GRADING SYSTEM

All class grades will be posted in Blackboard.  You can check on your progress and see up to date grading in your Grade Center in Blackboard.

Attendance:         0%

I will keep track of late arrivals and early departure times. These times will be accumulative for your 10 hours of class time that you can miss before you must drop or be dropped. You can miss no more than 2 classes and still achieve a passing grade. Once you’ve missed 3 classes, you must drop!!!
 

Assessments/Exams: 40%

Tests will be the Midterm & Final. The Midterm will have two attempts. The first will be taken with no resources and the second will be open book. The two attempts will be averaged together for your midterm test grades. All test will be taken in class. Final test will be closed book with one attempt
 

The final exam will test your knowledge of the fundamentals that you must know to be successful in the next level courses and the automotive industry. This exam will include ASE style questions as well as a hands-on portion.
 

Shop/Classroom Participation & Tools: 20%

This grade is based upon your bringing tools, books, and supplies to every class, your participation in shop work, lectures, and class discussions, and cleaning up after yourself at the end of each class. All vehicles worked on will have an estimate created by the student on “Direct Hit”. This includes wearing safety glasses while in the shop. 10 points will be deducted from daily shop grade every time I have to ask a student to put safety glasses on.

Safety Test:  5%

The safety test will be given during the beginning of the semester. This test will count for 5% of your final grade. You must complete your safety test before you are allowed to work in the shop area.
 

Homework: 20%

You will be required to complete assignments for each chapter and assigned modules from Electude. This will count for 20% of your total grade.
 

ASEEF Task Tracking:  5%

For all completed shop projects, work orders, worksheets, etc., each student is required to log into the Google Sheet and document the NATEF tasks that were completed each class. NATEF Tracking counts for overall grade for this course. You will also be required to print your NATEF task report and include it in your folder.

Post Test:          10%
 

You will be given a pre/post-test for this course. The pre-test will not count as a grade but as to determine what is needed to make the class a success. The post-test will count 10% of your total grade. It is the exact same test taken at the beginning and end of the class.

THE GRADING SCALE:

                               90-100 A

80-89   B

                                         70-79   C

60-69   D

0-59  F

COURSE POLICIES
 

1. Regular attendance is required. Only limited absences and tardies will be accepted if a grade better than a "D" is expected. *(1C-1, 4, 2A-4)
 

2. Students are required to maintain a "C" average, or a grade point average of 2.00. This means that the average of all classes must be a "C" in order to obtain either a certificate of completion, or degree. Students who either arrive late for class, leave early, and/or bring no tools cannot expect to complete lab assignments in a timely manner and receive a grade better than "D". For further information, see the sections on "graduation" and "Academic Suspension" in the Administration Information area of the current ACC Catalog. *(1A-1, 1C-1, 2, 4, 5, 2A-4)
 

3. Students are expected to purchase their own tools. A list of the minimum type and number of tools are furnished at the beginning of each semester. Each student will have his/her own tools available for shop work at beginning of each class period. Loaning or borrowing of tools between students is discouraged. Specialty tools, tools not on the student tool list, are available from the Tool Room. The college will furnish tools for students who are enrolled in the Introduction to Automotive class. Failure to bring tools after the first month of enrollment in the Automotive Program subjects each student to disciplinary action up to and including dismissal from the program.*(1C-5, 2A-2)
 

4. Safety is always first. Common sense and our certifying agency, NATEF, require that all students wear safety glasses in the shop. Students without safety glasses will be prohibited from any shop activities.*(1C-2, 4, and 5)
 

5. Each student is strongly encouraged to participate in class. In any classroom situation that includes discussion and critical thinking, there are bound to be many differing viewpoints. These differences enhance the learning experience and create an atmosphere where students and instructors alike will be encouraged to think and learn. On sensitive and volatile topics, students may sometimes disagree not only with each other but also with the instructor. It is expected that faculty and students will respect the views of others when expressed in classroom discussions.
 

6. By applying to and registering at Austin Community College, students agree to abide by the Student Discipline Policy and Student Rights and Responsibilities regulations published in the ACC College Catalog and this Student Handbook. Acts prohibited by the college for which discipline may be administered include student profit associated with any lab project, scholastic dishonesty, including but not limited to cheating on an exam or quiz, plagiarizing, and unauthorized collaboration with another in preparing outside work. Academic work submitted by students shall be the result of their thought, research or self-expression. Academic work is defined as, but not limited to tests, quizzes, whether taken electronically or on paper, projects, either individual or group; classroom presentations, and homework.  Prohibited acts include disruptive conduct of any kind. Disruptive conduct is defined as, but not limited to:  Behavior that significantly interferes with or disrupts any ACC teaching, research, administrative, disciplinary, public service or other authorized activity. Behavior that threatens the health or safety of members of the ACC community, visitors to ACC, or participants at ACC-sponsored events, or willful negligence in the performance of lab projects. The minimum penalty for violation of these policies is a grade of "F" for the course.
 

7. Each ACC campus offers support services for students with documented physical or psychological disabilities. Students with disabilities must request reasonable accommodations through the Office for Students with Disabilities on the campus where they expect to take the majority of their classes. Students are encouraged to do so three weeks before the start of the semester.

TOOL POLICY:

After the first day of class, students must bring their tools to class every day. If you fail to bring your tools you cannot complete the shop tasks. Students must bring all the tools listed on the tool lists every day to class. Borrowing of tools is discouraged.

