This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
The use of trigonometric applications in the roofing industry is key. People credited with this unit standard are able to:
  • Name, discuss and apply the trigonometric equations.
  • Apply the relevant trigonometric equation to calculate the height of a truss.
  • Apply the relevant trigonometric equation to calculate the span and pitch of a truss. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Communication and Mathematical Literacy at NQF Level 3.

    Recognition of Prior Learning:
  • Persons who are able to demonstrate workplace experience comparable or equivalent to the competence requirements of the unit standard will be given credit, in line with assessment processes.

    Critical Cross-field Outcomes (CCFO): 

    UNIT STANDARD CCFO IDENTIFYING 
    Identify correct trigonometric equation and apply to problem solving.

    Range: Pitch, span and height. 

    UNIT STANDARD CCFO WORKING 
    Work effectively with others and in teams. 

    UNIT STANDARD CCFO ORGANISING 
    Organise and manage oneself and one's activities responsibly and effectively by gathering all relevant information to make the necessary calculations.

    UNIT STANDARD ASSESSOR CRITERIA 
    To register as an assessor, an applicant needs:
  • Detailed documentary proof of educational qualification, practical training undergone, and experience gained by the applicant (Portfolio of Evidence).
  • A recognised assessor qualification.

    In particular, assessors should assess that the learner demonstrates an ability to consider a range of options by:
  • Measuring the quality of the observed practical performance as well as the theory and underpinning knowledge.
  • Using methods that are varied to allow the learner to display thinking and decision making in the demonstration of practical performance.
  • Maintaining a balance between practical performance and theoretical assessment methods to ensure each is measured in accordance with the level of the qualification.
  • Taking into account that the relationship between practical and theoretical is not fixed but varies according to the type and level of qualification. 

  • REREGISTRATION HISTORY 
    As per the SAQA Board decision/s at that time, this unit standard was Reregistered in 2012; 2015. 

    UNIT STANDARD NOTES 
    The Outcomes that Learners achieve will be judged subject to these being achieved:
  • Within the standard time prescribed by the organisation.
  • Strictly according to the organisation`s work place procedures.

    Values:
  • The use of tasks and materials in the learning event plan should not discriminate against learners on any grounds prescribed in the Bill of Rights and Employment Equity Act and should promote the orientations outlined in the critical cross-field outcomes.

    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.
