Required Steps in the Building of an Educational Test's Validity Argument
What are the Essentials of the Validation Process?
Known as the three types of reliability evidence: test-retest evidence, alternate-form evidence, and internal consistency evidence
What is the Trio of Reliability Indicators?
The consistency with which an educational test measures what it is measuring
What is Assessment Reliability?
Evidence collected of a score-based inference's accuracy
What is STEP ONE in the validation process?
Coefficients represent the stability with which a test is measuring what it is measuring
What is test-retest evidence?
Centers on the strength of an argument regarding a test's interpretive accuracy and also its fitness for purpose
What is Assessment Validity?
Evidence collected of this inference's suitability for a test's purpose
What is STEP TWO in the validation process?
Evidence deals with the degree to which different forms of a test yield results that are consistent.
What is alternate-form reliability evidence?
Calls for educational test to be accompanied by evidence about the accuracy of score-based inferences and evidence of the contribution of those inferences to the achievement of a test's purpose
What is Assessment Validity?
Generation of a reasoned validity argument based on steps 1 and 2
What is STEP THREE in the validation process?
The conception of consistency focused on the consistency among the test's items in what they are measuring.
What is internal consistency evidence?
A reflection of the consistency with which a test is measuring whatever it's measuring
What is Assessment Reliability?
When Popham describes the nature of assessment validity, these two terms are often employed.
What is an INFERENCE and an INTERPRETATION?
Focuses on the decision that's based on a student's score
What is decision-consistency estimates?
The most important concept in all of educational testing
