Overview of assessment requirements

A person who demonstrates competency in this unit will be able to perform the outcomes described in the Elements to the required performance level detailed in the Performance Criteria. The knowledge and skill requirements described in the Range Statement must also be demonstrated. For example, knowledge of the legislative framework and safe work practices that underpin the performance of the unit are also required to be demonstrated.

Critical aspects of evidence to be considered

Suitable procedures are developed.

New procedures are documented.

Appropriate models are used and/or created.

Context of assessment

On the job or in a simulated work environment.

Method of assessment

The following assessment methods are suggested:

observation of the learner performing a range of workplace tasks over sufficient time to demonstrate handling of a range of contingencies

written and/or oral questioning to assess knowledge and understanding

completion of workplace documentation

third-party reports from experienced practitioners

completion of self-paced learning materials including personal reflection and feedback from trainer, coach or supervisor

Evidence required for demonstration of consistent performance

Evidence will need to be gathered over time across a range of variables.

Resource implications

Access to geographic information systems databases and operating systems.

The Range Statement relates to the Unit of Competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording in the Performance Criteria is detailed below.
