PRINCIPLES OF LANGUAGE ASSESSMENT
Content-related evidence (content validity)
Direct and indirect testing
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.
it can claim content-related evidence of validity, often popularly referred to as content validity.
Practicality
is not excessively expensive
it is easy to administer
it has a scoring/evaluation procedure
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
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.”
Concurrent vaidity
when the predictor and criterion data are collected at the same time.
Predicitive validity
if the test accurately predicts what it is supposed to predict
