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 GISc occupational area and is intended for persons who aim to achieve career advancement by gaining GISc skills leading to a qualification based on unit standards. A person who has successfully completed this unit standard is able to perform spatial error analysis.

A person credited with this unit standard is able to:
  • Display a knowledge and understanding of spatial sampling.
  • Display a knowledge and understanding of correlation analysis.
  • Display a knowledge and understanding of linear spatial analysis techniques.
  • Display a knowledge and understanding of non-linear spatial analysis techniques. 
    		•

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
  • NQF mathematics (measurement, descriptive statistics, probability, probability distributions).
  • NQF level 4 Language, literacy and communication.

    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
    Moderation
  • Anyone assessing a learner against this unit standard must be registered as an assessor with the relevant ETQA.
  • Any institution offering learning that will enable achievement of this unit standard or will assess this unit standard must be accredited as a provider with the relevant ETQA and registered with FE / HE registrar.
  • Moderation of assessment will be overseen by the relevant ETQA according to the moderation guidelines in the relevant qualification and the agreed ETQA procedures.

    Therefore anyone wishing to be assessed against this unit standard may apply to be assessed by any assessment agency, assessor or provider institution that is accred-ited by the relevant ETQA.

    UNIT STANDARD ASSESSOR CRITERIA 
    Assessors should keep the following principles in mind when designing and conduct-ing 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 assessment at title level is un-manageable, then focus assessment around each specific outcome, or groups of specific outcomes.
  • Make sure evidence is gathered across the entire range, wherever it applies. Assessment activities should be as close to the real perform-ance 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 as-sessment 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 question-ing techniques. Where this is required, there will be assessment crite-ria to specify the standard required.
  • The task of the assessor is to gather sufficient evidence, of the pre-scribed type and quality, as specified in this unit standard, that the can-didate 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, man-ageability, integration into work or learning, validity, direct, authentic, sufficient, systematic, open and consistent.

    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.
