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. |
1 | Prepare for glass laser measurement and levelling | 1.1 | Task requirements are determined by inspection of glass window and door components to be installed in a building and following relevant plans, drawings and texts in accordance with the work plan |
| | 1.2 | Appropriate laser levelling equipment for the installation job is selected and set up to manufacturer recommendations |
| | 1.3 | Levelling is planned in detail including sequencing and prioritising tasks and system requirements |
| | 1.4 | Potential hazards to personnel and other building components at the installation site are identified and prevention and/or control measures are selected in accordance with the work plan |
| | 1.5 | Individual’s roles and responsibilities within the installation team are identified, and where required, assisted with provision of on-the-job training for the tasks |
2 | Use laser devices to make measurements | 2.1 | Measurements are taken accurately, interpreted and recorded correctly to standard operating procedures |
| | 2.2 | Laser levelling devices are operated to manufacturer specifications or standard operating procedures |
| | 2.3 | Datum point is set up or located |
| | 2.4 | Readings are taken to datum and at nominated or selected stations, to project specifications |
3 | Perform levelling | 3.1 | Levelling realignment calculations are performed using correct and appropriate method for the installation levelling/alignment application |
| | 3.2 | Glass window and door components are levelled and aligned to specifications using correct and appropriate techniques, and adjustments made to ensure compliance with manufacturer specifications and the work plan |
| | 3.3 | Glass components are temporarily fixed in the assigned installation positions prior to final measurement |
| | 3.4 | Final level and alignment inspections are undertaken, any adjustments made and glass components fixed to the building using appropriate fasteners |
4 | Complete work | 4.1 | Glass installation rating compliance certificate is completed |
| | 4.2 | Levelling equipment is closed own and appropriate personnel notified of completed installation in accordance with enterprise requirements |
| | 4.3 | Work area is cleared of waste, cleaned, restored and secured in accordance with site/enterprise procedures |
| | 4.4 | Plant, tools and equipment are maintained and stored in accordance with site/enterprise procedures |
| | 4.5 | Work completion details are finalised in accordance with enterprise procedures |
Accurately select, set and use laser levelling devices to obtain and interpret specified measurements
Maintain and store laser levelling devices
Read, interpret and follow information on standard operating procedures, manufacturer recommendations, drawings and other applicable reference documents
Set up levelling equipment and take levelling measurements and perform necessary calculations
Confirm accuracy of the readings taken, including set up and movement of laser levelling device in two locations
Level and align a range of glass window and door components for installation in buildings
Confirm work requirements and specifications and the report work outcomes and problems and follow safety procedures
Avoid backtracking, work flow interruptions or wastage
Work with others and in a team by recognising dependencies and using cooperative approaches to optimise work flow and productivity

Assessors must:
hold training and assessment competencies as determined by the National Skills Standards Council (NSSC) or its successors
have vocational competency in the furnishing industry at least to the level being assessed with broad industry knowledge and experience, usually combined with a relevant industry qualification
be familiar with the current skills and knowledge used and have relevant, current experience in the furnishing industry.
Assessment methods must confirm consistency of performance over time rather than a single assessment event and in a range of workplace relevant contexts.
Assessment must be by observation of relevant tasks with questioning on underpinning knowledge and, where applicable, multimedia evidence, supervisor’s reports, projects and work samples.
Assessment is to be conducted on single units of competency or in conjunction with other related units of competency. Foundation skills are integral to competent performance in the unit and should not be assessed separately.
Assessment must occur on the job or in a workplace simulated facility with relevant process, equipment, materials, work instructions and deadlines.
Access is required to laser levelling equipment, glass window and door components, work instructions, manufacturer documentation and organisational guidelines.
