Although all forms of assessment are concerned with the use of evidence, each form of assessment may have a specific purpose. It is the purpose, which will define the nature, the process and the format of assessment documents and activities.
The purpose of assessment instruments and tools
The purpose of assessment instruments and tools are to collect and record valid, authentic, sufficient and consistent evidence.
Assessment instruments and tools ensure standardisation and the maintenance of the quality of assessment.
An assessor should never do any assessment without prepared assessment instruments or tools.
It is therefore imperative that assessment activities are constantly reviewed and evaluated against national unit standards and the criteria provided by the quality assurance bodies.
