Infection Control
“The Dental Assisting Program is committed to utilizing the most current research and technology to maintain an infection control program that is practical while meeting regulatory requirements. The policy for infection control procedures must be followed in strict compliance for the protection of patients, students, faculty, and staff from the transmission of disease or the spread of blood borne pathogens. All dental assisting students, faculty, and staff have the responsibility and ethical duty to comply with the infection control procedures".
Communication
Continuous communication with the instructors is encouraged. To allow for good, open, honest, and transparent communication please follow the guidelines below:
1. Instructor Office Hours are FOR STUDENTS. Please consider this time and opportunity for you to communicate with your instructors.
2. Utilize your AC email for questions regarding grades, absences, policies, etc. This maintains a record of the discussion for both you and the instructor.
3. Check your AC email EVERYDAY. The instructor will use this method of communication to make important announcements and changes in the schedule. This is also how other AC faculty and staff will communicate with you.

Lecture Examinations and Quizzes
Students will be given 5 lecture examinations and several quizzes throughout the course. Exams and Quizzes will be objective in nature (true/false and multiple choice) as well as subjective (short answer, fill in the blank, and essay). The Final Exam will be objective.
Laboratory Assignments
Students will complete several laboratory assignments throughout the course. Specific instructions and grading rubrics will be given for each assignment and located on the grading forms.
Laboratory Competency
Students will be required to complete Competency Examinations in the Lab. These Examinations will assess the student’s ability to competently acquire radiographic images on a manikin prior to exposing live patients. The following grading rubric is used for competency evaluations.
Letter Grade A demonstrates a “Mastery Level” of Competence. Letter grade B demonstrates “Competence” with need for remediation. Letter grade C or below will require remediation and re-testing. A minimum level of Competency must be obtained in order to complete this skills assessment. 93-100=A; 83-92=B; 75-82=C
Grading Criteria
Major Exams 40%
Lab Competency 15%
Quizzes 10%
Assignments 10%
Final 25%
The following grading scale will be used for all Dental Assisting Courses:
A = 93 to 100
B = 83 to 92
C = 75 to 82
F = Below 75
Decimal scores from all graded activities will be rounded as follows:
0.1 - 0.4 — rounded down
0.5 - 0.9 — rounded up
The final course average will be rounded in the same way.
In order to be fair to students who are present and perform the required tasks and because of time restraints, most missed work, especially lab and clinical work can not be made up. Lab and clinical assignments involve the use of a partner. Without you they can not perform their assignments.
Clinical work performed in the radiology area and with Dexter manikins is difficult to make up. We have limited time due to sharing the facility with the dental hygiene students and serving rotations within our own class. In order for you to be successful in this course, it is imperative that you respect your reserved time and keep up with the course work.
Missed written exams maybe made up on the designated "make-up" days. These dates will be given at the start of the class. In order to be fair to the students who take the exam at the scheduled time, Make-up exams will lose 5% of their original value. Please note that make-up exams are most often one to five essay type questions.
Remediation
All students are responsible for his/her own learning. The student is expected to monitor their progress, and should they have any questions or concerns, contact the instructor for assistance.
Review and Remediation will be made available throughout the course and will be documented. The instructor can assist with identifying the need for remediation, but the student should also identify their own needs.
The student is expected to notify the instructor in a timely manner so that remediation can be provided prior to the end of the course.
For didactic remediation, the student will be required to review the content and complete either an assignment or Adaptive Quiz to demonstrate knowledge and comprehension of the content. The instructor reserves the right to allow or deny the student to retest after a failed didactic examination. In the event the student is offered the opportunity to retest, the highest grade possible will be 75.
For Lab and Clinical remediation, the student will be required to meet with an instructor. For failed Competency Evaluations, the student will be required to retest before proceeding to the next lab and clinical assignment. For retesting, the highest grade possible will be 75.
Amarillo College offers several resources for student success. If resources outside of the Dental Assisting program are needed, the student will need to seek assistance through Amarillo College Tutoring Center West Campus.

Regular attendance is necessary for satisfactory achievement of the Dental Assisting Program. Therefore, it is the responsibility of the student to attend class. Due to the amount of information contained in the course work, the student who plans to succeed should attend all lectures, labs, and clinical sessions regularly and promptly. The student will need to come to class on time, fully prepared for that session, with the necessary materials.
There is no distinction between an excused or unexcused absence. In each course, you may have up to TWO absences without it affecting your final grade. On the third absence, the final grade for the course will be reduced by 2 points. On the fourth absence, the final grade for the course will be reduced by 4 points. On the fifth absence, the overall grade will be reduced by 10 points. On the sixth absence, the student will be required to repeat the course. Attendance will be recorded at the beginning of each session. If the student is not present when attendance is taken the student is counted absent. Two bonus points will be added to the final grade for perfect attendance.
All personal appointments should be scheduled during non-instructional hours.
The student should consult a physician regarding illness. If the illness is infectious, the student must take precautions to not spread infection with Amarillo College students and staff. Examples of infectious and communicable diseases includes but is not limited to Upper Respiratory Infection, Gastroenteritis, Influenza, Conjunctivitis, Chicken Pox, Active Tuberculosis, etc.
Students with children should have adequate and dependable arrangements for their care; have an alternate plan to follow when a child becomes ill.
In order to be fair to students who are present and perform the required tasks and because of time restraints, most missed work, especially lab and clinical work cannot be made up. Lab and clinical assignments involve the use of a partner. Without you, they cannot perform their assignments.
Missed exams maybe made up on the designated "make-up" days. In order to be fair to the students who take the exam at the scheduled time, an alternate exam with a loss of 5% of the original value will be given.
