Common Course Objectives: To prepare students for entry-level employment and certification through ASE.
GRADING:
- Exams will make up 35% of total grade.
- Daily grade will make up 35% of total grade
- Homework assignments and quizzes will be 40% of daily grade. Participation in lab activities will constitute 40% of your daily. Bringing tools, supplies and proper attire (as stated bellow) will be 20% of your daily grade.
- Notebook will make up 10% of total grade. It needs to have your copy of the syllabus, printout of your SP2 certificates and any handout assignments.
- Attendance will constitute 20% of total grade. Each day missed and not made up will bring your total grade down 10 points. More than 4 missed days will prevent you from passing.
- A total passing grade of "C" will not be awarded to any student who does not achieve an average letter grade of "C" or higher on exams. You must average a “C” or higher on your exams to pass the class.
- A positive, constructive attitude also plays an important part the overall evaluation of the shop work and will be directly related to the shop grade. *(1C-1,2,4,5, 2A-4)
- Any withdrawals are the responsibility of the student. If student fails to make the withdrawal by the drop date, an automatic grade of "F" will be awarded. *(1C-1,4, 2A-4)
COURSE POLICIES:
1. Regular attendance is required. Only limited absences and tardiness 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 day of class after 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-2,4,5)
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 this three weeks before the start of the semester.
8. Proper shop attire will be worn at all times. This includes, but is not limited to, work pants, a work shirt with a collar, work boots or shoes, and safety glasses, all similar to what would be worn at a professional automotive repair shop. Flip flops, sandals, loose baggy clothing, dangling jewelry, or clothing that is too revealing in nature are not allowed. The student may be sent home at the instructor’s discretion. Violations will lower the student’s grade and possibly cause the student to fail the course.
HEALTH & SAFETY PROTOCOLS
ACC ID badges or Student ID cards will be required for all employees and students upon entry. Employees and students must display their I.D. at all times. Hays CISD badges are allowed for entry at Lehman High School only.
RELIGIOUS HOLIDAYS:
If you observe a religious holiday and miss class, you must notify your instructor in writing two weeks in advance to arrange to take a test or make up an assignment. A religious holiday is a holy day observed by a religion whose place of worship is exempt from property taxation under Section 11.20, Tax Code.
ADMINISTRATIVE WITHDRAWAL:
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 (96 hours of instruction), you can be dropped after 12 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!
TARDINESS POLICY:
Students who are not present when roll is taken will be marked tardy and may be marked absent if you do not let the instructor know you are present. Excessive tardiness will affect your grade. Students more than 20 minutes late may be counted absent.
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 zero for that particular assignment. Make-up work may not be identical to the original assignment and may not always be available.
LATE ASSIGNMENTS:
Assignments that are turned in late may, at the instructor’s discretion, have points deducted from them or may not be accepted at all.
ACADEMIC DISHONESTY:
Scholastic dishonesty includes, but is not limited to, cheating on a test, plagiarism, and collusion.
Cheating on a test includes:
1. Copying from another student’s test paper; using, during a test,
materials not authorized by the person giving the test.
2. Collaborating with another student during a test without permission.
3. Knowingly using, buying, selling, stealing, transporting, or soliciting in
whole or part the contents of an un-administered test.
4. Bribing another person to obtain a test that is to be administered.
Plagiarism means the appropriation of another’s work and the unacknowledged incorporation of that work in one’s own work for credit.
Collusion means the unauthorized collaboration with another person in preparing written work, particular test, or assignment involved. In extreme cases or for repeated violations, guilty students can be assigned a failing grade in a course or recommended for probation or dismissal from the College System.
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. Vehicles older than 10 years may be excluded.
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. Leaving your work area dirty will adversely affect your grade.
NATEF:
The Board of the National Institute for Automotive Service Excellence (ASE) 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 (NATEF). 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.
