Abstract :
This paper presents evidence for the validation of an Achievement Test
of 8th class Science. A teacher-made test was used consisting of 30
multiple choice items from the 8th grade science curriculum. The test was
applied to 150 sample students selected by random sampling technique.
The test was analyzed by using three techniques for validating the test,
these were, individual item’s difficulty level technique, technique of
discrimination power of the items and distractor analysis technique. The
study concluded that twelve items of the test were good and these items
can be included in the next test, while, six items of the test were hard and
needed to be improved. In addition to this, twelve items of the test
needed revision. The study recommended that the teacher should be
provided with advance special training in test construction. Furthermore,
to make the process of item analysis easy and efficient, a computerized
testing system is required to be established.
