PRINCIPLES OF LANGUAGE ASSESSMENT
Concurrent vaidity
Predicitive validity
Content-related evidence (content validity)
Direct and indirect testing
it can claim content-related evidence of validity, often popularly referred to as content validity.
Direct testing involves the test-taker in actually performing the target task.
Indirect testing, learners are not performing the task itself but rather a task that is related in some way.
Practicality
Validity
The extent to which inferences made from assessment results are appropriate, in terms of the purpose of the assessment.
Criterion-related evidence
A second form of evidence of the validity of a test
Construct-related evidence
A third kind of evidence that can support validity
is not excessively expensive
it is easy to administer
it has a scoring/evaluation procedure
Reliability
Student related reliability
Rater reliability
Test administration reliability
Test reliability
Washback
refers to the effects the tests have on instruction in terms of how students prepare for the test.
AUTHENTICITY
Bachman and Palmer (1996) define authenticity as “the degree of correspondence of the characteristics of a given language test task to the features of a target language task.”
Validity
if the test accurately predicts what it is supposed to predict
when the predictor and criterion data are collected at the same time.
