VI.      STUDENT REQUIREMENTS AND METHODS OF EVALUATION:

Lecture:          Reading assigned materials, note taking and participation in classroom discussion is expected.

                                    Written examinations are used to evaluate student progress following each unit.  A comprehensive final exam will be given at the end of the semester.  All of the grades from these exams will be averaged equally to determine the student’s final lecture grade.

            Laboratory:    Students are required to complete all assigned projects.

                                    Students are responsible for the cleanliness of the laboratory and must follow the posted laboratory rules.

Final Grade:   A grade of “C” is required in the lecture portion and in the laboratory portion of this course for graduation from the Dental Assisting Program.

                                    The student’s final grade will be calculated: 50% lecture grade 

                                                                                                               50% laboratory grade

The following grading scale will be used as a guide in determining the grade for this course:

                                    A=       90 - 100%

                                    B=       80 - 89%

                                    C=       70 - 79%

                                    D=       60 - 69%

                                    F=       0 - 59%
