Academic Integrity
Students should know that the University’s Academic Integrity Policy is available at
https://www.csum.edu/c/document_library/get_file?uuid=ae78af01-0291-4d0f-ad97060861e514d2&groupId=42499 Your own commitment to learning, as evidenced by your
enrollment at Cal Maritime and the University’s integrity policy, require you to be honest in
all your academic course work. Instances of academic dishonesty will not be tolerated.
Cheating on exams or plagiarism (presenting the work of another as your own, or the use of
another person’s ideas without giving proper credit) will result in a failing grade and
sanctions by the University. For this class, all assignments are to be completed by the
individual student unless otherwise specified.
Campus Policy in Compliance with the American Disabilities Act
California Maritime Academy is committed to providing reasonable accommodations to
students with documented disabilities. Students who believe they may need
accommodations are encouraged to contact the Disability Services Office (DSO) in the
Student Engagement & Academic Success Center via email [email protected],
preferably within the first two weeks of class. The DSO is located in Laboratory Building
Room 102. For more information, see our website:
