Overview of Assessment
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:

Assessment Tasks
1. Laboratory exercises (20%)
Each student will complete 8 practical exercises designed to reinforce the theory topics taught during the semester.
Most practical exercises consist of two major parts:
Part A is a prior task includes only calculations (usually pre requisite for part B) and part B include measurements and graphs.
The results obtained in part B will be reviewed and compared with the calculations from section A.
These will be assessed progressively according to individual task criteria and each student is required to complete all the parts/tasks for each laboratory exercise.
All laboratory exercises must be undertaken according to safe working practice and performed according to specified laboratory standards and practice including calibration, measurement and accurate reading. This must include electrical measurement taken with safe working practice, meters properly calibrated, meter settings positioned for an accurate reading and accurate readings taken for all measurements.
2. Project based assignment (10%)
An assignment has to be undertaken toward the end of the unit, in a controlled environment for the specified duration in order to perform tasks autonomously.
The assignment circuits can be constructed using either hard ware or MultiSim (design / test) simulation computer package. Each student will complete all parts of the assignment individually and will be asked by the supervisor to demonstrate that the circuit is functioning according to specifications. Each student is required to complete a written report includes three major parts: calculations, circuit diagrams / measurement and results / conclusion.
3. Written Test (20%)
Theoretical concept covered in weeks 1 to 8 will be assessed by a written test in week 9 (for ET1A and ET1B only).
For MET 1 group,theoretical concept covered in weeks 1 to 8 will be assessed as part of the written final exam.
4. Written Exam (50%)
Theoretical concept covered in weeks 9 to 16 will be assessed by a written Exam in week 17 / 18 (exams period).
