Evaluation Criteria:

Students will demonstrate proficiency on all measurable performance objectives at least to the 75%
level. Mastery of the measurable performance objectives will be assessed through written
competency testing.

Unit Competency Tests
Unit competency tests count for 50% of the final grade. If a student receives a grade of 74% or lower,
he or she must retake the competency test to receive credit for that competency. Only one retake will
be offered. On retaken competency tests, a maximum score of 75% will be given for calculation
purposes.

Quizzes
Quizzes count for 25% of the final grade. Quiz make-ups will require instructor approval based on an
excused absence.

Lab
Lab Objectives count for 25% of the final grade.


Final Grades will be computed using the following grading scale:

A = 92 - 100 ......    Student meets the measurable objectives in an outstanding manner.

B = 83 - 91 .......    Student meets the measurable objectives in an above average manner.

C = 75 - 82 .......    Student meets the measurable objectives.

R = below 75 ......    Student has not met the measurable objectives and must repeat the course.

Students should refer to the Student Handbook for information on Academic Standing Policy,
Academic Honesty Policy, Student Rights and Responsibilities and other policies relevant to their
academic progress.

Attendance: Regular attendance is strongly encouraged.
