PURPOSE OF THE UNIT STANDARD 
A learner who has achieved this unit standard will be competent in:
Growing sugar crystals to achieve required crystal size and molasses exhaustion. 

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
To enter a learning programme for this unit standard or to be assessed against this unit standard, the learner is assumed to have:
  • Literacy and communications NQF 1
  • Numeracy NQF 1
  • Basic understanding of sugar processing
  • Basic knowledge of quality assurance systems
  • An understanding of general safety in the workplace at NQF 1 or equivalent 

  • UNIT STANDARD RANGE 
    General guide for scope, context and level

    The learner is expected to perform the specific outcomes as reflected in this unit standard without direct supervision, but with access to standard operating procedures. 

    Specific Outcomes and Assessment Criteria: 

    SPECIFIC OUTCOME 1 
    Demonstrate an understanding of growing sugar crystals. 
    OUTCOME NOTES

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
