Module 5: CHARACTERISTICS OF A GOOD TESTLesson 1: Important Thing to Remember about

Validity; Types of Validity

To be able to know and remember the importance of validity

To be able to know the types of validity and to apply correctly its purpose

To understand the difference between the types of validity by means of their

variables

Objectives:

Validityrefers to the

decisions we make, and not

to the test itself or to the measurement

Important Things to Remember About Validity

•not all or nothing concept

never totally absent or absolutely perfect.

What does

Validity

do???

ESTIMATE Which

is called

validity coefficient

* Ranges from 0-1.

Validity can never be finally determined

It is specific to each administration of the test.

Types of Validity

Content Validity

Criterion- related Validity

Concurrent Validity

Construct Validity

Predictive Validity

Content Validity

A type of validation that refers to the relationship between a test and the instructional objectives

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.

Things to remember about validity:

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

Construct

Validity

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

Predictive

Validity

•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.

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

In Summary…Characteristics of a good

testa.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. Types of Evidence

CONTENT VALIDITY-

refers to the ADEQUACY and REPRESENTATIVENESS of learning outcomes to be

measured
