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 evidence required to demonstrate competence in this unit
Assessment must confirm the ability to:
assess weather conditions before undertaking a dive
assist in lifting and handling activities
enter and leave the water according to standard dive procedures
search and survey under water for targeted items
undertake harvesting and maintenance diver duties required on an aquaculture site
use basic tools and auxiliary equipment under water
use dive signals when communicating

Assessment must confirm knowledge of:
diver communication systems
local climatic conditions
maintenance procedures on an aquaculture site
seafood species common to the enterprise or industry
search and survey techniques
Context of and specific resources for assessment
Assessment is to be conducted at the workplace or in a simulated work environment.

Resources may include:
suitable diving environment
diving equipment
aquaculture apparatus and associated equipment
tools used in the aquaculture sector
any relevant auxiliary devices
Method of assessment
The following assessment methods are suggested:
observation of practical demonstration
practical exercises
written or oral short-answer testing
Guidance information for assessment
This unit may be assessed holistically with other diving units.
