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 has been developed for the surveying occupational area and is intended for persons who aim to achieve career advancement by gaining surveying skills leading to a qualification based on unit standards. A person who has successfully completed this unit standard is able to evaluate raw data and confirm acceptance of levelling results

A person credited with this unit standard is able to:
  • Display knowledge related to levelling observations, results, and adjustments
  • Evaluate raw data and computations
  • Adjust levelling results and complete work sequence in accordance with survey standards 
    		•

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    NQF Level 5 numeracy and literacy, the ability to determine the elevation of a point by levelling will facilitate better understanding and proficiency in this unit standard.

    Recognition of prior learning.
    Any learner wishing to be assessed may arrange to do so without having to attend ad-ditional education and training. The learner and assessor will decide jointly on the most appropriate assessment procedure.

    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.
