Correct Answer - Option 2 : Reliability
A test is a kind of assessment to measure the knowledge, skills, and aptitude in a specified field. There are generally oral and written types of tests. The written tests can be short answer type, objective type, long answer type, and essay type tests.
-
Standardized tests are concerned with the whole field of knowledge or ability tested. These are useful in comparing the achievement of individual groups. These expert-made tests can be used on a national level as they are based on the uniform curriculum.
The criterion of a good standardized test:
| Objectivity |
- It means that the personal assumptions and pre-thoughts of the examiner should not affect the scores of the child.
- It affects both reliability and validity.
|
| Reliability |
- It implies accuracy and consistency in behavior.
- A reliable test should give essentially the same score when administered twice to the same sample of the population or by the same or different examiners.
|
| Validity |
- A test is said to be valid if it actually measures what it is supposed to be measured.
-
Reliability is a necessary condition for validity, but validity is not necessary for reliability.
|
| Comprehensiveness |
- A test is said to be comprehensive when it includes all the topics/subjects of the test content.
- It should give equal importance to each topic.
|
| Usability |
- A good test should be easy, attractive, and interesting and must be convenient to both the teacher and the students.
- It means that no difficulties should come across while using a specific test.
|
| Diagnostic |
- It should diagnose the weaknesses and strengths of the children.
- Also, it must diagnose the qualities for which it is made.
|
| Clearness |
- The directions given to the students should be brief and definite so that children may avoid wrong performance due to misunderstanding of direction.
|
Hence, it could be concluded that reliability criteria refers to consistency of test scorers.
