Methods of Evaluation of Competencies:

Evaluation of student mastery of course competencies will be accomplished using the following methods:

Written examinations	70-90% of total grade
Assignments		10-30% of total grade
Lab Competencies 	Satisfactory on Satisfactory/Needing Improvement
evaluation by the instructor

Grading Scale:
A  =   92-100%  	
B  =   83-91%  	
C  =   75-82%*	
D  =   67-74%	
F  =    0 - 66%

*minimum required to continue in program

Caveats:

  1. Students are expected to comply with the JCCC Student Code of Conduct as detailed in the JCCC College Catalog. Failure to comply may result in a faculty decision regarding program promotion and constitute a reason to fail the course.
  2. A grade of “C” or better is required for the course for program promotion to subsequent polysomnography course work.
  3. Students will need basic word processing and Internet skills for the completion of some papers, exercises and projects.

Disabilities:

If you are a student with a disability, and if you will be requesting accommodations, it is your responsibility to contact Access Services. Access Services will recommend any appropriate accommodations to your professor and his/her director. The professor and director will identify for you which accommodations will be arranged.

JCCC provides a range of services to allow persons with disabilities to participate in educational programs and activities.
