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

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

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

The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:

set out and excavate trenches using manual equipment and a machine operator

check trench depth and grade

lay bedding materials

position irrigation and/or drainage of varying types and sizes

install pipe joints and fittings to job specification.

Context of and specific resources for assessment

Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.

Required Skills and Knowledge

Required skills

identify hazards and adopt safe work practices

read and interpret scale drawings and specifications

use hand signals for communicating with machine operator

measure trench width, depth, grade and location

lay and join irrigation pipe

level cover with existing ground

use power tools and hand tools

handle materials safely

work safely to instructions

use oral communication skills/language competence to fulfil the job role as specified by the organisation including questioning, active listening, asking for clarification and seeking advice from supervisor

use interpersonal skills to relate to people from a range of social, cultural and ethnic backgrounds and with a range of physical and mental abilities.

Required knowledge

OHS requirements for excavating, filling trenches and laying pipes, including relevant legislation regulations and codes

irrigation and/or drainage pipes, types and sizes

hand and power tools and equipment

bedding and backfill materials and handling methods

scale drawings for laying irrigation and/or drainage pipes

hand signals for communication

OHS issues and procedures related to trenching and pipe laying

Quality Assurance procedures for excavating, filling trenches and laying pipes

environmental impacts and procedures for laying pipe.

Range Statement

The range statement relates to the unit of competency as a whole.
