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:

establish the requirements of the drainage system

implement operational procedures for the projec;

establish and organise resources

supervise on-site construction

commission the drainage system

rehabilitate 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.

Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assignment, checklist) and due date here

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:

interpret irrigation designs

develop operational procedures

implement employment procedures

conduct OHS risk assessment

supervise workers in:

earth moving and construction procedures

power and pumping plant installation

pump and gated pipe installation

construction of canals, channels, head ditches, beds, check structures, tailwater holding ponds

estimate quantities and volumes of soil to be moved

document requirements for structures

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:

measuring and monitoring procedures for factors contributing to drainage system performance

positive and negative environmental impacts of drainage systems

water table and salinity measures

water quality monitoring methods and techniques

soil moisture measurement procedures

water authority standards and procedures

drainage appliances/fixtures/fittings and related

level and align site

types and operational parameters of drains

components used in 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

enterprise policies and procedures

environmental role of drainage systems

environmental impacts of drainage 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, 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.

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.
