Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Evidence Guide

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessment must confirm the ability to assist in the preparation, construction and maintenance of a number of lengths of road/track using a combination of locally won and prefabricated materials such as PSP. The road/track construction must include the installation of drainage and crossings.

Assessment must also confirm the ability to:

assist in the construction of a road/track in accordance with job instructions and technical specifications

use tools, plant and equipment

construct drainage and crossings

carry out road maintenance tasks

interactively communicate and work in a team

Consistency in performance

Competency should be demonstrated over a time frame that allows for the preparation, construction and maintenance of roads and tracks under a range of field conditions.

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the workplace or in a simulated workplace environment.
