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:

interpret symbols and abbreviations on plans and drawings

define the placement and function of irrigation structures

plan for construction works on the site

select and verify system components

provide instructions to staff on the site.

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 include:

Ability to:

read contour maps and interpret elevations and distances

marking out procedures

interpret technical drawings and site plans

calculate pressures, flows, velocities and friction losses

determine efficiency of the system with varying system components

follow relevant enterprise OHS and environmental procedures

use literacy skills to read, interpret and follow organisational policies and procedures, develop sequenced written instructions, record accurately and legibly information collected and select and apply procedures to a range of tasks

use oral communication skills/language competence to fulfil the job role as specified by the organisation including questioning, active listening, asking for clarification, negotiating solutions and responding to a range of views

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

Required knowledge includes:

Knowledge of:

interpretation of plans and general and technical specifications

hydraulic calculations

selection of water pumping and distribution components delivery based on specifications and requirements

pumps and pumping system components

erosion control and design principles

levels and levelling

earthmoving principles

principles of native topsoil conservation and protection

Occupational Health and Safety (OHS) and environmental legislation, codes of practice and enterprise procedures.

Range Statement

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, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Irrigation designs may include:

plans, drawings and specifications covering low volume, sprinkler, moving sprinkler, surface or irrigation drainage systems.
