Abstract

Test is one common instrument, which used by most of college students who focus on experimental study and also most teachers. Items test is arranged refer to learning goal then its is tried out in an examination simulation for parralel leaners. Based on learners’ answer, can be determined the level of item tes quality. There are four description that must be contained by each item test, are proper difficulty index, empirical validity, discriminancy power, and instruments reability. It was found that tester got difficulty to choose one best quality item which contain these description, because there is no sufficient information about criteria for a best quality item test. Eventhough, applying bad quality item cause a bias for learning result measured. Generally, this research aimed to provide an correlation facts among some of these four item criteria, especially between discriminancy power and validity. The population is test instrument for students at senior high school. Twelves samples of test intrument have been chosen using purposive sampling. Data analysed by using correlation technique of SPSS analysis, also descriptively. The result of this study is dicriminancy power correlates toward item validity, with determination coofecient start from 54.8% to 82.6%. Thus, each item description is able to reflect another. Item which has higher discriminancy power value also has higher validity item value.
