Assessment

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit's learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines. Students will be expected to demonstrate the following required skills: - following work instructions, standard operating procedures (SOPs) and safe work practices; - obtaining and interpreting data from job instructions and relevant sources to establish required outcomes; - determining the appropriate calculation method to suit the application; - performing calculations and confirming answer/s, and; - producing and interpreting simple charts and graphs from given data.Students will also be expected to demonstrate the following knowledge: - safe work practices and procedures; - formulae applicable to the determination of perimeter, area and volume of simple geometric shapes and the reasons for using dimensions with the same units; - techniques and procedures for rounding off figures when estimating approximate answers; - features and use of mixed numbers, decimals, fractions and whole numbers; - procedures for carrying out calculations involving fractions and using each of the four basic rules of addition, subtraction, multiplication and division; - concept of percentage and procedures to be followed in converting a decimal and fraction to a percentage; - concepts and calculations of ratio and proportion; - scales applicable to the axes of the graphs or charts; - types of charts and/or graphs used in the individual's field of work; - upper and lower limits of acceptability applicable to data entered on a graph or chart; - trends indicated by the slope or gradient of a graph; - action to be taken when given trends occur or set limits are approached on graphs or charts; - procedures for drawing 'lines of best fit', and; - trends indicated by the graphs or charts drawn.
