Modes of Evaluation

  • Assignments must be submited at the beginning of the class on the are due dat.
  • A late penalty of 10% per day is assessed for late assignments, including those not handed in at the beginning of class when due.
  • Material will not be accepted after one week following the due date and/or when the marked material is returned to students, whichever comes first.
  • Assignments are to be prepared by computer.

Absenteeism and Exams
  • Students should be aware that absenteeism almost guarantees an inability to achieve satisfactory grades.
  • Students who are absent for a final examination due to an emergency (e.g., motor vehicle accident, hospitalization or death in the family) may provide official documentation within five days of the missed exam and be provided a deferred exam at a later date.  Official documentation includes a death notice or an original doctor’s certificate identifying the date, length of time expected absence and the specific reason for the absence.  Examinations missed without official documentation and approval result in a grade of zero.
  • There are no deferred options for missed testso or midterms.  The value of missed tests, at the discretion of the Faculty, will be added to other evaluation components

English Proficiency
  • All written work should demonstrate the following characteristics for clarity and conciseness:
-writing is consistent with the rules of English grammar
-spelling and punctuation are correct
-sentences are structured correctly
-main ideas are supported with specific, relevant examples and reasons
-work flows logically through supporting statements/paragraphs
-work is arranged in correct format (e.g., as a report, essay)
-up to 10% of the final grade may be deducted on all work if the above English competencies are not met.

Format for Assignments
  • Students must use the standard, APA style for quoting sources.   Help is available at:

    Grading is based on the following marking scheme: 

    Assignments 25%
    Mid-Term 35%
    Final Exam 40%


    Since this is a professional credit subject, marking standards reinforce professional practice by demanding legible, tidy work. Written assignments should be well organized and grammatically correct, with proper spelling and punctuation. Late assignments are penalized. For particulars, please obtain standards, dates, etc. from your instructor. 

    While attendance and participation in class discussions are not formally part of this evaluation schedule, you should be aware that absenteeism will almost guarantee your inability to achieve satisfactory grades. Some of the progress tests and quizzes may not be announced in advance and details of assignment requirements may be explained in class. There is no formal provision for make-up tests to replace tests you miss.
