The document discusses the importance of validity in test construction and identifies three main types of validity: content validity, which refers to how well the test items align with the objectives being measured; criterion-related validity, which examines the correlation between test scores and external criteria; and construct validity, which refers to how well test scores are explained by theoretical constructs. Validity is specific to each test administration and is determined through evidence rather than absolute measures, with the most important type for classroom teachers being content validity.

3. Important Things to Remember
About Validity
Validity
refers to the
decisions we
make, and not to
the test itself or to
the measurement

4. •not all or

6. Validity can never be finally determined
It is specific to each
administration of the test.

7. Types of Validity
Content Validity
Criterion- related
Validity
Construct Validity Predictive Validity
Concurrent Validity

8. Content Validity
A type of validation that
refers to the relationship
between a test and the
instructional objectives

10. Things to remember about
validity:
The evidence of the content validity of your
test is found in the Table of Specification.
This is the most important type of
validity to you, as a classroom teacher.
There is no coefficient for content
validity. It is determined judgmentally,
not empirically.

11. Criterion- related Validity
Criterion- related validity is a
type of validation that
refers to the extent to
which scores from a test
relate to theoretically
similar measures.

12. • a type of validation that refers
to a measure of the extent to
which a test measures a
hypothetical and unobservable
variable or quality
• refers to a measure of 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 the later time.

13. Concurrent Validity
A type of validation that requires
the correlation of the predicator
or the concurrent measure with
the criterion measure.
The higher the validity coefficient,
the better the validity evidence of
the test

14. In Summary…
Characteristics of a good test
a. Valid -----refers to the extent to which
measure what is purpose to measure.
b. State that if the test item is congruent
to the behavior to be tested it is then
valid.
