7.	EVALUATION PROCEDURES:
	60%	The students grade will be based on the scores received on unit test.
	10%	Will be based on the score received by the student on the final examination.
	10%	Will be based on the scores received by the student on skills performed based ont he rating scale value of the Proficiency Task sheets.
	20%	The students grade will be based on the instructors evaluation of the students attendance pattern, demonstration of a professional attitude, and participation in class/laboratory and activities/discussions.
	Note:
	If no final examination is given 70% of the students grade will be based on the scores received on unit test, 10% on task proficiencies and the 20% criteria remains.
	At the completion of the course the student should be able to do all the basic dental assistant functions required for successful completion of the program. These competencies will be evidenced by the successful completion of 75% of the tasks in each unit.

Raw Score Range				Grading Scale Letter Grade	Grade Point Earned (Credit Only)
	100	to	93	A	12
	92	to	85	B	9
	84	to	75	C	6
	74	to	69	D	3
	68	to	0	F	0

	Special Remarks:
	A.	If a student is absent on a schedule examination day the student must call with reason for absence prior to examination and make arrangements with the instructor to make up the exam within one week. Failure to take a scheduled examination at the appointed time without prior arrangement with the instructor will result in a 2-5 point reduction in the score of any make-up examination. Students of the Dental Assisting Program are allowed to make up three (3) tests per semester to the above guidelines, any test made up after three receives an automatic 10 point deduction.
	B.	Pueblo Community College Dental Assisting Program will adhere to the Academic Dishonesty Policy, which is stated in your DA Student Handbook, for any and all acts of cheating, fabrication, facilitating academic dishonesty and plagiarism.
