2. Practicality
An effective test is practical
It is not excessively expensive.
It stays within appropriate time
constraints.
It is relatively easy to administer.
It has a scoring or evaluation
procedure that is specific and
time efficient.
3. Reliability
A reliability test is consist and dependable.
If the test is given to the same student or
matched student on two different
occasions, the test should yield the similar
result.
Factors contribute to the unreliability of a
test:
- Student-Related Reliability
- Rather Reliability
- Test administration Reliability
- Test Reliability
Unreliability may also result the conditions
in which the test is administered.
4. Validity
Validity is the extent to which
inferences made from assessment
results are appropriate, meaningful,
and useful in terms of the purpose of
the assessment.
A valid test of reading ability actually
measures reading ability, nor
previous knowledge in a subject, nor
some other variable of questionable
relevance.
5. These five types of evidence
that can support validity:
Content-Related Evidence
Criterion-Related Evidence
Construct-Related Evidence
Consequential Validity
Face Validity
