Grading System :


A. Criteria used to evaluate the course objectives will be based on the material presented in the curriculum and on all reading assignments.


B. Final Grade:

1. Lab Criteria Forms 5%

2. Quizzes 10%

3. Three examinations 60%

4. Three Laboratory Competencies 25%



•  Physician's note must be received by the instructor prior to the approval of any make-up examination.


•  Missed quizzes will result in a grade of zero.


•  Grades will be posted by Student Numbers.


•  Students are responsible to schedule missed laboratory sessions within two weeks .


•  Grade Equivalents:


A = 90 - 100 B = 80 - 89 C = 75 - 79 D = 74 - 60

F = below 60

No quality points for plus (+) or minus (-). Only 4 - A; 3 - B; 2 - C; 1 - D; 0 - F




Types of Tests :


Three examinations will be given throughout the semester.


Announced Quizzes will be given during scheduled lecture every two weeks.


Practical Examinations: Students must perform at a level of 80% or greater on competency examination prior to performance of any function on clinic clients.


Students performing below the 80% level on competency exams , must remediate and retake the competency. ALL competency examinations must be taken and competency attained. Students will retain their original grade .

Students who have established clinical competency may begin procedures on clinic clients after the Competency Examinations.


* Clinical competency is determined when the prescribed functions listed under #1 in course objectives, are performed on clinic clients at a minimum level of 80%.


The following must be met for advanced functions to be counted as a requirement:


Acceptable: No critical areas missed and a total score of 80% or higher.


Unacceptable: One (1) or more critical areas missed and/or total score of less than 80%.


It must be stated that the other functions listed in #3 of the course objectives are taught to conceptual proficiency. Students would need additional training in these skills to attain clinical competency.


Remediation :


In the event that the student's grade is below 75%, the student will be required to re-test that unit until the student achieves a minimum score of 75%. The student will retain their original grade. This must be done before the next Unit Exam. Students are encouraged to see the Course Director for remediation.


Attendance Policy : Following three absences from the lecture and/or laboratory section, the final grade will be lowered by one (1) letter.


A student who is late three times to the lecture and/or laboratory section will have an absence added.


All laboratory sessions must be made up within two weeks.


Method of Presentation :


•  Lectures and Discussion

•  PowerPoint Presentations/Videos

•  Instructional Models

•  Demonstration

•  Realia

•  Laboratory Exercises/Student/Peer Evaluations

•  Quizzes, Three Examinations, and Three Competency Examinations

•  Web-Enhanced

The course topic outline states what will be covered through in-depth lectures. However, additional material will be added in lectures to cover the “latest” information on research and development of dental materials and current controversies of materials and/or techniques. Some themes and premises may be restated during the lectures but in forms different enough so I hope they will resonate...not repeat!


Bear in mind, the material in this course is ever growing and so will our coverage and discussions.
