Additional information about the unit
  This unit supports workforce and/or vocational development for those who need to understand the principles of seafood quality science, in processing, sales or wholesale environment, or in a learning environment.
Unit purpose and aim(s) The unit is designed for use primarily by operatives and team leaders who require to understand these principles in support of workplace activities. It is also designed for those who plan to enter the fish/shellfish industry or employees who wish to expand on their existing knowledge and understanding. The aim of the unit is to assess underpinning knowledge and understanding to recognised national occupational standards.
   
Unit expiry date 30-Jun-15
   
Details of the relationship between the unit and relevant national occupational standards or other professional standards or curricula (if appropriate) This unit of assessment relates directly to Improve Sector Performance Standard (approved as National Occupational Standard) knowledge unit FP.151K Principles of seafood quality science.
Assessment requirements or guidance specified by a sector or regulatory body (if appropriate) This unit is designed to assess the underpinning knowledge and understanding of learners in the workplace context, in the principles of seafood quality science. It can be assessed on or off the job.
 
The learner must demonstrate their current knowledge and understanding, to meet all assessment criteria. Assessment methods appropriate to the needs of the learner must be used to generate satisfactory evidence of knowledge and understanding.
 
The Improve Assessment Strategy sets out the overarching assessment requirements.
