How to check the reliability of an oral test

3. • The accurate measurement of oral ability is not easy. It takes considerable
time and effort, including training to obtain valid and reliable results.
• Oral rating scales and techniques will depend upon the needs of individual
institutions.
• Create appropriate scales for scoring, which must be holistic or analytic.

4. • Oral tests for language are determined by some criteria of performance or
based on the sub-skills rubric.
• To make an oral test reliable, testers should try out to achieve consistent
performances from candidates and to achieve scoring reliability.

5. Then how to make candidates perform
consistently in an oral test?

6. There are some ways of achieving consistent
performances from candidates.
• Use more items in an oral test
• Provide clear and explicit instructions
• Candidates should be familiar with the format and testing techniques.
• Uniform and non-distracting conditions of administration should be
provided.

7. Score Reliabilty
• Score reliability is the other essential component to test reliability.
• Score reliability consideration of an oral test involves scoring and criterial levels.
• For example: (Hughes, 2000), in the Royal Society of Arts (RSA) test of the
Communicative Test of English as a Foreign Language, criterial levels such as
accuracy, appropriacy, range, flexibility, and size are used to evaluate test takers‟
oral ability

8. • To make an oral test have a higher score reliability, global scoring (or holistic
scoring) and discrete scoring (or analytic scoring) method may be adopted.
• In the end, administration should standardize oral procedures and raters of
an oral test should be trained regularly to make it more reliable
