Academic honesty

The Academic Honesty Policy at UHCL states: Academic honesty is the cornerstone of the academic integrity of the university. It is the foundation upon which the student builds personal integrity and establishes a standard of personal behavior. The complete text of the Policy can be found on pages 76-77 of the 2002-2003 Catalog or on-line.

The Honesty Code of UHCL states: I will be honest in all my academic activities and will not tolerate dishonesty.

Because honesty and integrity are such important factors, you should be aware that failure to perform within the bounds of these ethical standards is sufficient grounds to receive a course grade "F" and be recommended for suspension.

Disability services

Any students with physical disabilities who require special accommodations should inform the instructor and/or the Academic Manager before/on the first class meeting.
