Overview of Assessment



Assessment Tasks

Assessment for this course forms part of the Advanced Diploma of Oral Health (Dental Hygiene).
Training is mapped to the Australian Dental Council June 2011 “Professional attributes and competencies of the newly qualified dental hygienist” and the Dental Board of Australia “Scope of Practice”.
Students must abide by the 2012 “ADA Guidelines for Infection Control Second Edition”, 2010 NHMRC “Australian Guidelines for the Prevention and Control of Infection in Healthcare” and Worksafe Victoria “Occupational Health and Safety Regulations 2007”.
Primary assessment involves on-going practical and applied assessment in a clinical workplace or simulated environment such as a supervised student clinic.
Assessment is typically based around written and/or online tests, assignments, reflective journals, evidence portfolio’s, logbooks and/or practical demonstrations.
Competency based training requires the student to be in attendance in order for assessment to be undertaken. Please refer to definition of Vocational Competency (;ID=xjog855ryrtq;STATUS=A;SECTION=3;PAGE_AUTHOR=Penny%20Mercer).
Assessment is undertaken through successful completion of all assessment activities and classroom, project & industry participation. Assessment will also be undertaken replicating workplace conditions (as far as possible), and where relevant undertaken in the clinical setting. Assessments are spaced across the duration of the course, in order for your teacher to provide you with progressive feedback.
Feedback will be provided throughout the semester in class and/or online discussions, through individual and group feedback on practical exercises and by individual consultation.
If you have a long term medical condition and/or disability it may be possible to negotiate to vary aspects of the learning or assessment methods. You can contact the program coordinator or the Disability Liaison Unit if you would like to find out more.
The RMIT assessment policy outlines your responsibilities as a RMIT student as well as those of your teachers (
