In order to gain credits for this Unit Standard you will need to prove to an assessor that you are competent. The Class Activities throughout your Learner Workbook are designed not only to help you learn new skills, but also to prove that you have mastered competence. You will be required to develop a Portfolio of Evidence to hand in to an assessor so that you can be assessed against the outcomes of this Unit Standard. Where you encounter a Class Activity icon, you must complete the formative assessment activity in the Learner Workbook. Comprehensive guidelines for the development of your Portfolio of Evidence may be found in the Learner Portfolio of Evidence Guide for the particular learning programme that you are working with.