AUTOMOBILES FOR SHOP WORK:

Although vehicles are always needed for shop work, whose car and which car is worked on first is not considered to be an important part of the course. All cars to be worked on in the shop must first be approved by the instructor. Even though emergencies occur with cars breaking down, we are not here to schedule work as a garage would. Time schedules will not be considered or given as related to repair work of any given automobile. Only work related to the course will be considered. No work will be performed on a car if the subject has not yet been covered in the classroom, unless authorized by the instructor.

CARE AND CLEANING OF TOOLS, EQUIPMENT, AND THE SHOP AREA:

All students will be expected to participate in shop and classroom cleanup at the end of each class period. Sufficient time will be allotted by the instructor for this purpose. All tools will be cleaned and put in the proper place before class will be dismissed.

ASEEF:

The Automotive Service Excellence Education Foundation (ASEEF) is the responsible body for the Automobile Technician Training Certification Program. The certification program is under the direct supervision of the board of trustees of The National Automotive Technician Education Foundation (ASEEF). The purpose of the Automobile Technician Training Certification Program is to improve the quality of training offered at the secondary and post-secondary level. ACC is currently certified in all automotive areas.

Attendance/Class Participation

The College System believes that regular attendance in all classes is necessary and makes no distinction between excused and unexcused absences. I will personally excuse within reason and at my discretion. This applies only to the number of absences counted towards dropping a student, not daily/shop grades.

Withdrawal Policy
Students may be dropped from a course after accumulating absences in excess of 12.5% of the total hours of instruction (lecture and lab). For a 4 credit-hour lecture/lab course meeting 5 hours per week (80 hours of instruction), you can be dropped after 10 hours of absence. Administrative drops are at the discretion of the instructor. Failure to withdraw officially may result in a grade of F in the course. Do not expect the instructor to drop you! Students can also be dropped for Lack of progress, missed test/assignments, lack of pre-requisite, unprofessional behavior, horse play, safety violations, and any chemical influence.

It is the responsibility of each student to ensure that his or her name is removed from the rolls should they decide to withdraw from the class.  The instructor does, however, reserve the right to drop a student should he or she feel it is necessary.  If a student decides to withdraw, he or she should also verify that the withdrawal is recorded before the Final Withdrawal Date.  The Final Withdrawal Date for this semester is November 18th.  The student is also strongly encouraged to keep any paperwork in case a problem arises.

Students are responsible for understanding the impact that withdrawal from a course may have on their financial aid, veterans’ benefits, and international student status.  Per state law, students enrolling for the first time in Fall 2007 or later at any public Texas college or university may not withdraw (receive a “W”) from more than six courses during their undergraduate college education. Some exemptions for good cause could allow a student to withdraw from a course without having it count toward this limit. Students are strongly encouraged to meet with an advisor when making decisions about course selection, course loads, and course withdrawals.

Missed Exam and Late Work Policies

TARDINESS POLOICY:

Students who are not present when role is taken will be marked tardy.  Excessive tardiness will affect your grade.

MAKE-UP POLICY:

All students that miss assignments must ask the instructor for make-up work. If make-up work is not asked for, it will not be given. All assignments with no grade at the end of the grading period will receive a grade of F for that particular assignment. Make-up work may not be identical to the original assignment.

LATE ASSIGNMENTS:

Assignments that are turned in late may have points deducted from them or may not be accepted at all at the instructor’s discretion.
 

Incompletes

An incomplete (grade of "I") will only be given for extenuating circumstances.  What constitutes “extenuating circumstances” is left to the instructor’s discretion.  If a grade of I is given, the remaining course work must be completed by a date set by the student and professor.  This date may not be later than two weeks prior to the end of the following semester.  A grade of I also requires completion and submission of the Incomplete Grade form, to be signed by the faculty member (and student if possible) and submitted to the department chair.

Students may request an Incomplete from their faculty member if they believe circumstances warrant.  The faculty member will determine whether the Incomplete is appropriate to award or not.  The following processes must be followed when awarding a student an I grade. 

1.      Prior to the end of the semester in which the “I” is to be awarded, the student must meet with the instructor to determine the assignments and exams that must be completed prior to the deadline date.  This meeting can occur virtually or in person.  The instructor should complete the Report of Incomplete Grade form.

2.      The faculty member will complete the form, including all requirements to complete the course and the due date, sign (by typing in name) and then email it to the student.  The student will then complete his/her section, sign (by typing in name), and return the completed form to the faculty member to complete the agreement.  A copy of the fully completed form can then be emailed by the faculty member to the student and the department chair for each grade of Incomplete that the faculty member submits at the end of the semester.   

3.      The student must complete all remaining work by the date specified on the form above.  This date is determined by the instructor in collaboration with the student, but it may not be later than the final withdrawal deadline in the subsequent long semester.  

4.      Students will retain access to the course Blackboard page through the subsequent semester in order to submit work and complete the course. Students will be able to log on to Blackboard and have access to the course section materials, assignments, and grades from the course and semester in which the Incomplete was awarded.  

5.      When the student completes the required work by the Incomplete deadline, the instructor will submit an electronic Grade Change Form to change the student’s performance grade from an “I” to the earned grade of A, B, C, D, or F. 

If an Incomplete is not resolved by the deadline, the grade automatically converts to an “F.”  Approval to carry an Incomplete for longer than the following semester or session deadline is not frequently granted.
