Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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:

plan and prepare for the work

inspect the site to determine access to drainage lines

isolate appliances/fixtures/fittings and related assemblies

use manual and mechanical drain clearing equipment

troubleshoot drainage problems and implement repair/replacement strategies

maintain drainage infrastructure and vegetative cover.

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.


Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills include:

Ability to:

isolate appliances/fixtures/fittings and related assemblies

repair or remove blockages

use manual and mechanical drain clearing equipment

level and align site

implement and follow relevant enterprise OHS and environmental policies and procedures

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

use oral communication skills/language competence to fulfil the job role as specified by the organisation, including questioning techniques, active listening, clarifying information and consulting with supervisors as required

use numeracy skills to estimate, calculate and record routine workplace measures

use interpersonal skills to work with 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:

types and operational parameters of irrigation drains

components used in irrigation drainage systems

isolation processes and procedures

levelling and alignment processes

regulatory requirements, codes of practice and relevant enterprise service standards relating to blockage removal, disconnection and reconnection activities

environmental impacts of drainage systems

application of OHS procedures when locating and clearing line blockages, use of personal protective equipment and materials handling.

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 drainage systems may include:

both surface and sub-surface drainage installed to handle water which is excess to plant requirements in an irrigated area.

Drainage earthworks and embankments may include:

surface drains

culverts

mole drains

sand slit

sub-surface traps

pit and trap systems

dune and swale systems

reed beds

water-recycling pumps and baffles.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
