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 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 fish and apply these to the best practice industry standard of housing, socialising, feeding and health management
classify and identify marine fish by age, sex, reproductive status, condition, colours, markings and other identifying features using industry terminology
assess water quality for suitability for maintained species
safely and humanely catch, handle and restrain fish
report and document treatments, behaviours and other information on individual fish where relevant in accordance with animal welfare regulations, industry standards, workplace protocols and procedures.

The skills and knowledge required to provide basic care of marine fish 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 includeaquariums, pet stores, zoos, animal technology facilities, catchers or distributors or similar workplaces.

There must be access to a range of animals as well as relevant information, equipment and/or resources to enable one to demonstrate competence. Assessment must cover a minimum of three commonly available marine fish species.

Method of assessment
To ensure consistency in one's 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 responsibilities over a number of assessment activities.

The assessment strategy must include practical skills assessment. Suggested strategies for this unit are:
written and/or oral assessment of candidate's required knowledge
observed, documented and first-hand testimonial evidence of candidate's application of practical tasks
simulation exercises that reproduce normal work conditions
third-party 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 (e.g. literacy and numeracy demands) and the needs of particular target groups (e.g. 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).
