Required Skills

This describes the essential skills and knowledge and their level, required for this unit.

Required skills:

prepare, collect, label and preserve blue green algae samples

produce reports and logs

plan work activities

work effectively as part of a team

identify and obtain resources

follow plans and instructions

apply procedures and standards

communicate work requirements

use literacy skills in regard to verbal and written communication in the workplace

use personal protective equipment.

Required knowledge:

types and purposes of blue green algae samples

procedures and techniques for blue green algae sampling

sample preparation, including:

prevention of contamination

volume of sample

appropriate containers

preservation

location selection

location maintenance

equipment

transportation

documentation procedures for samples

legislative and organisational policies, procedures and standards

communication systems

work planning processes

hazards associated with collection of blue green algae samples.

Evidence Required

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

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

The candidate should demonstrate the ability to perform blue green algae sampling, including:

planning and preparing for sampling tasks

collecting samples according to sampling plan

maintaining integrity of samples

recording required information.

Context of and specific resources for assessment

Access to the workplace and resources including:

documentation that should normally be available in a water industry organisation

relevant codes, standards and government regulations.

Where applicable, physical resources should include equipment modified for people with disabilities.

Access must be provided to appropriate learning and assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the language and literacy capacity of the candidate and the work being performed.

Validity and sufficiency of evidence requires that:

competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace

where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice

a decision of competence should only be made when the assessor has complete confidence in the person's competence over time and in various contexts

all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence

where assessment is for the purpose of recognition (RCC/RPL), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time

assessment can be through simulated project-based activity and must include evidence relating to each of the elements in this unit.

In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the skill levels of the operator and cultural issues that may affect responses to the questions, and will reflect the requirements of the competency and the work being performed.


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.
