Attendance Policy

Tardiness- Any tardiness will be considered to be one (1) hour absent.  Any student(s) that are not in their assigned areas at the appointed times whether at the beginning or the end of the class period will be counted as tardy.  This includes leaving early for breaks, lunch or at the end of the day.

Absences- The Medium and Heavy Truck Technology Department strives to teach employability skills as well as technical skills.  Attendance is an important part of learning as well as a success factor in today’s workplace.  Participation in assignments and projects help develop a variety of skills and is vital to the total education of the student.  Regular and prompt attendance is expected in all courses and is necessary in maintaining acceptable grades.  Students who are late for a class or who leave class early will be counted absent for one hour or the whole class, whichever is greater.  Students who miss more than 18 excused/and or unexcused hours in one semester will be subject to dismissal and will not receive credit for that semester.  Absences due to extenuating circumstances may be excused at the discretion of the instructor.

Course Progression
Students must maintain a 70% (2.0) grade in each course of the diesel curriculum.  If a student makes below a 70% (2.0) grade in any course, the student will be required to retake the entire diesel curriculum the following semester; however, students who earned a passing grade in Technical Communications I,   Technical Communications II, or Technical Mathematics I will not be required to take those courses.  If the student retakes the courses within the curriculum, the grades earned in the retake semester will replace the previous semester, even if a higher grade was earned in the course the first time the student took the course.
