Evidence Required

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 competence in this unit must be relevant to workplace operations and satisfy all of the requirements of the performance criteria required skills and knowledge and the range statement of this unit Assessors should ensure that candidates can

identify the specific characteristics and needs of marine aquatic invertebrates and apply these to the best practice industry standard of housing socialising feeding and health management

classify and identify invertebrates by developmental stage sex condition colours markings and other identifying features using industry terminology

safely and humanely catch and handle invertebrates

assess water quality for suitability for maintained species

report and document treatments behaviours and other information on individual animals in accordance with animal welfare regulations industry guidelines and workplace protocols and procedures

The skills and knowledge required to provide basic care of marine aquatic invertebrates must be transferable to a range of work environments and contexts and include the ability to deal with unplanned events

Context of and specific resources for assessment

Assessment of this unit is to be practical in nature and will most appropriately be assessed against the types of processes required in the industry sector in which candidates are working or in a situation that reproduces normal work conditions Workplaces can include aquariums pet shops zoos animal technology facilities or similar workplaces

There must be access in either situation to a range of marine aquatic invertebrates as well as relevant information equipment andor resources to enable one to demonstrate competence Assessment must cover a minimum of three commonly available marine aquatic invertebrate species

Method of assessment

To ensure consistency in ones performance competency should be demonstrated to industry defined standards on more than one occasion over a period of time in order to cover a variety of circumstances and where possible over a number of assessment activities

The assessment strategy must include practical skills assessment Suggested strategies for this unit are

written andor oral assessment of candidates required knowledge

observed documented and firsthand testimonial evidence of candidates application of practical tasks

simulation exercises that reproduce normal work conditions

thirdparty evidence

workplace documentation

portfolio

This unit may be assessed in a holistic way with other units of competency relevant to the industry sector workplace and job role

Guidance information for assessment

Assessment methods should reflect workplace demands eg literacy and numeracy demands and the needs of particular target groups eg people with disabilities Aboriginal and Torres Strait Islander people women people with a language background other than English youth and people from low socioeconomic backgrounds


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.
