7. EVALUATION PROCEDURES:
30% The student’s grade will be based on the scores received on unit tests.
20% Will be based on the scores received by the student on assignments and worksheets..

30%

Will be based on the scores received by the student on skills performed based on the rating scale value of the Proficiency Task sheets.

 

20%

Will be based on student’s attendance and tardiness (5 pts per session = 75 pts. per semester), clinic team rotation participation (5 pts per session = 75 pts per semester), and professional behavior/ work ethic (See Student Handbook - ex. respectable, team player, responsible patient care, dependable, etc.).  3 tardy’s equate to 1 absence.

PRECLINICAL AND LABORATORY ROTATION

 

Due to the importance of professional behaviors and team participation, all Dental Assisting Students must abide by the clinical rotation schedules posted in the Dental Assisting Clinic. 

The following will apply for each student’s assigned weekly rotation:

·         Each student will work within the assigned team when practicing skills and during student skill test out evaluations.

·         Instructor skill test out evaluations will be completed with the assigned rotation team.

·         If a member of the team is not ready for testing, the remaining partners will assist to bring all members to sufficient competency levels for final evaluation by practicing with the assigned group.

·         Do not sign up for instructor test out prior to completing your student evaluation

·         Task Performance sheets left in the clinic or lab will be taken and not returned to the student.

·         Assigned teams waiting for instructor test out evaluation will be responsible for completing the following list:

o   Instrument processing and stocking operatory supplies

o   Clinic and laboratory housekeeping

o   Working together on classroom assignments, homework, DASO Club projects

·         Five (5) team points will be assigned to each team per week. (Total of 75 points per semester)

·         Each student’s behavior will be respectful and professional* to all team members, faculty and patients.  *See page 4 of the DA Student Handbook for professional behavior.

·         Teams not abiding to the above will have the entire week’s points deducted and/or dismissed from clinical or laboratory session.
