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 
Qualifying learners are capable of performing microscopic identification and individualisation of hair. These competencies will be used within the forensic biological industry in order to provide results in forensic examinations. These results may possibly be used in the judicial process. Learners will be able to differentiate between human and animal hair and will be able to use the identified human hair for individualisation and identification purposes.

A person credited with this unit standard will be able to:
  • Apply microscocopy principles on hair comparisons.
  • Select and evaluate hair samples for microscopic examination.
  • Explain hair morphology.
  • Identify animal hair.
  • Individualise human hair.
  • Make forensic findings on hair comparison examinations. 
    		•
