The new method of identification(so called the method of observation ＆ recommendation) for the gifted in korean traditional and western music was applied to the gifted education in Korea. So the check-list for teachers of the gifted was involved in the 1st step of identification. But it emerged that many problems with relevant to validity of identification. The government requires the differentiated structure of gifted education. The valid discrimination tool is necessary for the arrangement of education policy and getting a national budget, supporting of positive psycho-social mood to the gifted. I have developed the observation scale for teachers of the gifted (OSTG) in korean traditional and western music that is one of scale for discrimination and identification. Furthermore I have verified the validity and reliability of OSTG. As a result of reliability analysis, internal consistency reliability of OSTG verified cronbach`s a=.604. In order to construct valid OSTG, a factor analysis was conducted with 50 items. As a result of factor analysis, I collected 31 items finally. The validity of OSTG will be supported after a confirmatory factor analysis will have conducted through follow-up research. I expect the input of OSTG to gifted educational fields, and rising diverse debates about the method of identification to the gifted in Korean traditional and Western music.
