Academic Integrity/Conduct Mon 29 August Embry-Riddle is committed to maintaining and upholding intellectual integrity. All students, faculty, and staff have obligations to prevent violations of academic integrity and take corrective action when they occur. The adjudication process will include the sanction imposed on students who commit the following academic violations, which may include a failing grade on the assignment, a failing grade for the course, suspension, or dismissal from the University. 1.Plagiarism: Presenting as one’s own the ideas, words, or products of another. Plagiarism includes use of any source to complete academic assignments without proper acknowledgment of the source. 2.Cheating is a broad term that includes the following:  Giving or receiving help from unauthorized persons or materials during examinations.  The unauthorized communication of examination questions prior to, during, or following administration of the examination.  Collaboration on examinations or assignments expected to be individual work.  Fraud and deceit, which include knowingly furnishing false or misleading information or failing to furnish appropriate information when requested, such as when applying for admission to the University.
