Evidence Guide 1. Critical aspects of evidence 1.1 Achieving competence Achievement of this Unit of Competence is based on each of the following conditions being met:

1.1.1 completing on more than one occasion each element of competence autonomously and to requirements in each case.

1.1.2 the Performance Criteria associated with each Element of Competence being demonstrated on a representative range of items identified in the Range of Variables; the specification as to which items are to be included for assessment purposes is provided in Part 6 of this Evidence Guide.

1.1.3 demonstrating a full understanding of all the knowledge and the performance of all the associated skills outlined in Part 3 of this Evidence Guide, under the headings

Knowledge and Skills - Basic

Knowledge and Skills - Underpinning.

1.2 Reporting requirements The reporting of judgments about competence must be in the context of the individual unit being assessed and the qualification to be issued. Where regulatory requirements apply Qualifications shall be supplemented with transcripts of information that is meaningful for maximum recognition of knowledge and skills transfer. In all other instances consideration may be given to providing similar supplementary information. Generally this would be the individual Unit of Competence titles as well as detailed statements about the achievement of knowledge and skills.

2. Interdependency of Units Interdependency generally needs to be considered as part of State/Territory arrangements under Occupational Health & Safety, Lift Regulations or Codes of Practice or other regulatory requirements. Issues related to work operations near live electrical parts or near moving parts or rotating machinery is of particular importance.

4. Resource Implications Resources for this unit require access to plant and equipment that is normally available in the workplace. Where knowledge and skills development is considered to be best acquired away from the work site then appropriate learning resources and facilities are required.

5. Consistency of Performance Competency should be judged from evidence collected across the whole range of activities, with regards to the requirement outlined in the elements of competence, the Range of Variables (ROV) and from evidence of knowledge underpinning performance, to ensure all aspects of performance are achieved.

6. Context of Assessment It is not necessary for assessment of competence to be demonstrated on every item of equipment, tools, materials or testing devices identified in the Range of Variables. What is important is to determine that individuals have the generic and transferable skill that provides them with the ability to work safely and productively.

In this context evidence related to the items in the ROV can be based on the guidelines shown in the table below. This evidence combined with other critical aspects of assessment (see Part 1 of the Evidence Guide) will provide the means by which assessment for competence can be determined.


© 19 UTL98

ROV Guideline for Conduct Structural Welding Group A is to be carried out in conjunction with Group B and Group C. This is to be demonstrated on two separate occasions.

The term ‘separate occasion’ means the items identified on which the skill is demonstrated are separated by time and location. The demonstration of a skill on the second and subsequent occasions should be on a different item(s), where appropriate.

Group No

The minimum number of items on which skill is to be demonstrated

List of items from the Range of Variables

A At least 3 Applications horizontal flat overhead vertical

B At least 1 Materials mild steel stainless steel rolled steel (low carbon)

C At least 1 Plant single phase arc welder three phase arc welder single phase gas shielded three phase gas shielded

Using this guideline to support any assessment strategy or process does not remove the responsibility of employers and employees to ensure appropriate ‘duty of care’ arrangements are maintained under relevant Occupational Health & Safety Legislation.

In the assessment process it should be acknowledged that State/Territory regulatory requirements and/or Codes of Practice may vary. Therefore there may be a requirement for the demonstration of a greater range of items to those specified and/or listed in the table above.

Competencies apply to work over a wide range of equipment including different types of control systems and equipment spanning a wide age range. Competencies at this level will be demonstrated on non-routine equipment where discretion is required to plan and select the appropriate equipment and techniques.

Systems include traction lifts (including group systems); electrohydraulic lifts; escalators; moving walks
