Context and Conditions of Assessment

This assessment will ensure that the elements, performance criteria, performance evidence and knowledge evidence required and conditions are adhered to demonstrate competency in this unit assessment task.

Read the assessment carefully before commencing.

This is an open book assessment and will be conducted at the RTO address.

Your Assessor will use the assessment criteria in this document and will provide feedback/comments.

You must answer all the questions in the assessment tasks in your own words and own handwriting.

This assessment will be required to be completed in 8 hours

Your Trainer / Assessor will inform you of the due date for this assessment task.

Your Assessor will grade as either S – Satisfactory or NS – Not Satisfactory for the assessment. In all cases, your Assessor will provide you with feedback.

Only when all assessment tasks have been graded as S – Satisfactory you will be deemed C – Competent in the final result of the unit of competency; if you do not satisfactorily complete all the assessment tasks you will be deemed NYC – Not Yet Competent.

Re-Assessment Conditions

If the evidence is graded as NS – Not Satisfactory you will be required to re-submit the evidence. In this case, you will be provided with clear and constructive feedback based on the assessment decision so that they can improve your skills/knowledge prior to reassessment.

Where an ‘NS – Not Satisfactory’ judgment is made, you will be given guidance on steps to take to improve your performance and provided the opportunity to resubmit evidence to demonstrate competence. The assessor will determine and discuss the reasons for NS – Not satisfactory on any of the criteria and will assess you through a different method of assessment e.g. verbal/oral questioning, problem-solving exercises.

You will be notified within 10 working days of undertaking an assessment of their result in achieving competency o If a student does not complete the assessment, they should notify their trainer as to why they did not complete the assessment and if due to illness, a medical certificate must be produced. “This process is detailed more in the “Training and Assessment Policy and Procedure”

o In the above scenario, the student will be given an opportunity for reassessment within 5 working days with no reassessment fee charged.

o Students who are deemed to be Not Yet Competent (NYC) will be provided with information identifying the areas in which they failed to achieve competency. Students will then have the opportunity to repeat the assessment task within 5 working days of notification with no reassessment fee charged.

o If a student is deemed NYC in the reassessment or if the student did not approach the RTO within five working days with a valid reason for not availing themselves of the reassessment opportunity, then those students will be given a final chance to re-sit the assessment and will be charged at $200.00.

o After this, no further reassessment attempt will be provided to the student and the student will be required to repeat the whole unit with the full fee for the unit as per the fees policy of the RTO. The student will be made aware of the impact of repeating the unit may have on their student visa.

o If a student is found to be cheating or plagiarising their assessment, a $200.00 reassessment fee will be charged for reassessing the assessment within 5 working days.

o If the student is found to be plagiarising or cheating again after the conclusion of the Intervention meeting with the Course Co-ordinator, the matter will be referred to the CEO / Operation Manager which may result in the suspension or cancellation of their enrolment

o The RTO has intervention strategies, including student support services available to enable students to complete a qualification in the expected time frame. Students at risk of not completing within this time frame are identified as early as possible and an intervention strategy is put in place.

The RTO will ensure access to:

• Resources required for completion of this assessment task such as:

- classroom and study areas

- access to additional resources and references for research and completing the questions

Evidence to be submitted by the student: -

• Completed written responses to the questions in the assessment task
