Evidence Guide
|
The Evidence Guide identifies the critical aspects, knowledge and skills to be demonstrated to confirm competence for this unit. This is an integral part of the assessment of competence and should be read in conjunction with the Range Statements |
|
Critical aspects of evidence to be considered |
Assessment must confirm sufficient knowledge of diving theory, diving equipment and industry practices and safety criteria Assessment of performance should be over a minimum of two (2) different dives covering the prescribed number of categories of the Range Statements that are applicable in the learners environment In particular, assessment must confirm the ability to apply knowledge of diving theory and practice to safely dive and perform dive rescues plan and evaluate a safe diving activity calculate repetitive diving activities using no-decompression tables participate as part of a buddy pair/team in an open water dive at depths not less than 5 metres and not to exceed 18 metres for a period not less than 20 minutes complete a safety stop at 5 metres for 3 - 5 minutes not ascend at greater than 18 metres/mi |
|
Interdependent assessment of units |
This unit must be assessed after attainment of competency in the following unit(s) SROOPS002B Plan for minimal environmental impact SROODR002A Plan outdoor recreation activities This unit must be assessed in conjunction with the following unit(s) Nil For the purpose of integrated assessment, this unit may be assessed in conjunction with the following unit(s) Nil |

Resource implications |
Physical resources - assessment of this competency requires access to suitable scuba dive locations with open water scuba equipment mask fins snorkel gas cylinders regulator buoyancy control device (BCD) weights exposure suit Human resources - assessment of this unit of competency will require human resources consistent with those outlined in the Assessment Guidelines. That is, assessors (or persons within the assessment team) must be competent in this unit but preferably be competent in the unit at the level above, i.e., SROSCB002A be competent, as a minimum, in the units SRXFAD001A, SRXRIK001A and SRXEMR001A to ensure adequate risk management during the assessment be current in their knowledge and understanding of the industry through provision of evidence of professional activity in the relevant area have attained the mandatory competency requirements for assessors under the Australian Quality Training Framework (AQTF) as specified in Standard 7.3 of the Standards for Registered Training Organisations |
|
Consistency in performance |
Due to issues such as covering all the safety and rescue implications, this unit must be assessed over a minimum of two (2) different occasions in order to ensure consistency of performance over the complete Range Statements and contexts applicable to scuba diving |
|
Context for assessment |
Competency must be demonstrated in an actual/real scuba dive activity and all relevant aspects of equipment use, dives and rescues should be assessed in an underwater environment (that is, dry land demonstration of competence is insufficient) Assessment of this unit of competence will usually include observation of processes and procedures, oral and/or written questioning on required knowledge and skills and consideration of required attitudes Where performance is not directly observed and/or is required to be demonstrated over a 'period of time' and/or in a 'number of locations', any evidence should be authenticated by colleagues, supervisors, clients or other appropriate persons |

These levels do not relate to the Australian Qualifications Framework. They relate to the seven areas of generic competency that underpin effective workplace practices. The three levels of performance (1, 2 and 3) denote the level of competency required to perform the task: Use routine approaches Select from routine approaches Establish new approaches Collecting , analysing and organising information - Collecting information on duration and depth of dive(s) and organising it in a log book Communicating ideas and information - Communicating with dive buddy during dive Planning and organising activities - Planning number of dives, depths and duration Working with teams and others - Diving with a buddy Using mathematical ideas and techniques - Calculating no-decompression limits Solving problems - Dealing with out-of-air situations Using technology - Using dive computers to record details of dive Please refer to the Assessment Guidelines for advice on how to use the Key Competencies. |
