Abstract
Nowadays, it is an important issue to diagnose and provide educational support to mathematically gifted students who are seen as the potential to develop societies. Literature review and existed practices reveal that there is no common and clear way to diagnose mathematically gifted students. In this study, it was aimed to explain the adaptation studies of Test of Mathematical Abilities for Gifted Students (TOMAGS), which was developed by Ryser and Johnsen (1998) into Turkish Language. TOMAGS was a norm referenced, standardized test and in this study, steps that Hambleton (2002) proposed for adaptation of an achievement test were followed. In this regard, first of all, language and cultural adaptations were conducted and then, psychometric analysis was carried out based on the results obtained from implementation of the test with the sample consisting of 563 students whom aged ranged between 9 and 12 in different cities of Turkey. Results show validity and reliability evidences from the implementation and it was concluded that the test can also be used in Turkish Language for identifying mathematical abilities of gifted students.
