Overview of Assessment

Assessment are conducted in both theoretical and practical aspects of the course according to the performance criteria set out in the National Training Package. 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 the Assessment Task Section.

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

NYC (<50%) Not Yet Competent

CAG (50-59%) Competent - Pass

CC (60-69%) Competent - Credit

CDI (70-79%) Competent - Distinction

CHD (80-100%) Competent - High Distinction

Assessment Tasks

Assessment of this unit will involve completion of:

Assignment 1, 15%
Test 1, 20%
Team journal, 10%
Exam, 55%

In order to achieve competency in this course, students will need to demonstrate competency in each element (i.e. students will need to demonstrate at least basic understanding of fundamental concepts and the ability to solve the relevant problems). The test and exam are closed book. Formula sheet is provided by the instructor. Only scientific calculators are allowed. No aide memoire (i.e. cheat sheet) is permitted.
A record of student class activities, team reflection, class handouts, etc, is to be kept in the Team Journal. To ensure that the competency standards are being met, throughout the semester, student progress will be closely monitored.
