List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions. |
1. Interpret plans or designs and create layouts | 1.1 Identify and verify design inputs. 1.2 Check computer software for currency and use to prepare roof truss layouts and production documentation. 1.3 Resolve design requirements outside software limitations. |
2. Review and test design options | 2.1 Review and test roof truss layouts for optimal suitability for stakeholders. 2.2 Use effective processes to optimise roof truss layout and ensure stakeholder objectives are met. |
3. Provide advice on design, production and installation issues | 3.1 Prepare and document production and installation advice. 3.2 Communicate documented advice to all stakeholders, prior to and following installation. |
4. Manage roof truss outputs | 4.1 Certify roof truss design layouts in line with regulatory and organisational requirements and communicate to relevant stakeholders. 4.2 Store and maintain drawings and documentation in line with organisational procedures. |
