COLLEGE POLICIES

Statement on Academic Integrity

Austin Community College values academic integrity in the educational process.  Acts of academic dishonesty/misconduct undermine the learning process, present a disadvantage to students who earn credit honestly, and subvert the academic mission of the institution. The potential consequences of fraudulent credentials raise additional concerns for individuals and communities beyond campus who rely on institutions of higher learning to certify students' academic achievements, and expect to benefit from the claimed knowledge and skills of their graduates. Students must follow all instructions given by faculty or designated college representatives when taking examinations, placement assessments, tests, quizzes, and evaluations.  Actions constituting scholastic dishonesty include, but are not limited to, plagiarism, cheating, fabrication, collusion, falsifying documents, or the inappropriate use of the college’s information technology resources.  Further information is available at https://www.austincc.edu/about-acc/academic-integrity-and-disciplinary-process

 

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 four classes 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, 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.

9. No video or audio recordings of any part of class is permitted without prior written permission from the instructor.

10. Campus Carry

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.  In addition, concealed weapons are not allowed on ACC-sponsored field trips where the school owns or has chartered or leased vehicles for transportation. 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.   Please refer to the concealed handgun policy online at http://austincc.edu/campuscarry



 

IMPORTANT: Automotive classes may involve considerable physical activity. Bending, stretching, lifting, and other rigorous activities associated with automotive repair 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. 

ATTENDANCE POLICY:

Attendance on the first day of class is MANDATORY! Students who miss the first day of class may be dropped from the course. 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. You WILL NOT pass the class when you have more than 3 absences. In the event the college or campus closes due to unforeseen circumstances (for example, severe weather, pandemic or other emergency), the student is responsible for communicating with their professor during the closure and completing any assignments or other activities designated by their professor as a result of class sessions being missed. Regular and punctual class and laboratory attendance is expected of all students.  If attendance or compliance with other course policies is unsatisfactory, the instructor may withdraw students from the class. For online class: Regular and timely class participation in discussions and completion of work is expected of all students.  If attendance or compliance with other course policies is unsatisfactory, the instructor may withdraw students from the class.

 

 

 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. 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. The College defines withdrawals as occurring after the official reporting date of the semester, typically the 12th class day.  In addition, the Legislature has mandated the Rule of Six (see below).  There may also be financial aid issues. 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 on the first page of this syllabus.  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.


 

INCOMPLETE

A grade of incomplete may be given for a student with excessive absences only under the most extreme circumstances. It will require documented excused absences from a doctor, hospital, police report, lawyer, etc…..

 

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.”



 

DETAILED GRADING FORMULA:

 

Attendance: 10%

This grade is based upon your attendance and punctuality only. Being late and leaving early are reflected in this grade. You can miss no more than 3 classes and still achieve a passing grade. Once you’ve missed 4 classes, you must drop or receive an F!!!

 

ELECTUDE Homework: 35%

This grade is based upon Electude homework assigned and completed during the semester. Electude assignments will come from their website https://txaustincc.electude.com/ 

By the end of the semester, the homework must be completed for every Electude assignment, and it’s due one week from when it is assigned. Late assignments may have points deducted at my discretion or not be accepted at all.

 

Job Sheets, Repair orders: 10%

Job Sheets are assigned with each topic covered and are completed in the shop. For shop work that is not part of an assignment, a job order or repair order will be filled out at the end of class so I can keep track of the shop work you’ve completed during the semester. This grade is based upon job sheets and shop work completed for the semester. 

 

Quizzes: 5%

Occasionally, or often, a quiz will be given at the beginning of class. This grade is based upon the average of all quizzes during the semester. You cannot make up a missed quiz.

 

Tests, ACDelco Classes: 10%

Tests will be given during the semester covering a portion of the course material. The average of all tests will be worth 10% of your final grade. Tests may be on paper, online, on the computer, hands-on, or a combination of these. ACDelco online training may also count as test grades.


 

Daily Grade: 10%

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. It will also be based upon your shop attire, attitude, and ability to show proficiency for each assigned ASE/NATEF task. 

 

Notebook: 5%

A notebook will be turned in at the end of the semester. See the last page of the syllabus. Your notebook will be graded on completeness including syllabus, tests, quizzes, homework for each chapter, handouts, worksheets, job sheets and notes.  The notebook will count 5% of your final grade. 

