The purpose of this study was to survey the elementary school teachers’ perceptions on Attention Deficit Hyperactivity Disorder. For this purpose, this study conducted a questionnaire survey of 188 elementary school teachers from July 30 to Aug. 11, 2011 and draw the conclusion as follows: First, it was found that most of the elementary school teachers had a higher level of knowledge of ADHD, the way how to cope with it, and teaching methods for ADHD. In special education-related training, teachers' knowledge, need, and coping showed no statistically significant differences between the group with a training and the group without one. On the other hand, statistically significant differences have been found in the teaching method. Second, many teachers were found to appeal their difficultities due to children with ADHD, and also found to want to get actual assistance in the mediation of children with ADHD. Through these results, this study could confirm that it's necessary to establish diverse contents of a well-support program for teachers, and interactive support network with an expert group.
