  • UNIT STANDARD ASSESSOR CRITERIA 
    Assessors should keep the following general principles in mind when designing and conducting assessments against this unit standard:
  • Focus the assessment activities on gathering evidence in terms of the main outcome expressed in the title to ensure assessment is integrated rather than fragmented. Remember we want to declare the person competent in terms of the title. Where assessments at title level are unmanageable, it is necessary to then focus assessment around each specific outcome, or a group of specific outcomes.
  • Make sure evidence is gathered across the entire range, wherever it applies. Assessment activities should be as close to the real performance as possible, and where simulations or role-plays are used, there should be supporting evidence to show the candidate is able to perform in the real situation.
  • Do not focus the assessment activities on each assessment criterion. Rather make sure the assessment activities focus on outcomes and are sufficient to enable evidence to be gathered around all the assessment criteria.
  • The assessment criteria provide the specifications against which assessment judgements should be made. In most cases, knowledge can be inferred from the quality of the performances, but in other cases, knowledge and understanding will have to be tested through questioning techniques. Where this is required, there will be assessment criteria to specify the standard required.
  • The task of the assessor is to gather sufficient evidence, of the prescribed type and quality, as specified in this unit standard, that the candidate can achieve the outcomes again and again and again. This means assessors will have to judge how many repeat performances are required before they believe the performance is reproducible.
  • All assessments should be conducted in line with the following well documented principles of assessment: Appropriateness, fairness, manageability, integration into work or learning, validity, directness, authenticity, sufficiency, openness and consistency. 

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

    UNIT STANDARD NOTES 
    This unit standard replaces unit standard 13321, "Maintain fluid power/pneumatic systems", Level 4, 16 credits.
  • The term "maintain" is defined as determine faults, assess requirements for repair, remove, replace, repair, adjust, re-align, reassemble and install and test.
  • This amendment excludes hydraulic systems within its title and range. The competencies required to maintain hydraulic systems (fluid power), are dealt with in an independent unit standard. This is the main purpose for this amendment.

    Recognition of Prior Learning:

    Credits may be obtained by applying to an accredited/approved training provider/institution in order to have prior learning recognised in lieu of past work experience. Past experiences must relate to the specific outcomes contained within this unit standard. The ensuing assessment of candidates seeking recognition of prior learning should not be so onerous as to deter them from doing so.
