4. This refers to the appropriateness of
the score-based inferences; or
decisions made based on the
students’ test results.
5. The degree to which evidence and
theory support the interpretations
of test scores entailed by the
proposed uses of a test. (APA,
1991).
6. Is a universally considered the most
important feature of a testing program.
It encompasses everything relating to the
testing process that makes score
inferences useful and meaningful.
(Ebel, 1961).
11. IMPORTANT THINGS TO REMEMBER IN CONTENT
VALIDITY
1. The evidence of the content validity of your test is found in the
Table of Specifications (TOS).
2. This is the most important type of validity to us, as classroom
teacher.
3. There is no coefficient for content validity. It is determined
judgmentally, not empirically.
12. Criterion- Related Validity
A type of validation that refers to the extent to
which scores from a test relate to theoretically
similar measures; or it looks at the relationship
between a test score and an outcome.
13. - It is a measure of how accurately a student’s current test score can
be used to estimate a score on a criterion measure, like
performance in courses, classes or another measurement
instrument.
- Some other variables used as criteria are ratings of performance,
ratings of adjustment, units produced in a certain period of time,
amount of sales, and number of errors made.
14. Predictive Validity
– refers to the “power” or usefulness of test scores to predict future
performance.
- A type of validation that measures the extent to which a person’s
current test results can be used to estimate accurately what that
person’s performance or other criterion, such as test scores, will be at a
later time.
Example: Admission test for college entrance, or driving performance
for drivers’ license exam.
15. Concurrent Validity – is determined when test
scores and criterion measurement/s are either
made at the same time (concurrently) or in close
proximity to each other.
- There is no time interval is involved between
the administration of the new test and the
criterion or established test.
16. CONSTRUCT VALIDITY
- A type of validation that measures the extent to which a test
measures a hypothetical and unobservable variable or
quality.
- It is determined by investigating the psychological qualities,
traits, or factors measured a test.
Examples: Intelligence, math achievement, performance
anxiety.
17. FACTORS AFFECTING THE VALIDITY OF A TEST
ITEM
The test itself
The administration and scoring of a test
Personal factors influencing how student’s response to the
test
Validity is always specific to a particular group.
18. FACTORS THAT REDUCE THE VALIDITY
OF THE TEST ITEM
Poorly constructed test item
Unclear directions
Ambiguous items
Inadequate time limit
Improper arrangement of items
