beginning or at the end of each class session. A daily total of 4 points will be available for the attendance grade, two points for the morning session and 2 points for the afternoon. In order to receive full credit for attendance all time punches must be made at or before the session start time. One point will be deducted for any time punch after the session start time and up to 5 minutes late, no points will be awarded after the five minute grace period. The same time punch policy will apply to the morning break time. When a student does not report back to class after break or after lunch, 2 points will be deducted from the students weekly attendance grade for those infractions. Please note the applicable grading procedure stated above. In addition, students who are more than 5 minutes tardy may not be allowed into the classroom after the class session has begun.

    ASEP Absentee Reporting

    When unavoidable circumstances make attendance impossible, students must provide a satisfactory explanation of their absences to the ASEP instructor. In every possible case, the instructor must be informed of the necessary absences a minimum of two school days before they occur. In the case of emergency absence or illness, it is the student’s responsibility to inform the instructor of the situation as soon as possible. This should be done before the class to be missed starts if it is physically possible for the student or an acquaintance to do so (the office voice mail will take messages at any time of the day 575-492-2863). You may also reach me or leave a voice mail on my cell phone which is 575-441-2800. It is the responsibility of the student to request and make up all work missed during the absence. In some instances, the student may not be allowed to make up missed work at the discretion of the instructor (see Make-up Policy below). For all absences, regardless of the cause, either before the absence or immediately upon returning to class the student must provide the instructor printed/written evidence explaining the absence(s). Examples of such evidence include a doctor’s excuse, court documents, funeral notice, etc.

    ASEP Excessive Absences

    Due to the accelerated nature of the ASEP Program, students that exceed two (2) absences in any core course during the semester will be recommended for withdrawal from the ASEP program. In cases of emergencies and illness, students need to follow the procedures provided below.

    ASEP Make-up Policy - This policy applies to both excused and unexcused absences.

    Students should remain out of class only when absolutely necessary, much of the classroom and laboratory activity cannot be made up; the benefit of lectures, discussion, and participation is lost forever to those who are absent.

    Upon returning to class after an absence, it is the student’s responsibility to request any assignments missed. Additionally, all work turned in late will lose 10 percentage points for each day it is late. There will be NO opportunity to make up missed quizzes and tests due to tardiness; a “0” will be recorded. Exceptions will be considered only for extreme circumstances.


    Students will be held responsible for the information on these pages.

    Academic Honesty
    Each student is expected to maintain the highest standards of honesty and integrity in online academic and professional matters. The College reserves the right to take disciplinary action, up to and including dismissal, against any student who is found guilty of academic dishonesty or otherwise fails to meet these standards. Academic dishonesty includes, but is not limited to, dishonesty in quizzes, tests, or assignments; claiming credit for work not done or done by others; and nondisclosure or misrepresentation in filling out applications or other College records. Cheating or gaining illegal information for any type of graded work is considered dishonest and will be dealt with accordingly.

    Americans with Disabilities Act (ADA) Information
    Any student requiring special accommodations should contact the Special Needs Student Services Coordinator at (575) 492-2576 or by e-mail at

    Attendance Policy
    Attendance is required at every session of each course for which the student is enrolled. When unavoidable circumstances make attendance impossible, students must provide a satisfactory explanation of their absences to their professors. College-sponsored activities are considered excused absences and the appropriate sponsor of those students who will be absent from class will notify professors. Students having absences due to college-sponsored activities will need to make arrangements with the affected classes / professor to take care of required work; however, arrangements for make-ups should be made within a reasonable time frame, usually within one week of the absence. Regarding make-up work, absences due to late registration are considered the same as regular absences.

    Cell Phones/Pagers
    All cell phones and pagers must be turned off when the student is participating in any lecture, laboratory, or other learning activity.

    Classroom Conduct
    The professor is responsible for maintaining a class environment best suited for effective learning. By registering for this class, the student is assumed to have entered into an agreement with New Mexico Junior College and the professor to attend the class regularly and to behave in an appropriate manner at all times. Disruptive behavior may result in the student being removed from the class.

    Food and Drink Policy
    Food items and soft drinks may not be consumed in NMJC classrooms. Students are also discouraged from bringing food and drink items into the classroom even though these items remain in sealed packaging. Bottled water is permissible.

    No Children in the Classroom
    In order to adhere to instructional procedures as well as maintain the safety of children, NMJC’s policy of no children in the classrooms (lecture, lab, etc.) will be followed.

    Offering the work of another as one’s own, without proper acknowledgment, is plagiarism; therefore, any student who fails to give credit for quotations or essentially identical expression of material taken from books, encyclopedias, magazines and other reference works, or from the themes, reports, or other writings of a fellow student, is guilty of plagiarism. Plagiarism violates the academic honesty policy and is considered cheating.

    Smoking/Use of Tobacco
    New Mexico Junior College is cognizant of the health hazards associated with smoking / use of tobacco for the smoker, as well as the non-smoker. In an effort to provide a healthy environment for students, employees, and others who may frequent the campus, NMJC prohibits smoking / use of tobacco inside any campus building or facility.

    Tutoring Assistance
    Free tutoring services are available to all NMJC students through Brainfuse and the Academic Success Center located at the Pannell Library on the 1st floor.

    Withdrawal Policy
    Regular, punctual attendance is required for all classes at NMJC. Although the professor has the right to drop any student who has missed the equivalent of 2 weeks of instruction (based on a 16 week semester) whether it’s a face to face, online, or a hybrid course, it is not guaranteed that the professor will drop the student. If the student chooses to stop attending a class, he/she should withdraw from the class by accessing your student account in the T-Bird Web Portal at, or submitting the required paperwork to the Registrar’s Office by 5:00 p.m. on Friday, February 22, 2019. All students are encouraged to discuss their class status with the professor prior to withdrawing from the class.
