1.  Assessor Guidelines

 

1.1  Introduction to Assessment

Assessment Overview

Assessment consists of a task or series of tasks set in order to obtain information about a learner’s competence.  These tasks can be assessed in a variety of ways using different assessment techniques throughout the learning process.

During the assessment process information about the learner’s achievements is identified, gathered and interpreted.  Different types of evidence are gathered by using a variety of assessment methods.  After collecting the evidence, an assessor will assess and record the evidence against the outcomes.

 

U  Tip:

As such, assessment can be defined as a structured process in which evidence of performance is gathered and assessed against agreed criteria.

 

 

 

Assessment Principles

 

 

After the purpose of assessment is clearly stated, it is necessary to ensure that the principles of assessment are applied.  They are:

 

No. Principles Description
1 Appropriateness

 

Make sure that the method of assessment is suited for the performance being assessed
2 Fairness

 

The method chosen to assess the achievements must be fair and must not present any barriers that are not related to the evidence
3 Manageable

 

The methods that you use must be easy accessible, cost-effective and must not interfere with the learning.

 

4 Time efficient

 

Be sure that the assessment does not interfere with the normal daily activities or productivity of the learner.

 

5 Integration into work or learning

 

The collection of evidence must be integrated into the work or learning process at the appropriate time and it must be feasible.

 

6 Validity

 

The assessment must be valid in the sense that it must fit the purpose.

 

7 Direct

 

The assessment must imitate the work conditions of the learner as closely as possible.  Assessment can be direct (structured interviews) or indirect (video).

 

8 Authenticity The evidence that the learner submit must be to the satisfaction of the assessor and must normally bare the signature of the learner or parties involved.
9 Sufficient The evidence must cover all the criteria that have been established and the performance must be on the required standard.  Thus, there must be sufficient to have enough evidence.
10 Systematic

 

The assessment must be planned and recorded to ensure that the assessment is fair.
11 Open The learner must contribute to the planning and collecting of evidence.  The learner must understand the assessment process and the criteria used.
12 Consistent The same assessor must make the same judgement under the same or similar circumstances.
13 Current

 

The evidence that is gathered must be current and applicable

 

U  Tip:

Competence includes the ability to transfer and apply skills and knowledge, and what a person knows and can do.
