Assessment Tasks

The assessment is conducted in both theoretical and practical aspects of the course according to the Performance Criteria and Required Skill and Knowledge of the unit of the Accredited Course. 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:
CHD Competent with High Distnction
CDI Competent with Distinction
CC Competent with Credit
CP Competent with Pass
NYC Not Yet Competent

Assessment Criteria (for Practical)
CHD Competent with High Distinction Students should be able to complete the project given basically without help. The learner will demonstrate an exceptionally clear understanding of the subject matter and appreciation of the issues. Arguments will be well formed and sustained, and problem solving will be well thought out and structured

CDI Competent with Distinction Students should be able to complete the project with minimal help. The learner will demonstrate a detailed understanding of the key issues, but perhaps lacking in the finer points. The learner will demonstrate a clearly developed, relevant and well-structured approach while working on the practical exercises.

CC Competent with Credit The learner will demonstrate a competent understanding of the subject but with minor gaps, and will demonstrate a well prepared and presented approach to problem solving.

CP Competent with Pass The learner demonstrates some appreciation of the subject matter, but the work is generally lacking in depth and with gaps. Work at this level may be poorly presented and contain some minor errors.

NYC Not Yet Competent The learner will show evidence of minimal or inadequate understanding of the subject matter.

Assessment Task
You are required to complete the following three assessment tasks:

1. Test 1 (20%)- Week 8
2. Final Practical Test (30%) - Week 15
3. Final Closed book Test (50%) - Week 16
