Student Conduct and Responsibilities:
A high standard of conduct is expected of all Amarillo College students. The Student Code of Conduct is defined in the Amarillo college Student Rights and Responsibilities publication. The document may be located at www.actx.edu under the student tab.
“Amarillo College expects a high standard of conduct from its students. Students are expected to comply with the law, respect proper constitutional authority, and obey College policies, rules and regulations. Unacceptable conduct is defined as an action or behavior that is contrary to the best interest of a fellow student or students, the faculty or staff, the College, or the teaching/learning process. Students failing to perform according to established standards may be subject to disciplinary action. Policies, standards, rules and regulations apply to students attending College activities whether the activity takes place on or off campus.
Each student shall be responsible for becoming knowledgeable of the contents and provisions of College policies, rules, and regulations concerning student conduct. In some cases, individual programs may have approved policies for student conduct which also apply to student conduct in those programs. Integrity and common sense will guide the actions of each member of the college community both in and out of the classroom. Any student who fails to perform according to expected standards may be disciplined.”
The Amarillo College Dental Hygiene Program has specific policies which apply to student conduct within the program. These policies may be implied or written. The course syllabus and the program manual are sources for specific student conduct policies for dental hygiene students at Amarillo College.
Professional Standards
1. Student is prompt for class.
2. Student is prepared for class sessions.
3. Student assumes responsibility for his/her own learning.
4. Student is concerned with excellence in learning rather than just meeting minimal criteria.
5. Student applies lecture material in the clinic setting.
6. Student will seek faculty assistance if needed, and will monitor their own progress in meeting course requirements.
7. Student maintains his/her composure, dealing with conflict in a constructive way.
8. Student exhibits an attitude of respect for classmates, faculty and staff.
9. Students may not be disruptive or talk to each other during lectures, presentations, guest lectures, etc. Should this occur, the student will be asked to leave the classroom immediately.
Electronic and Recording Devices:
In order to maximize learning, personal use of cell phones is prohibited in this course. Students my check cell phones at designated breaks given by the instructor. Those students who have children or who anticipate an emergency situation should give caretakers and family members the Office Supervisor’s phone number (806-354-6050) and have calls directed to her first. She will then act accordingly to inform the student.
Academic Grievances:
A student, who has a grievance concerning a course in which he or she is enrolled or a grade, should make an appeal in the following order to the: (1) Instructor (2) Department Chair/Program Director (3) Dean of Health Sciences (4) Vice President of Academic Affairs (5) College President in that order.
The following criteria will be used to determine your grade
Lecture and Chapter Quizes given each week 50%
Lab participation, projects and competency sheets 30%
Comprehensive Final (including case studies) 20%
The following grade scale applies throughout this course:
A = 93 to 100%
B = 83 to 92%
C = 75 to 82%
F = Below 75% (Note: A grade of "D" is not possible in this course.)
Mandatory Skills Building/Tutoring:
In an effort to increase student success in DHYG courses, and to assist students having difficulty understanding complex subject areas, any student who scores below a 75% on any exam (excluding the Final Exam) must complete a mandatory skills building assignment before taking the next exam. Before receiving a skills assignment, students must first schedule a time with the instructor. The assignment will be given at that time.
Attendance:
“Regular attendance is necessary for satisfactory achievement. Therefore, it is the responsibility of the student to attend class in accordance with the requirements of the course as established by the instructor” (Amarillo College Student’s Rights and Responsibilities Publication, http://catalog.actx.edu/content.php?catoid=18&navoid=813#Academic_Information). Due to the tremendous amount of information contained in this course, the student who plans to succeed should also plan to attend all course sessions regularly and promptly. Without question, the instructor expects each student to be present at each session. Unfortunately, no one has ever developed a short cut to replace hours of actual experience needed to master a new skill. Therefore, the student must be present to acquire the specific knowledge in this subject.
Absences will be monitored and evaluated to determine the student’s final course grade. The student may have no more than 1 absence in this course without affecting the final grade. Beginning with the 2nd absence, 2 points will be deducted from the final grade; on the 3rd absence, 3 points will be deducted; on the 4th absence, 4 points will be deducted. On the occurrence of the 5th absence, the student will fail the course and be required to repeat the course. Attendance will be taken at the beginning of each lecture and lab session. Students who are not present when attendance is taken will be counted as absent. The student is expected to be present in class at the time the class or lab is scheduled to begin.
STUDENTS WHO ARE LATE TO CLASS OR LAB, OR WHO LEAVE CLASS OR LAB EARLY, WILL BE COUNTED AS ABSENT. (“Late” is defined as the student not being in his/her seat and ready for the class to start at the scheduled class time.)
The student will receive 2 bonus points to the final grade of this course if the student has perfect attendance for the semester.
Make-up Policy:
If a student is absent on the day when an examination is given, the student may make-up the missed work as follows:

2. The missed work must be made up within TWO Amarillo College school days where the day ends at 4:00 pm.
