After item analysis, the result showed that the
Economics achievement test has a high face and content validity. The test item validity was determined through
Difficulty and discrimination indices. A difficult index or p-value of 0.5 for each item was considered after applying
the formula of correction for guessing. The discrimination index was established through point biserial statistics for
each item with a correction coefficient of at least 0.3. The test has a reliability coefficient of 0.95 established through
the use of Kuder-Richardson formula 20.The test is valid and reliable for assessing students internally and prepare
them for external examinations.
