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 
The purpose of the learning is:

Learners who are assessed as competent against this unit standard will be able to demonstrate competence in the understanding and application of physics and chemistry science in a construction materials testing laboratory -working under supervision.

This unit standard will enable Learners to make physical measurements, read various instruments, record scientific information, mix various chemicals and operate laboratory equipment like scales, ovens and burners - working under supervision.

This competence is fundamental - that is this competence is required to enable learners to successfully master the core and elective unit standards that form an integrated part in construction materials testing.

Its contribution to socio-economic transformation is that learners would be able to undergo RPL-assessment and thereby receive recognition for previous learning and experience. The employability and career prospects of learners can therefore be enhanced by this qualification.

Previously disadvantaged individuals with this qualification can progress to the level 4 qualification - this will enable them to start their own businesses supplying a construction materials testing service - a process that will accelerate economic transformation and give economic empowerment 

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING

    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.
