Practicality
Not excessively expensive
Easy to administer
Evaluation is time-efficient and specific
Appropriate time constrains
Validity
Content-related evidence (content validity)
Direct testing
Student actually performing on the target task.
Indirect testing
Students don't perform the task itself but rather a task that is related in some way.
Criterion-related evidence
Concurrent validity

Accuracy in measuring intended criteria
Impact on the preparation of test-takers
Effect on the learner
Social consequences

How students react to first seeing the test
A well constructed, expected format with familiar tasks
Clear directions
Reasonable difficulty
Related tasks to their coursework
