This research aims at describing empirically on how to do evaluation on item quality of test result for mathematics conducted by school in improving the test instrument quality and assessment result. This test is multiple choices, where value 1 is intended for correct answer but value 0 for incorrect answer. This research was conducted at PPs UNJ, in April until Mey 2009. A finding outcome concludes that the evaluation on the test items quality can be found out by a parameter quality of the test item for model 3P. Within an empirical example is acknowledged that the Mathematics test with total 40 test items is found that there are 7 unsuitable items with model, and 33 test items that are good enough to be used and entirely this test is effective for the test participant target with competency ranging from -1,0 |
