Credit Transfer and/or Recognition of Prior Learning (RPL):
You may be eligible for credit towards courses in your program if you have already met the learning/competency outcomes through previous learning and/or industry experience. To be eligible for credit towards a course, you must demonstrate that you have already completed learning and/or gained industry experience that is:
• Relevant
• Current 
• Satisfies the learning/competency outcomes of the course
Please refer to http://www.rmit.edu.au/students/enrolment/credit to find more information about credit transfer and RPL.
 


Study and learning Support: 
Study and Learning Centre (SLC) provides free learning and academic development advice to you. 
Services offered by SLC to support your numeracy and literacy skills are:
assignment writing, thesis writing and study skills advice 
maths and science developmental support and advice
English language development
Please Refer http://www.rmit.edu.au/studyandlearningcentre to find more information about Study and learning Support


Assessment Submission:
Turnitin
Turnitin is an online text-matching service which can be used to support academic integrity and address plagiarism. All submissions via Turnitin within Canvas include the relevant wording for the e-Submission authorisation process. Students are to use Turnitin. to verify that the work submitted is their own work and referenced accordingly. This software will be used by all staff to ensures original work by students is checked at the submission of the assessment.
e-Submission

The University is obliged to obtain clear student authorisation on all assessable works. RMIT’s e-Submission process provides a valid authorization equivalent to a signature on a paper cover sheet allowing students to submit assessment works electronically.
The e-Submission process requires that specific wording and a link to the assessment declaration is included in your assessment documentation in order to comply with legal and statutory obligations, and can be used with all RMIT teaching technologies, including;
• Canvas
• WebLearn
• RMIT’s Google Apps for Education (Gmail, Drive, Sites etc.)
The use of fully electronic submissions saves significant time for both staff and students.

Good practice
• Providing clear advice to students on the e-Submission process as part of their assessment expectations assists in ensuring that it is straightforward for RMIT students to submit work electronically.
• Students can submit non-electronic works via conversion by a digital scanner, i.e. paper-based assessments can be scanned and submitted for assessment via the e-Submission process.
• Establishing a Turnitin assignment in Canvas is a quick way to provide an e-Submission process for a class group.
Students must submit all assessment task electronically via Canvas as directed by their teacher. 
Students are not to email or hand assessment tasks to teachers in class, corridor or cafeteria etc


Late submission:
If you require an Extension of Submittable Work (assignments, reports or project work etc.) for 7 calendar days or less (from the original due date) and have valid reasons, you must complete and lodge an Application for Extension of Submittable Work (7 Calendar Days or less) form and lodge it with the Senior Educator/ Program Manager.

The application must be lodged no later than one working day before the official due date. You will be notified within no more than 2 working days of the date of lodgement as to whether the extension has been granted.
If you seek an Extension of Submittable Work for more than 7 calendar days (from the original due date) must lodge an Application for Special Consideration form under the provisions of the Special Consideration Policy, preferably prior to, but no later than 2 working days after the official due date.
Assignments submitted late without the approval of an extension will not be accepted or marked.
Refer to RMIT University Policies and Procedures, verify for most recent version.
 

Special consideration:

Plagiarism:
Plagiarism may occur in oral or written presentations. Plagiarism is the presentation of another person’s work, idea or creation as one’s own; without appropriate referencing. Plagiarism is not acceptable. The use of another person’s work or ideas must be acknowledged. Failure to do so may result in charges of academic misconduct, which may result in cancellation of results and exclusion from your course.
