Academic Honesty

"The Department takes the matter of academic honesty very seriously. Academic honesty is essentially giving credit where credit is due. And not misrepresenting what you have done and what work you have produced. When a piece of work is submitted by a student it is expected that all unquoted and uncited ideas and text are original to the student. Uncited and unquoted text, diagrams, etc., which are not original to the student, and which the student presents as their own work is considered academically dishonest."
