Overview of Assessment
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.
Feeback will be provided throughout the course
Evidence can be gathered through a variety of ways including:
observation of processes and procedures;
oral and/or written questioning on required knowledge and skills;
testimony from supervisors, colleagues, clients and/or other appropriate
persons;
inspection of the final product or outcome;
a portfolio of documentary evidence.
Graded Assessment out of 100 Marks will be based on the results obtained for Assignments/Practical reports/Unit tests/Exams.
Students must gain pass in all forms of assessment in order to pass the competency.
Assessment Tasks
Your knowledge and understanding of the course content is assessed through completion of four assessment tasks. All the assessment tasks allow you to apply the required knowledge and skills in relation to applications of fluid mechanics.
The assessment for this subject will consist of:
1. Assignment 1 (Minor) - 20%
2. Assignment 2 (Major) - 30%