 

Research Paper / PPT Presentation:   5%

This grade is based on completion of the semester’s research paper or power point presentation according to the criteria listed at the end of this syllabus. It will count for 5% of your final grade.

 

Comprehensive Final Exam: 10%

15% of your course grade is the final exam. This 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. This exam is a stand-alone 10% and is not counted in the 10% Test/Delco average. 

 

THE GRADING SCALE:

 

        90-100 A

80-89   B

    70-79   C

60-69   D

  1. F

 

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 WITHDRAWALS:

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 30 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.

 

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.

 

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, or required by the instructor, every day to class. Borrowing of tools is discouraged. 

 

TESTING CENTER POLICY

Tests may or may not be given in the testing center. 

 

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 unadministered 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.

STUDENT RIGHTS & RESPONSIBILITIES:

 

Academic freedom is a foundation and hallmark of higher education.  In the context of college-level courses, it specifically refers to the rights of free expression and respect for others with differing opinions.  Students at the college have the rights accorded by the U.S. Constitution to freedom of speech, peaceful assembly, petition, and association. This concept is accompanied by an equally demanding concept of responsibility on the part of the student.  Just as you are expected to exercise these rights with respect for state and federal law in the larger world, you are expected to exercise these rights as a student with respect for the college’s standards of conduct.  These rights carry with them the responsibility to accord the same rights to others in the college community and not to interfere with or disrupt the educational process.  Students and faculty alike should enable a climate of mutual respect and civility while fostering the freedom to debate and discuss the merits of competing ideas. Enrollment in the college indicates acceptance of the rules set forth in the student standards of conduct policy, which is administered through the office of the campus dean of student services. Due process, through an investigation and appeal process, is assured to any student involved in disciplinary action.

 

Student Complaints

A defined process applies to complaints about an instructor or other college employee. You are encouraged to discuss concerns and complaints with college personnel and should expect a timely and appropriate response. When possible, students should first address their concerns through informal conferences with those immediately involved; formal due process is available when informal resolution cannot be achieved.

Student complaints may include (but are not limited to) issues regarding classroom instruction, college services and offices on the basis of actual or perceived race, color, national origin, religion, age, gender, gender identity, sexual orientation, political affiliation, or disability. Further information about the complaints process, including the form used to submit complaints, is available at: http://www.austincc.edu/students/students-rights-and-responsibilities/student-complaint-procedures

 

Statement on Privacy

The Family Educational Rights and Privacy Act (FERPA) protects confidentiality of students’ educational records. Grades cannot be provided by faculty over the phone, by e-mail, or to a fellow student. Class grades are updated periodically in Blackboard.

Safety Statement

Health and safety are of paramount importance in classrooms, laboratories, and field activities. Students are expected to learn and comply with ACC environmental, health and safety procedures and agree to follow ACC safety policies.  Emergency Procedures posters and Campus Safety Plans are posted in each classroom and should be reviewed at the beginning of each semester.  All incidents (injuries/illness/fire/property damage/near miss) should be immediately reported to the course instructor. Additional information about safety procedures and how to sign up to be notified in case of an emergency can be found at http://www.austincc.edu/emergency  Everyone is expected to conduct themselves professionally with respect and courtesy to all. Anyone who thoughtlessly or intentionally jeopardizes the health or safety of another individual may be immediately dismissed from the day’s activity and will be referred to the Dean of Student Services for disciplinary action. In the event of disruption of normal classroom activities due to an emergency situation or an illness outbreak, the format for this course may be modified to enable completion of the course. In that event, students will be provided an addendum to the class syllabus that will supersede the original version.

Discrimination Prohibited

The College seeks to maintain an educational environment free from any form of discrimination or harassment including but not limited to discrimination or harassment on the basis of race, color, national origin, religion, age, sex, gender, sexual orientation, gender identity, or disability. Faculty at the College are required to report concerns regarding sexual misconduct (including all forms of sexual harassment and sex and gender-based discrimination) to the Manager of Title IX/Title VI/ADA Compliance.  Licensed clinical counselors are available across the District and serve as confidential resources for students. Additional information about Title VI, Title IX, and ADA compliance can be found in the ACC Compliance Resource Guide available at: https://drive.google.com/file/d/1o55xINAWNvTYgI-fs-JbDyuaMFDNvAjz/view

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 students 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 ACC email accounts, including instructions for accessing it, are available at:  http://www.austincc.edu/help/accmail/questions-and-answers

 


 

Use of the Testing Center

Under certain circumstances, examinations may have to be taken in a testing center. The ACC Testing Centers follow standard procedures so students know what to expect when they arrive to take their tests. Students should familiarize themselves with the student guidelines. Students must present an ACC student ID card or government issued ID and know their ACC ID number before they can test.

