    Critical Cross-field Outcomes (CCFO): 

    UNIT STANDARD CCFO IDENTIFYING 
    Identify and solve problems and make decisions using critical and creative thinking. The ability of the learner to identify sub-standard and hazardous conditions, assess and take appropriate action e.g. identifying and respond to deviations from normal operating conditions. 

    UNIT STANDARD CCFO COLLECTING 
    Collect, analyse, organise and critically evaluate information. The ability of the candidate to reconcile the information from visual and physical examinations and constantly evaluate the changing situation e.g. operating refrigeration equipment. 

    UNIT STANDARD CCFO SCIENCE 
    Use science and technology effectively and critically showing responsibility towards the environment and health of others e.g. operating refrigeration equipment. 

    UNIT STANDARD CCFO DEMONSTRATING 
    Demonstrate an understanding of the world as a set of related systems by recognising that problem-solving contexts do not exist in isolation. The ability of the candidate to identify and refer anomalous behaviour to a specialist confirms understanding that a specific observation, inference, action or decision can have a devastating effect e.g. identifying and respond to deviations from normal operating conditions.

    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.
