CAES Rules

1. Attendance and Participation

CAES expects students to attend 100% of scheduled classes (including the add/drop period) and complete all assigned out-of-class tasks (if applicable). 20% absence is allowed for emergencies or sick leave. Students who are not able to meet the 80% attendance requirement due to various reasons should contact their teacher immediately. Students may risk failing the course if they miss a substantial proportion of the course without providing any medical certificate or legitimate reason for their absence.

Students have the responsibility to contact their teacher before the commencement of the course if they know in advance they have problems meeting the 80% attendance requirement. Examples of such cases include students who are pending faculty’s approval for their application for leave of absence.

If students know in advance that they have problems with attending the scheduled classes then they should also contact their teacher immediately and provide an explanation. It is very important for the teacher concerned to be informed about this ahead of time so that they can make appropriate arrangements for these students.

CAES classes are highly interactive. We would like our students to get the most out of our courses by actively participating in lessons via responding to their teacher and classmates. If for any reason participation in interactive activities is not possible in some of our courses with a virtual learning element (e.g., internet connection problem)​, students should let their teacher know in advance.

If students have any special needs or circumstances that may affect their attendance or ability to complete course assignments on time, they are strongly encouraged to seek professional advice from HKU-CEDARS ( ​

2. Punctuality

We expect students to be punctual for all the scheduled classes and tutorials of CAES. Students may be marked as partially absent if they are late for 10 minutes or more for a class without a valid reason. Lateness for two times may count as one absence.

The rules stated above apply to both face-to-face and online classes.

3. Academic Honesty

HKU expects all students to display a high level of integrity when completing course assignments. Any form of academic dishonesty will not be tolerated, and failure to observe the rules and conduct of academic integrity will result in negative consequences. As such, you should complete your course assessments honestly at all times. Examples of basic principles of academic honesty include: (i) completing the entire assessments yourself; (ii) NOT submitting the same assessment more than once unless specified otherwise by the course teachers concerned, and (iii) not colluding (i.e. cooperating with others secretly with an intention to deceive) with anyone when producing your work.

We would like to draw your attention to sections 3.1 and 3.2 for details of two common forms of academic misconduct which result in severe consequences.

3.1 Plagiarism and Self-plagiarism 

Plagiarism is defined as “the use of another person’s work (including but not limited to any materials, creations, ideas and data) as if one’s own without due acknowledgement, whether or not such work has been published and regardless of the intent to deceive” in the Policy on Student Plagiarism in Undergraduate and Taught Postgraduate Curricular (116/1080). Some common types of plagiarism include:

1) paraphrasing and/or quoting without acknowledgement;

2) inappropriate paraphrasing and/or quotation of sourced content.

This is not an exhaustive list but it gives you an idea of some common types of plagiarism cases in students’ work.

Self-plagiarism is defined as “the reuse of one’s own work without acknowledging that such work has been submitted elsewhere” in the Policy on Student Plagiarism in Undergraduate and Taught Postgraduate Curricula (116/1080). Students should not submit the same piece of work for different courses (except for adjunct English-in-the-Discipline courses and with teachers’ permission). They should always check with the teacher if they are unsure.

Consequences of Plagiarism

In the University of Hong Kong, plagiarism is a disciplinary offenceIf a submission contains plagiarism, only the unplagiarised parts will be marked. This may result in the work being considered as incomplete, unstructured, lacking content and organization.

The link below contains information about consequences and disciplinary procedures concerning students who have committed plagiarism:

3.2 Ghost Writing and Its Consequences

Ghost writing, also known as ‘contract cheating’, is when a student gets someone (paid or unpaid) to complete part of OR all of an assignment. It is serious academic misconduct. CAES takes ghost writing very seriously and when such cases are confirmed, severe penalty will apply. The assignment concerned will be treated as a non-submission (i.e. 0 mark). Such cases will also be reported to students’ Home Faculty for disciplinary action. If such cases are further reported to the University Disciplinary Committee, the student who is found guilty is subject to various forms of punishment, details of which can be found in section 4 of Statute XXXI of the University’s Statutes and the Disciplinary Committee Regulation:

4. Submission of Assignments

If students are sick and unable to hand in an assignment, they must contact their teacher to let them know immediately. The following are general guidelines on penalties/policies for late submission of assignments for all CAES courses.

  • Assignments which are handed in up to four days late without any medical/legitimate reason will have one full letter grade deducted each day (e.g., a B- becomes a C- after one day late).
  • If the assignment is submitted four days after the deadline without a medical certificate/a legitimate reason, it will be treated as non-submission (N – 0 mark). It is up to the programme coordinator to decide whether such students should be given feedback on this assignment.
  • Students who do not submit an assignment at all or miss an assessment without a medical certificate should be given an N (0 mark).
5. Bad Weather

In the case of bad weather such as Black / Red Rain or Typhoon Signal 8, please follow the university guidelines (updated 2021 by The Registry):

  • (a) Tropical Cyclone Warning Signal No. 8 (or above) is hoisted; or (b) Tropical Cyclone Warning Signal No. 8 will be issued within two hours as announced by the Hong Kong Observatory; or (c) “Extreme conditions” after super typhoons are in force (announced by the Government before the Hong Kong Observatory replaces Tropical Cyclone Warning Signal No. 8 with Tropical Cyclone Warning Signal No. 3); or (d) Black Rainstorm Signal is in force, the following arrangements will apply:
