The study population was 21860 people participating in ALES made in the periods of both 2011 spring and 2011 autumn. The sample of the study was 2186 individuals, respectively selected %10 of population randomly via computer. In the study, the internal consistency was calculated without eliminating items by using KR-21 formula because data were raw scores. Analyzes were carried out because of the fact that internal consistencies were high without eliminating agents of heights. Linear and equipercentile methods applied separately to the raw scores of sizes. Error quantities were measured by WMSE formula to determine which equating method was more appropriate for research and when the data of research findings were analyzed it was found that WMSE coefficient of equipercentile method was lower. As a result of this study equipercentile equating was found more This paper is based on the first author's master thesis titled as Test Equating Study Concerning to ALES (Academic Personnel and Postgraduate Education Entrance Exam) Scores Obtained at Different Times in a Year under the supervision of the second author. i Copyright © The Author(s).

Introduction Every year tests such as Academic Personnel and Postgraduate Education Entrance Exam (ALES), Civil Servant Selection Test KPSS , Civil Servants’ Language Profiency Test (KPDS), Interuniversity Council Language Proficiency Test (UDS), Language Proficiency Test (YDS), Vertical Transfer Test (DGS), Student Selection Test (OSS), Postgraduate Placement Test (LYS) and High Education Entrance Test (YGS) are centrically carried out by The Assessment, Selection and Placement Centre (OSYM) in Turkey. Some tests such as YDS, ALES, KPDS and UDS are carried twice a year by the OSYM and their scores are valid for a few years. Different forms of tests are applied because of some security precautions for the entrance examination of college/university or other institutions for selecting the personnel. It is not possible that all the features of the test to be the same (such as the reliability of the test, the difficulty level/strength of the test items, the variant of the test...) eventhough the developers of the test for OSYM try to prepare equivalent tests. So that reason, it is necessary to have these equating to compare the points taken from different forms. The method to make these points transformed each other and compared is test equating. Angoff (1971) defined test equating as to transform the unity system of a form to another unity system of a form. This definition is the most clearly explained definition of the term. According to Kolen and Brennan (2004), however, test equating is a statistical process which organizes the differences between the forms that have gathered form these forms. However, Braun and Holland (1982) defined test equating as a quantitative regulation made to enable the interchangeably use of the scores collected form the forms which have different difficulty level.
