This is posted on Compass and found in the VCE student handbook. Students are NOT permitted to bring mobile phones and/or any other electronic communication devices (including IPods and MP3 Players) into the examination room. SCHOOL ASSESSED COURSEWORK/EXAM CODE OF CONDUCT Students are required to observe the following rules for all VCE assessments as well as the college’s day-to-day rules. VCAA rules shall apply with appropriate and reasonable modifications to students who have disabilities or other impairments. All supervisors are issued with directions or the administration of the VCE assessments and are required to report all alleged breaches of these rules. Supervisors have the right to check any authorised materials that are taken in the assessment. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. Students must not cheat or assist other students to cheat. Students must not take any action that gives or attempts to give them or another student an unfair advantage in a VCE assessment. Students must not allow, induce or assist any other person to present for a VCE assessment in their place. Students must not present for a VCE assessment in another student’s place. Students must not present for a VCE assessment under the influence of alcohol or drugs. Students must obey and observe all proper instructions or directions given by their supervisor. Students attending a VCE assessment may bring only materials and equipment approved for that assessment task. It is the student’s responsibility to have all the necessary materials to complete the assessment task. There is to be no sharing of materials. Students must not possess mobile phones and electronic devices that are capable of storing, receiving or transmitting information or electronic signals, such as recorded music and video players, organisers, dictionaries and computerised watches, during a VCE assessment. Students detected with any device defined in Rule 8 must, upon the direction of a supervisor, surrender that device for inspection. An investigation by the VCE panel will occur, with the likelihood that no grade will be awarded for the assessment task. Students must not bring into or possess in the examination room any drinks or food except under special circumstances as approved and directed by the VCAA. Bottled water is permitted in the examination room under approved conditions. Students must not communicate with any other student while the VCE assessment is being conducted. Students must not cause any nuisance, annoyance or interference to any other student during a VCE assessment. Students must not remove or tear out any part of a bound reference, question/task book, question and answer book or answer book, except where permitted, for example formula sheets. Students must not remove any response material, used or unused, from the examination room. Students must not begin to write or mark their paper or response material in any way, or use a calculator, until advised by a supervisor that writing may commence. Students must raise their hand if they wish to communicate with a supervisor. Students must not leave their place until permitted by a supervisor. Students will not be permitted to leave the VCE assessment until the completion of the task. Students must cease writing when instructed to do so by a supervisor. Students must remain silent and seated in their place at the end of the VCE assessment until response materials have been collected and checked, and an announcement is made permitting students to leave the examination room. Students must not communicate with an assessor, before, during or after a VCE assessment, except when communication is necessary for the conduct of the assessment. CALCULATORS Scientific Calculators – Are permitted for use in Accounting, Algorithmics, Chemistry, Computing: Software Development, Environmental Science, Further Mathematics, Mathematical Methods, Physics, Specialist Mathematics, and Systems Engineering. CAS Calculators – VCAA-approved CAS calculators are permitted for use in Further Mathematics, Mathematical Methods and Specialist Mathematics. The use of CAS software may only occur if prior approval has been granted in writing by the VCAA to the principal of the school. DICTIONARIES GAT, English and English an Additional Language (EAL) – English and/or bilingual printed dictionary may be used. Language Written Examinations – Any printed monolingual and/or bilingual dictionary in one or two separate volumes. Dictionaries may consulted during both reading and writing time. Dictionaries are NOT permitted in any other VCE assessments including Language oral examinations. Dictionaries that contain a thesaurus are NOT permitted. Dictionaries must NOT contain any highlighting or annotation. Electronic dictionaries are NOT permitted.