 

It is necessary to check in at the Testing Center kiosk before taking a test. To check in, one must know the following information:

  • Student ID number
  • Course prefix and number
  • Course synonym
  • Course section number
  • Test number
  • Instructor’s name

 

Personal belongings such as backpacks, books, and electronic devices (including, but not limited to, cell phones and smart watches) are not allowed in the Testing Center. Possession of prohibited items or accessing unapproved resources in the testing room will result in the immediate termination of the exam and possible disciplinary action.

 For additional information on using the Testing Center, please go to: http://www.austincc.edu/students/testing-services/instructional-testing

STUDENT SUPPORT SERVICES

The success of our students is paramount, and ACC offers a variety of support services to help, as well as providing numerous opportunities for community engagement and personal growth.

 

Student Support

ACC strives to provide exemplary support to its students and offers a broad variety of opportunities and services.  Information on these campus services and resources is available at  http://www.austincc.edu/students.

Student Accessibility Services

Students with documented disabilities who need classroom, academic, or other accommodations must request them through the office Student Accessibility Services (SAS).   SAS offices are located at each major campus.  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 document titled “Notice of Approved Accommodations” from SAS before accommodations will be provided. Accommodations will not be provided retroactively.  Arrangements by the instructor for academic accommodations can only be made after he or she receives the “Notice of Approved Accommodations” from the student. Additional information about Student Accessibility Services is available at https://www.austincc.edu/offices/student-accessibility-services-and-assistive-technology

Academic Support

ACC offers academic support services on all of its campuses. These services, which include face-to-face and online tutoring, academic coaching, and supplemental instruction, are free to enrolled ACC students. Tutors are available in a variety of subjects ranging from accounting to pharmacology. Students may receive these services on both a drop-in and referral basis. Tutoring schedules can be found at:  https://www.austincc.edu/students/tutoring/tutoring-schedules

Pass/No-Pass

ACC has temporarily implemented a Pass/No Pass option for grading.  Students are permitted (but not required) to convert any course sections to Pass/No-Pass grading. The following procedures will apply.  After receiving their grade for the semester, students will have until {insert date] to elect Pass/No-Pass grading.  Only grades of C or better in a course may be converted to P (Pass). Grades of D and F may be converted to NP (No-Pass).  All courses for which students receive passing (P) grades will count toward ACC degree requirements, which may override some departmental or college policies.  A grade of Pass/No-pass will not count toward a student's grade point average (GPA); however a grade of Pass will count toward earned semester hours. Students should consider the possible implications of electing the Pass/No-Pass option (e.g., on course transfer, GPA calculations, financial aid, etc.).  Academic transcripts will have a note added indicating the Pass/No Pass grading option is due to the Corona-virus pandemic. This is subject to change for any semester.

 Library Services

ACC has a full-service library at each of its campuses to support ACC courses and programs and to provide students with research and assignment assistance from expert faculty librarians, computers, course reserves, laptop and tablet check out, study spaces, and copying, printing, and scanning services.  In addition, ACC students have full rights and privileges to access Library Services online 24/7 via the ACC Library website and students can use their ACCeID logins to access all online materials, including ebooks, articles from library databases, and streaming videos.   ACC Libraries also provide an “Ask a Librarian” service, which allows  students to reach a librarian 24/7 through online chat.  Faculty librarians are also available via email, phone, and in person seven days a week during hours of operation. Visit:

 

 

In partnership with ACC’s Student Support Center, ACC Libraries also maintain a limited collection of textbooks for students to borrow. Priority access to the textbook collection is given to students receiving assistance. More information is available on the ACC website by searching “Student Support Center Textbook Collection.”

 

Student Organizations

ACC has over seventy student organizations, offering a variety of cultural, academic, vocational, and social opportunities.  They provide a chance to meet with other students who have the same interests, engage in service-learning, participate in intramural sports, gain valuable field experience related to career goals, and much else.  Student Life coordinates many of these activities, and additional information is available at http://sites.austincc.edu/sl/.
