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. Prepare for pressing | 1.1 Review work order and construction plans and where required check with appropriate personnel. 1.2 Identify and obtain type and quantity of assembly material and hardware. 1.3 Select appropriate personal protective and other equipment and check for operational effectiveness. |
2. Set up components | 2.1 Use equipment in line with organisational safety procedures, manufacturer’s instructions and environmental protection practices. 2.2 Select timber components from pre-cut material in line with cutting list. 2.3 Position and clamp components in press, with allowable faults, joins and grain in line with construction standards and grading rules. 2.4 Set components to include camber adjustments, overhang and other design requirements. 2.5 Identify defective components, dispose of or recycle in line with environmental protection practices. 2.6 Fasten components to maintain temporary alignment during setup. 2.7 Position and install hardware on joints ready for pressing. |
3. Press trusses | 3.1 Complete pre start-up equipment checks to ensure operational effectiveness. 3.2 Set and adjust press cycle times and pressures to meet production requirements. 3.3 Check pressed trusses for abnormalities and assembly faults in line with organisational procedures. 3.4 Complete unload and reload cycles. 3.5 Assess pressed and finished trusses regularly; action changes to assembly and pressing processes as required. 3.6 Dispose of defective pressed trusses in line with environmental protection practices. |
4. Prepare products for despatch and report | 4.1 Check finished product for quality and label in line with work order. 4.2 Remove components from jigs and safely stack in designated location. 4.3 Strap, pack and label finished products ready for transportation. 4.4 Avoid wastage of strapping and packaging materials and maximise use of recycled materials. 4.5 Record and report production outcomes and equipment faults to appropriate personnel. |
A person demonstrating competency in this unit must satisfy all of the elements, performance criteria and foundation skills of this unit. If a specific volume or frequency is not stated below, then evidence must be provided that the following requirements have been performed on at least one occasion:

Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessor requirements
Assessors must:
hold the appropriate assessor competency standards as outlined in regulations; and
be able to demonstrate vocational competencies at least to the level being assessed; and
be able to demonstrate how they are continuing to develop their VET knowledge and skills as well as maintaining their industry currency and assessor competence.
