Integrated assessment
Integrated assessment at the level of this qualification will evaluate the learner’s capacity to integrate engineering principles, processes and behaviour across a range of workplace domains and thus be able to carry out maintenance, repair and installation work under supervision for the benefit of his employer.
Integrated assessment must specifically evaluate the learner’s ability to:
Understand and apply mathematics literacy, communicate and behave appropriately.
Understand and use tools, instruments and equipment safely and purposefully.
Understand and apply the engineering principles and safety considerations related to the specific workplace tasks and environment.
This will require assessment methodologies which will include demonstration, oral and written responses, both summative and formative, and evidence of these in the form of portfolios or projects. The learner must show sufficient evidence of ability to understand engineering principles and responsibility in workplace behaviour and procedures. Such ability may be obtained in a formal learnership, by practice gained in the workplace (RPL) or by a combination of formal learning and practice in the workplace. The assessment must also ensure that learners have achieved the critical outcomes.
