1. Item Analysis

2. Item Analysis
-is a process which examines
student responses to individual
test items (questions) in order to
assess the quality of those items
and of the test as a whole.

3. - It is especially valuable in
improving items which will be
used again in later tests, but it
can also be used to eliminate
ambiguous or misleading
items in a single test
administration.

valuable for increasing
instructors’ skills in test
construction, and identifying
specific areas of course content
which need greater emphasis or
clarity.
