In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

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

PURPOSE OF THE UNIT STANDARD 
This unit standard reflects the skills, knowledge and values required to apply tread rubber to prepared tyre casings.

Learners credited with this unit standard are able to:
  • Use tools and operate equipment safely and effectively to prepare and apply the tread rubber.
  • Perform a range of tasks related to preparing and applying the tread rubber.
  • Identify problems while working and take corrective action.
  • Apply knowledge of tyre types and their tread rubber requirements and of material properties when performing tasks related to preparing and applying the tread rubber.

    This unit standard may be assessed in the context of either the hot or the precure retread process. 
    		•

    		•


    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
  • Any individual wishing to be assessed (including through RPL) against this unit standard may apply to an assessment agency, assessor or provider institution accredited by the relevant ETQA, or an ETQA that has a Memorandum of Understanding with the relevant ETQA.
  • Anyone assessing a learner against this unit standard must be registered as an assessor with the relevant ETQA, or an ETQA that has a Memorandum of Understanding with the relevant ETQA.
  • Any institution offering learning that will enable achievement of this unit standard or assessing this unit standard must be accredited as a provider with the relevant ETQA, or an ETQA that has a Memorandum of Understanding with the relevant ETQA.
  • Moderation of assessment will be conducted by the relevant ETQA at its discretion.

    The integrated assessment should be based on a summative assessment guide. The guide will specify how the assessor will assess different aspects of the performance and will include:
  • Evaluating evidence in a portfolio of evidence, particularly projects which integrate various aspects of the unit standard and which demonstrate the integration of knowledge, skills and values, and the development of the critical outcomes.
  • Observing and listening to the learner at work, both in primary activities as well as in other interactions, or in relevant simulations.
  • Asking questions and initiating short discussions to test understanding and to verify other evidence.
  • Looking at records and reports.
  • Formative assessment.

    Assessment of competence for this unit standard is based on experience acquired by the learner in the workplace, within the particular tyre retreading context. The assessment process should cover the explicit tasks required for the unit standard as well as the understanding of the concepts and principles that underpin the process.

    The assessment process should also establish how the learning process has advanced the Critical Cross-field Outcomes.

    The learner may choose in which language he/she wants to be assessed. This should be established as part of a process of preparing the learner for assessment and familiarising the learner with the approach being taken.

    Assessors should also evaluate evidence that the learner has been performing consistently over a period of time.

    The assessment for this unit standard can be done in conjunction with assessment for other unit standards related to a qualification, and in conjunction with the assessment for the qualification as a whole.

    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.
