    Critical Cross-field Outcomes (CCFO): 

    UNIT STANDARD CCFO IDENTIFYING 
    Identify and solve problems and make decisions using critical and creative thinking.

    Note:
  • The ability of the candidate to identify and assess evidence of seismic damage with reasons for the damage and compile a report. 

  • UNIT STANDARD CCFO WORKING 
    Work effectively with others as members of a team, group, organisation or community.

    Note:
  • The ability and willingness of the candidate to accept and interpret work instructions correctly and to request assistance with identification and assessment in an appropriate manner as a team member. 

  • UNIT STANDARD CCFO ORGANISING 
    Organise and manage themselves and their activities responsibly and effectively.

    Note:
  • In preparation for identification and assessment of seismic damage, the candidate must indicate what tools are required and communicate to fellow workers his/her intentions. 

  • UNIT STANDARD CCFO COLLECTING 
    Collect, analyse, organise and critically evaluate information.

    Note:
  • The ability of the candidate to reconcile the measured and analysed data with visual information and prepare a written report. 

  • UNIT STANDARD CCFO COMMUNICATING 
    Communicate effectively, using visual, mathematical and/or language skills in the modes of oral and/or written presentations.

    Note:
  • The appropriate communication with the relevant personnel with regard to reporting evidence of seismic damage will indicate his/her proficiency in effective communication. 

  • UNIT STANDARD CCFO SCIENCE 
    Use science and technology effectively and critically showing responsibility towards the environment and health of others.

    Note:
  • The use of seismic monitoring devices and instrumentation indicate effective use of science and technology.

    Unit Standard Justification:

    Level:

    Attribute; Level; Justification:
  • Skills; Level 3; The skills required now have a significant variety and extend beyond the simple range.
  • Procedures; Level 2; Although the procedure is known and familiar (as level 1) it is not as repetitive.
  • Context; Level 3; The candidate knows all contexts that the process occurs in but a variety and range of contexts occur.
  • Knowledge; Level 2; The knowledge required is merely related to the operation and no theory needs to be applied.
  • Information processing; Level 2; Information is readily available but some processing is required.
  • Problem Solving; Level 3; The key difference from level two is the application of some "judgement".
  • Orientation of activities; Level 3; Follows instructions, but has some autonomy to make own decisions and give instructions down ward.
  • Orientation of scope of responsibility; Level 3; Here the responsibility extends towards, although not entirely, the output as well as, when applicable, the output of others.
  • Application of responsibility; Level 3; Candidate's output is quality checked, i.e. on random basis.

    Average Level = 24/9 = 2.67.
    Actual Level Assigned = 3.

    Credits:

    Total hours required by the learner to achieve the required outcome:

    Activity; Hours:
  • Classroom Teaching; 16 Hours.
  • On-The-Job Training; 24 Hours.
  • Mentoring required; 0.
  • Other (Specify); 0.

    Total = 40.

    Credits Achieved = 40/10 = 4.

    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.
