B. Research Objects
The objects of this study are five sets of English test items of National Examination year 2012 for senior high schools, which were intended to be
administered in Yogyakarta. The researcher got the copy of the test from an English teacher in SMA Negeri 7 Yogyakarta who had taught in SMA Bopkri 2
Yogyakarta . The samples of English test items of the National Examination year
2012 are for natural science and social science. Since both majors have the same lesson objectives which are incorporated in Competence Standard and Basic
Competence, the test is same for both majors. There are five versions for the test, namely A57, B69, C71, D43, and
E45. Furthermore, the English test of National Examination is divided into two sections, they are listening and reading section. The listening section which was
composed in only a version consists of fifteen questions starting from number one up to number 15 while the reading section of each test version consists of 35
questions starting from number 16 up to 50 for all five versions. Therefore, the total items on an English test of National Examination year 2012 for senior high
schools items are 50 items of each test version.