Statement on Students with Disabilities
Each ACC campus offers support services for students with documented disabilities. Students with disabilities who need classroom, academic or other accommodations must request them through the office Student Accessibility Services (SAS). Students are encouraged to request accommodations when they register for courses or at least three weeks before the start of the semester, otherwise the provision of accommodations may be delayed. Students who have received approval for accommodations from SAS for this course must provide the instructor with the ‘Notice of Approved Accommodations’ from SAS before accommodations will be provided. Arrangements for academic accommodations can only be made after the instructor receives the ‘Notice of Approved Accommodations’ from the student. Students with approved accommodations are encouraged to submit the ‘Notice of Approved Accommodations’ to the instructor at the beginning of the semester because a reasonable amount of time may be needed to prepare and arrange for the accommodations. Additional information about Student Accessibility Services is available at http://www.austincc.edu/sas
USE OF ACC EMAIL
All College e-mail communication to students will be sent solely to the student’s ACCmail account, with the expectation that such communications will be read in a timely fashion. ACC will send important information and will notify you of any college related emergencies using this account. Students should only expect to receive email communication from their instructor using this account. Likewise, students should use their ACCmail account when communicating with instructors and staff. Information about ACCmail, including instructions on setting up an account, can be found at http://www.austincc.edu/accmail/
Student and Instructional Services
ACC strives to provide exemplary support to its students and offers a broad variety of opportunities and services. Information on these services and support systems is available at: http://www.austincc.edu/support/

For help setting up your ACCeID, ACC Gmail, or ACC Blackboard, see a Learning Lab Technician at any ACC Learning Lab.
ATTENDANCE POLICY:
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 absences within reason, with just cause, and at my discretion. This applies only to the number of absences counted towards dropping a student, not daily/shop grades. You WILL NOT pass the class if you have more than 2 absences (this includes any accumulation of missed time up to 2 days or 10 hours of absence). Tardiness, leaving early, or disappearing for any length of time, is considered time absent from class and will affect your grade.
EXCESSIVE ABSENCES/ WITHDRAWAL:
Although it is the responsibility of the student to drop a course for nonattendance, the instructor has full authority to drop a student for excessive absences, excessive/habitual tardiness, lack of progress, missed assignments, not meeting course prerequisites, failure to attend the first class meeting, safety violations, etc. Students who continue attending class after the official withdrawal date has passed are not eligible to be withdrawn by the instructor. These students must be assigned a grade on the final grade sheet. Student’s that are not on the official roster cannot attend class or be in the shop for safety/liability reasons.
Cell Phones
Cell phones are not allowed to be used during class. Students needing to make calls or send text may do so by stepping out of class. If a student continually disrupts, class disruption policy will be enforced. You may be withdrawn from class for violating this policy.
CAMPUS CARRY: ACC LOCATIONS ONLY
Statement for classroom courses with physical activity (non-exclusion zone)
The Austin Community College District concealed handgun policy ensures compliance with Section 411.2031 of the Texas Government Code (also known as the Campus Carry Law), while maintaining ACC’s commitment to provide a safe environment for its students, faculty, staff, and visitors.
Beginning August 1, 2017, individuals who are licensed to carry (LTC) may do so on campus premises except in locations and at activities prohibited by state or federal law, or the college’s concealed handgun policy.
It is the responsibility of license holders to conceal their handguns at all times. Persons who see a handgun on campus are asked to contact the ACC Police Department by dialing 222 from a campus phone or 512-223-7999.
IMPORTANT: Automotive classes may involve considerable physical activity. Bending, stretching, lifting, and other rigorous activities associated with (class name) occur regularly in class. Such activities may expose concealed weapons and place the license holder in violation of state law. Therefore, it is recommended that concealed weapons be stored in a secure place as defined by college policy prior to entering the classroom, studio, or learning space.
Refer to the concealed handgun policy online at www.austincc.edu/campuscarry.
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 and the tool room. 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. Vehicles more than 10 years old may be excluded from shop work. Vehicles that must be left overnight must be cleared with your instructor and the tool room and you must leave the keys.
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 and work areas will be cleaned and tools put in the proper place before class will be dismissed. Failure to cleanup at the end of each class will lower your final grade 5 points per occurrence.
