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. | Perform measurements relating to swimming pool and spa servicing. | 1.1. | Measurement requirements are confirmed. |
| 1.2. | Preparations for measurement tasks are implemented. |
| 1.3. | Measurements are obtained and confirmed using established work practices, measuring equipment, and personal protective equipment (PPE) to ensure safety and security of self, others and property. |
| 1.4. | Measurements are recorded using correct measurement units. |
| | 1.5. | Measurement units are converted as required. |
| | 1.6. | Measuring equipment and materials are cleaned, checked for serviceability, calibrated, maintained and stored. |
| | 1.7. | Environmental impact of measurement activities is minimised and waste is disposed of in line with enterprise procedures. |
2. | Perform calculations relating to swimming pool and spa servicing. | 2.1. | Calculation requirements are confirmed and correct method is selected for achieving required result. |
2.2. | Calculations are performed using online and electronic calculators as required, and results are confirmed and recorded. |
2.3. | Results of calculations are interpreted to solve problems relating to swimming pool and spa servicing. |
3. | Interpret mathematical information. | 3.1. | Information represented in symbols, diagrams and pictorial representations is recognised and interpreted to complete workplace tasks. |
3.2. | Limitations of swimming pool and spa measurements and calculations, and associated risks, are identified. |
