PURPOSE OF THE UNIT STANDARD 
This unit standard reflects the skills, values and knowledge required by people in the sub-field of Forestry and/or wood technology who must be able to demonstrate an understanding of the influence of wood structure and properties.

The qualifying learner is capable of describing the influence of wood structure and properties, and certain production factors on its quality.

People credited with this Unit Standard are able to:
  • Explain the wood quality requirements generally specified by the main users of wood products.
  • Describe the effect of wood growth properties on quality requirements.
  • Describe the effect of machined wood properties on these quality requirements.
  • Describe the effect of the drying out process of wood on these quality requirements. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    It is assumed that a Learner who wishes to enter a learning programme for this Unit Standard will be able to demonstrate:
  • Communication and Mathematical Literacy at NQF Level 3 or equivalentUnderstanding the structure of wood and its relationship to its strength and appearance, and how it holds water. 

  • UNIT STANDARD RANGE 
  • The typical scope that this Unit Standard covers the "Range" as described in the specific outcomes of this unit standard.
  • The typical context of this unit standard is the training of a Learner at NQF Level 4 in the effect of wood growth and production factors on its quality.
  • The level assigned to this unit standard, i.e. NQF Level 4, is appropriate because:

    > For foundational competence the learner has to demonstrate possession of wide- ranging technical skills, a broad knowledge base incorporating some basic theoretical concepts, and the ability to access, analyse and evaluate information independently.
    > For practical competence the learner has to show the ability to operate in a variety of familiar and unfamiliar contexts under broad guidance and evaluation, and select from a considerable choice of procedures.
    > For reflexive competence the learner has to demonstrate the ability to handle complete responsibility for quantity and quality of own output, and possibly for those of others.
