Overview of Assessment

A person who demonstrates competency in this unit must be able to apply metallurgy principles to NDT test selection and interpretation. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

The assessment is conducted in both theoretical and practical aspects of the course according to the performance criteria set in the National Training Package. Assessment may incorporate a variety of methods including written/oral activities and demonstration of practical skills to the relevant industry standards.
Participants are advised that they are likely to be asked to personally demonstrate their assessment activities to their teacher/assessor.
Feedback will be provided throughout the course. To successfully complete this course you will be required to demonstrate competency in each assessment task detailed under Assessment Tasks section of Course Guide Part B.
 


Assessment Tasks

You are required to complete the following two assessment tasks:
 
1. Practical Lab - Week 9 - 30% weighting
2. Closed book Test - Week 13 - 70% weighting

 

The assessment is conducted in both theoretical and practical aspects of the course according to the performance criteria set
in the National Training Package. The students are required to undertake summative assessments that bring together knowledge
and skills.

To successfully complete this course you will be required to demonstrate competency in each assessment tasks detailed
under Assessment Task Section.

Your assessment for this course will be marked using the following table:

CHD Competent with High Distinction

CDI Competent with Distinction

CC Competent with Credit

CAG Competency Achieved – Graded

NYC Not Yet Competent

DNS Did Not Submit for assessment

All assessment tasks need to be successfully completed to demonstrate competence.

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.
